npm global install commands not found on zsh

问题

I just installed the package live-server using npm install -g live server

I checked and the package is currently installed at

/Users/username/.npm-global/lib/node_modules/live-server/live-server.js

However, when I try to run live-server from the command line I get the error

zsh: command not found: live-server

What do I need to do to be able to run live-server? I have oh-my-zsh installed and I'm worried that may be causing my issue. I understand it should have something to do with setting my PATH but I'm not sure what.

Running echo $PATH results in:

/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/opt/ImageMagick/bin:/Users/username/npm-global/bin:/Users/username/npm-global/bin:/Users/username/npm-global/lib

Here are some files in my root directory that may be relevant.

Thank you

回答1:

adding export PATH=$PATH:/Users/username/.npm-global/bin to .zshrc instead of .bashrc has solved my problem

回答2:

adding this to my ~/.zshrc fixed it for me

export PATH="$HOME/.npm-packages/bin:$PATH"

回答3:

Set it up this way to prevent further issues:

Install NVM to manage Node versions Install node with --lts so get the latest version Install NPM again latest version

After that set up the .zshrc file properly. Do not use the .bashrc if you use zshell, it has it's own config file, I think you already updated it.

Check the NPM page https://www.npmjs.com/package/live-server especially these parts:

Default options:
If a file ~/.live-server.json exists it will be loaded and used as default options for live-server on the command line. See "Usage from node" for option names.

Usage from node
var liveServer = require("live-server");
var params = ...
