Question

I know Angular2 beta has just been released but I can t reproduce the steps from their official site tutorial   https   angular io guide quickstart    Maybe someone has had similar issues and knows what to do in order to fix the this  When I try to start the application with npm start command I get output like this   0 info it worked if it ends with ok 1 verbose cli    node     usr local bin npm    start    2 info using npm 2 7 4 3 info using node v0 12 2 4 verbose run-script    prestart    start    poststart    5 info prestart angular2-quickstart 1 0 0 6 info start angular2-quickstart 1 0 0 7 verbose unsafe-perm in lifecycle true 8 info angular2-quickstart 1 0 0 Failed to exec start script 9 verbose stack Error  angular2-quickstart 1 0 0 start   concurrent  npm run tsc w   npm run lite    9 verbose stack Exit status 127 9 verbose stack     at EventEmitter  lt anonymous gt    usr local lib node modules npm lib utils lifecycle js 213 16  9 verbose stack     at EventEmitter emit  events js 110 17  9 verbose stack     at ChildProcess  lt anonymous gt    usr local lib node modules npm lib utils spawn js 14 12  9 verbose stack     at ChildProcess emit  events js 110 17  9 verbose stack     at maybeClose  child process js 1015 16  9 verbose stack     at Process ChildProcess  handle onexit  child process js 1087 5  10 verbose pkgid angular2-quickstart 1 0 0 11 verbose cwd  Users tmrovsky Documents angular2 angular2-quickstart 12 error Darwin 13 4 0 13 error argv  node    usr local bin npm   start  14 error node v0 12 2 15 error npm  v2 7 4 16 error code ELIFECYCLE 17 error angular2-quickstart 1 0 0 start   concurrent  npm run tsc w   npm run lite    17 error Exit status 127 18 error Failed at the angular2-quickstart 1 0 0 start script  concurrent  npm run tsc w   npm run lite     18 error This is most likely a problem with the angular2-quickstart package  18 error not with npm itself  18 error Tell the author that this fails on your system  18 error     concurrent  npm run tsc w   npm run lite  18 error You can get their info via  18 error     npm owner ls angular2-quickstart 18 error There is likely additional logging output above  19 verbose exit   1  true     I had   typescript 1 7 5 version node 0 12 2 version  Maybe someone could help solve the problem       package json        name    angular2-quickstart      version    1 0 0      scripts          tsc    tsc        tsc w    tsc -w        lite    lite-server        start    concurrent   npm run tsc w     npm run lite             license    ISC      dependencies          angular2    2 0 0-beta 0        systemjs    0 19 6        es6-promise     3 0 2        es6-shim     0 33 3        reflect-metadata    0 1 2        rxjs    5 0 0-beta 0        zone js    0 5 10          devDependencies          concurrently     1 0 0        lite-server     1 3 1        typescript     1 7 3          index html    lt html gt    lt head gt       lt title gt Angular 2 QuickStart lt  title gt        lt  -- 1  Load libraries -- gt       lt script src  node modules es6-shim es6-shim js  gt  lt  script gt       lt script src  node modules angular2 bundles angular2-polyfills js  gt  lt  script gt       lt script src  node modules systemjs dist system src js  gt  lt  script gt       lt script src  node modules rxjs bundles Rx js  gt  lt  script gt       lt script src  node modules angular2 bundles angular2 dev js  gt  lt  script gt        lt  -- 2  Configure SystemJS -- gt       lt script gt          System config               packages                    app                        format   register                       defaultExtension   js                                                      System import  app boot                    then null  console error bind console         lt  script gt    lt  head gt    lt  -- 3  Display the application -- gt   lt body gt   lt my-app gt Loading    lt  my-app gt   lt  body gt    lt  html gt    app components ts   import  Component  from  angular2 core     Component       selector   my-app       template    lt h1 gt My First Angular 2 App lt  h1 gt        export class AppComponent      boot js   import  bootstrap  from  angular2 platform browser  import   AppComponent  from    app component   bootstrap AppComponent

