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

/usr/local/share/npm/bin/jslint -> /usr/local/share/npm/lib/node_modules/jslint/
bin/jslint.js
[email protected] /usr/local/share/npm/lib/node_modules/jslint
+-- [email protected] ([email protected])
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EDIT: I'm updating this in 2019, because this old question is popular but now outdated both in terms of my personal workflow and also in terms of how to best go about installing node and managing its various dependencies.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.
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.
Simple solution is ...
Just put below command :
sudo npm config get prefix
if it's not something like these /usr/local
, than you need to fix it using below command.
sudo npm config set prefix /usr/local
...
Now it's 100% working fine
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.
Any one got the same issue it's related to a conflict between brew and npm Please check this solution https://gist.github.com/DanHerbert/9520689
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=$PATH:~/.node/bin
I managed to fix Vue Cli no command error by doing the following:
sudo nano ~/.bash_profile
to edit your bash profile.export PATH=$PATH:/Users/[your username]/.npm-packages/bin
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!
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.
Try running:
PATH=$PATH:~/npm/bin
and then do a test by running express
in the command line. This worked for me.
