How to upgrade Angular CLI to the latest version

Question

Using ng --version I got       angular cli  1 0 0   which is not the latest release available   Since I have Angular CLI globally installed on my system  in order to upgrade it I tried   npm update angular-cli -g  But it does not work  because it stays to 1 0 0 version

In addition to  ShinDarth answer   I did what he said but my package did not updated the angular version  and I know that this post is about angular-cli  but i think that this can help too    so after doing what  ShinDarth said above  to fix my angular version I had to create a new project with -ng new projectname that generated a package  copy the new package  then paste the new package on all projects packages needing update  remember to add the dependencies you had and change the name on first line  or you can just change the versions manualy without copy and paste  then run -npm install    Now my ng serve is working again  maybe there is a better way to do all that  if someone know  please share  because this is a pain to do with all projects that need update

To update Angular CLI to a new version  you must update both the global package and your project s local package   Global package   npm uninstall -g  angular cli npm cache clean   if npm version is  gt  5 then use  npm cache verify  to avoid errors  or to avoid using --force  npm install -g  angular cli latest   Local project package   rm -rf node modules dist   use rmdir  S Q node modules dist in Windows Command Prompt  use rm -r -fo node modules dist in Windows PowerShell npm install --save-dev  angular cli latest npm install   Source  Github

The following approach worked for me  npm uninstall -g  angular cli  then npm cache verify  then npm install -g  angular cli  I work on Windows 10  sometimes I had to use  npm cache clean --force as well  You don t need to do if you don t have any problem during the installation

In my case  I have installed angular-cli locally using npm install --save-dev angular-cli  So  when I use command npm install -g  angular cli  it generates error saying that  Your global Angular CLI version  1 7 3  is greater than your local version  1 4 9    Please note that angular-cli   angular cli and  angular cli latest are two different cli s  What solves this is uninstall all cli and then install latest angular cli using npm install -g  angular cli latest

After reading some issues reported on the GitHub repository  I found the solution  In order to update the angular-cli package installed globally in your system  you need to run  npm uninstall -g  angular-cli npm install -g  angular cli latest  Depending on your system  you may need to prefix the above commands with sudo  Also  most likely you want to also update your local project version  because inside your project directory it will be selected with higher priority than the global one  rm -rf node modules npm uninstall --save-dev  angular-cli npm install --save-dev  angular cli latest npm install  thanks grizzm0 for pointing this out on GitHub  After updating your CLI  you probably want to update your Angular version too  Note  if you are updating to Angular CLI 6  from an older version  you might need to read this  Edit  In addition  if you were still on a 1 x version of the cli  you need to convert your angular-cli json to angular json  which you can do with the following command  ng update  angular cli --from 1 7 4 --migrate-only   check this for more details

If you have any difficulties managing your global CLI version it is better to use NVM  MAC  Windows   To update the local CLI in your Angular project follow this steps   Starting from CLI v6 you can just run ng update in order to get your dependencies updated automatically to a new version    ng update  angular cli   With ng update sometimes you might want to add --force flag     You can also pass --all flag to upgrade all packages at the same time   ng update --all --force   If you want just to migrate CLI just run this   ng update  angular cli --migrateOnly   You can also pass flag --from from- version from which to migrate from  e g --from 1 7 4  This flag is only available with a single package being updated  and only on migration only      After update is done make sure that the version of typescript you got   installed supported by your current angular version    otherwise you might need to downgrade the typescript version  Also bear in mind that usually the latest version of angular won t support the latest version of the typescript        Checkout Angular CLI   Angular   NodeJS   Typescript compatibility versions here   Also checkout this guide Updating your Angular projects and update angular io    OLD ANSWER  All you need to do is to diff with angular-cli-diff and apply the changes in your current project    Here is the steps    Say you go from 1 4  to 1 5 then you do https   github com cexbrayat angular-cli-diff compare 1 4 0   1 5 0 click on File changed tab Apply the changes to your current project  npm install   yarn Test all npm scripts  more details here  https   stackoverflow com a 45431592 415078
