npm global path prefix

Question

I am being more cautious than usual because I have been confused by the behavior of npm in the past    I am on a Mac and have installed node js through brew install node    Now that I want to run jslint js on the command-line as the command jslint I find that the canonical way to accomplish this is sudo npm install -g jslint which ran successfully with this output      sudo npm install -g jslint npm http GET https   registry npmjs org jslint npm http 200 https   registry npmjs org jslint npm http GET https   registry npmjs org jslint - jslint-0 1 9 tgz npm http 200 https   registry npmjs org jslint - jslint-0 1 9 tgz npm http GET https   registry npmjs org nopt npm http 200 https   registry npmjs org nopt npm http GET https   registry npmjs org nopt - nopt-1 0 10 tgz npm http 200 https   registry npmjs org nopt - nopt-1 0 10 tgz npm http GET https   registry npmjs org abbrev npm http 200 https   registry npmjs org abbrev npm http GET https   registry npmjs org abbrev - abbrev-l 0 4 tgz npm http 200 https   registry npmjs org abbrev - abbrev-1 0 4 tgz  usr local share npm bin jslint - gt   usr local share npm lib node modules jslint  bin jslint js jslint 0 1 9  usr local share npm lib node modules jslint  -- nopt 1 0 10  abbrev 1 0 4    Subsequently    jslint ply js zsh  command not found  jslint   due to  usr local share npm bin not being in my  PATH    1  Why did brew not install global npm bin path to path  Maybe it did  but something zsh does is messing it up  Where might I be able to find that  2  Should I do this   Append   usr local share npm bin to the exported  PATH at the bottom of my    zshrc   It seems like this isn t the right way to do it because if I install something else later  using Homebrew or something  I ll be needing to append it to my zsh startup script to set the path  I guess in this particular instance it s just a matter of the npm install -g not making the right symlinks in a  proper  location  like  usr local bin maybe    I think what I will do is manually build out symlinks inside  usr local bin for any programs that I have trouble with and it should be good enough for my purposes    EDIT  I m updating this in 2019  because this old question is popular but now outdated both in terms of my personal workflow and also in terms of how to best go about installing node and managing its various dependencies    My personal workflow is now to use the installer obtained from nodejs org to install node on systems  I actually trust this more than the homebrew package itself  because it knows best how to manage the files  If you want to change your system node from 8 10 to 10 15  whether on Mac or Windows  simply download the installer from nodejs org for 10 15 for your OS  Attempting to upgrade node installed via homebrew has always proven to be a more difficult approach in my experience   Also  the biggest thing to point out is that the use of sudo as shown in my npm install of jslint example above is highly discouraged  I am fairly certain that homebrew packages should never be installed or interacted with in any way using the superuser  It should not be necessary  and will lead to file permission headaches   Furthermore I recommend ESLint over jslint  and have not used jslint in years

brew should not require you to use sudo even when running npm with -g. This might actually create more problems down the road.

Typically, brew or port let you update you path so it doesn't risk messing up your .zshrc, .bashrc, .cshrc, or whatever flavor of shell you use.

Extending your PATH with    export PATH  usr local share npm bin  PATH     isn t a terrible idea  Having said that  you shouldn t have to do it   Run this   npm config get prefix   The default on OS X is  usr local  which means that npm will symlink binaries into  usr local bin  which should already be on your PATH  especially if you re using Homebrew    So    npm config set prefix  usr local if it s something else  and Don t use sudo with npm  According to the jslint docs  you should just be able to npm install it    If you installed npm as sudo  sudo brew install   try reinstalling it with plain ol  brew install  Homebrew is supposed to help keep you sudo-free

Spent a while on this issue  and the PATH switch wasn t helping  My problem was the Homebrew node npm bug found here - https   github com npm npm issues 3794  If you ve already installed node using Homebrew  try     Note per comments that this might not be safe  It worked for me but could have unintended consequences  It also appears that latest version of Homebrew properly installs npm  So likely I would try brew update  brew doctor  brew upgrade node etc before trying       npm update -gf   Or  if you want to install node with Homebrew and have npm work  use   brew install node --without-npm curl -L https   npmjs org install sh   sh

I use brew and the prefix was already set to be     npm config get prefix  Users  user   node   I did notice that the bin and lib folder were owned by root  which prevented the usual non sudo install  so I re-owned them to the user    cd  Users  user   node   chown -R  user   group  lib   chown -R  user   group  bin   Then I just added the path to my  bash profile which is located at  Users  user   PATH  PATH    node bin

I managed to fix Vue Cli no command error by doing the following    In terminal sudo nano    bash profile to edit your bash profile  Add export PATH  PATH  Users  your username   npm-packages bin Save file and restart terminal Now you should be able to use vue create my-project and vue --version etc     I did this after I installed the latest Vue Cli from https   cli vuejs org   I generally use yarn  but I installed this globally with npm npm install -g  vue cli  You can use yarn too if you d like yarn global add  vue cli  Note  you may have to uninstall it first globally if you already have it installed  npm uninstall -g vue-cli  Hope this helps

If you have linked the node packages using sudo command  Then go to the folder where node modules are installed globally   On Unix systems they are normally placed in  usr local lib node or  usr local lib node modules when installed globally  If you set the NODE PATH environment variable to this path  the modules can be found by node   Windows XP -  USERPROFILE  Application Data npm node modules Windows 7 -  AppData  npm node modules  and then run the command  ls -l   This will give the list of all global node modules and you can easily see the linked node modules

sudo brew is no longer an option so if you install with brew at this point you re going to get 2 really obnoxious things  A  it likes to install into  usr local opts or according to this   usr local shared  This isn t a big deal at first but i ve had issues with node PATH especially when I installed lint  B  you re kind of stuck with sudo commands until you either uninstall and install it this way or you can get the stack from Bitnami   I recommend this method over the stack option because it s ready to go if you have multiple projects  If you go with the premade MEAN stack you ll have to set up virtual hosts in httpd conf  more of a pain in this stack than XAMPP plust the usual update your extra vhosts conf and  etc hosts for every additional project  unless you want to repoint and restart your server when you get done updatading things