This answer is for Windows 10 users only and as you ll see below  I suspect the problem is happening only for those users   To find out what is happening  you can run the command on PowerShell and it will tell you what is the actual problem   PS C  Users Laurent-Philippe gt  tsc  amp  amp  concurrently  tsc -w   lite-server  At line 1 char 5   tsc  amp  amp  concurrently  tsc -w   lite-server           The token   amp  amp   is not a valid statement separator in this version        CategoryInfo            ParserError          ParentContainsErrorRecordException       FullyQualifiedErrorId   InvalidEndOfLine   Basically  the message explains that the token   amp  amp   is not yet valid with Windows 10  And for those wondering  the same command replacing  amp  amp  with  amp   informed us that the ampersand operator is reserved for future use      amp   character is not allowed  The  amp  operator is reserved for future use  wrap an ampersand in double quotation marks    amp    to pass it as part of a string    Conclusions    if you want to manually launch this command from the powershell  you can use this instead      tsc   amp   concurrently  tsc -w   lite-server   if you want to launch your application with npm start  replace the start line in your package json by       start    tsc  amp  concurrently   tsc -w     lite-server      alternatively  the answer of user60108 also works because he is not using the ampersand       start    concurrently   npm run tsc w     npm run lite

In the package json file  I removed the line which had  prestart    npm run build   This appears to be a blocking command  and occurs before  npm  start  thus preventing the other start commands

I had the same error on OS X  node v6 2 0 and npm v3 9 3 installed with homebrew  and it was not solved by any of the above  I had to add full paths to the commands being run by concurrently   In package json  I changed this    start    tsc  amp  amp  concurrently   npm run tsc w     npm run lite        to this    start    tsc  amp  amp  concurrently    Users kyen  node bin npm run tsc w      Users kyen  node bin npm run lite        You will  of course  need to update the correct paths based on where your node global binaries are stored  Note that I didn t need to add the path to the first tsc command  It seems only concurrently needs the full paths specified

I had a similar problem after copying the angular2-quickstart folder  including node modules  to create the angular2-tour-of-heroes folder   This was wierd because the original was compiling fine but the copy was not     npm run tsc   I was able to resolve the issue by deleting the node modules folder and re-running npm install   This was a surprise to me  so I did a diff between the 2 folders     diff -rw angular2-quickstart node modules  angular2-tour-of-heroes node modules    there were a LOT of differences  a lot of  where  diffs in the package json files like this -  diff -rw angular2-quickstart node modules yargs package json angular2-tour-of-heroes node modules yargs package json 5c5  lt          Users michael Tutorials angular2 angular2-quickstart node modules lite-server  ---  gt          Users michael Tutorials angular2 angular2-tour-of-heroes node modules lite-server       which kind of makes sense but there were also some like this -  diff -rw angular2-quickstart node modules utf-8-validate build gyp-mac-tool angular2-tour-of-heroes node modules utf-8-validate build gyp-mac-tool 607c607 608  lt        return  k  self  ExpandVariables data k   substitutions  for k in data  ---  gt        return dict  k  self  ExpandVariables data k    gt                                              substitutions   for k in data       which I don t understand at all   Oh well  Hope this helps

Seemingly there is more than one way in which angular2-quickstart can fail to start  I had the same issue running Angular2 version 2 0 0 under a fresh install of node 6 6 0   npm 3 10 3 on Windows 7  In my case running npm start dumped a ton of typescript errors   c  git angular2-quickstart gt npm start   gt  angular2-quickstart 1 0 0 start c  git angular2-quickstart  gt  tsc  amp  amp  concurrently  npm run tsc w   npm run lite   node modules  angular common src directives ng class d ts 46 34   error TS2304  Cannot find name  Set   node modules  angular common src pipes async pipe d ts 39 38   error TS2304  Cannot find name  Promise           This issue is discussed in angular quickstart issue  63   typings  not being installed correctly  That ticket gives the fix as      node modules  bin typings install   which worked for me   I m not sure of the  right  way to do this yet

First you need update npm  lite-server and typescript   sudo npm update -g  amp  amp  sudo npm install -g concurrently lite-server typescript   Delete node modules folder from your Angular project directory  if exist   Next  run   npm install   After that resolve ENOSPC errors   echo fs inotify max user watches 524288   sudo tee -a  etc sysctl conf  amp  amp  sudo sysctl -p   Finally   npm start   This is my package json file     x000D   x000D    x000D     name    reservationsystem   x000D     version    0 0 1   x000D     scripts     x000D       tsc    tsc   x000D       tsc w    tsc -w   x000D       lite    lite-server   x000D       start    concurrent   npm run tsc w     npm run lite     x000D       x000D     dependencies     x000D       a2-in-memory-web-api     0 1 0   x000D       angular2    2 0 0-beta 3   x000D       es6-promise     3 0 2   x000D       es6-shim     0 33 3   x000D       reflect-metadata    0 1 2   x000D       rxjs    5 0 0-beta 0   x000D       systemjs    0 19 17   x000D       zone js    0 5 11  x000D       x000D     devDependencies     x000D       concurrently     1 0 0   x000D       lite-server     2 0 1   x000D       typescript     1 7 5  x000D      x000D    x000D   x000D   x000D

Installing the packages globally is one way to do it  but this restricts you to using the same version across all projects in which they are used     Instead  you can prefix your npm scripts with   node modules  bin  In your case  the package json would look like this        name    reservationsystem      version    0 0 1      scripts          tsc      node modules  bin tsc        tsc w    npm run tsc -w        lite      node modules  bin lite-server        start      node modules  bin concurrent   npm run tsc w     npm run lite             dependencies          a2-in-memory-web-api     0 1 0        angular2    2 0 0-beta 3        es6-promise     3 0 2        es6-shim     0 33 3        reflect-metadata    0 1 2        rxjs    5 0 0-beta 0        systemjs    0 19 17        zone js    0 5 11          devDependencies          concurrently     1 0 0        lite-server     2 0 1        typescript     1 7 5          I think npm is supposed to supply the   node modules  bin in front of each  script  command that s in that directory by default  which is why the original package json looked the way it did   I am not sure if that feature is in every release of npm  or if there s some config setting you re supposed to specify   It d be worth looking into

I encountered this same issue  However  none of the above answers were proper solutions for me  It turns out it was due more to my dev environment then any of the versions of things   Since I used Visual Studio Code  I set up a build task in VSC to compile TypeScript as a watcher  This was the issue  VSC had already started a NPM task for TSC and so when executing the tutorial s  start  script  it was having issues with the fact that VSC was still running tsc -w   I stopped the task in VSC and reran the  start  script and it worked just fine   Solution A  Stop and npm Start   VSC Command Tasks  Terminate running tasks Terminal   npm start   After that to bring everything working together I change the start script to just start the server and not actually launch TSC   Solution B  Change npm start script   Replace   start    concurrent   npm run tsc w     npm run lite     with   start    npm run lite    Solution C  Just run the lite server command   npm run lite

This answer is in relation to the excellent Pluralsight course  Angular 2 Fundamentals  by Jim Cooper   If like me you are having trouble getting started running the command npm start on a Windows 10 machine then I suggest the following   Start git bash as administrator  follow the steps in the video  Navigate to the project directory  ng2-fundamentals  and then type the following commands   npm config get registry  npm cache clean  npm install   Once the installation is complete you will need to modify the get-shell js file located in the spawn-default-shell module inside the node modules folder as follows   Change the following   const DETECT SH REGEX    sh      to this   const DETECT SH REGEX    sh     Note the   removed from the end of the sh string  credit to the original author of this fix alfian777 who posted the solution on github   Save the file and then go to your git bash console and type npm start  You shouldn t see any errors now and the localhost page will start up in your default browser  alternatively open your browser and navigate to http   localhost 8808
