npm
installs packages locally within your projects by default. You can also install packages globally (e.g. npm install -g <package>
) (useful for command-line apps). However the downside of this is that you need to be root (or use sudo
) to be able to install globally.
Here is a way to install packages globally for a given user.
mkdir "${HOME}/.npm-packages"
npm config set prefix "${HOME}/.npm-packages"
Add the following to your .bashrc
/.zshrc
:
NPM_PACKAGES="${HOME}/.npm-packages"
export PATH="$NPM_PACKAGES/bin:$PATH"
# Unset manpath so we can inherit from /etc/manpath via the `manpath` command
unset MANPATH # delete if you already modified MANPATH elsewhere in your config
export MANPATH="$NPM_PACKAGES/share/man:$(manpath)"
Check out npm-g_nosudo
for doing the above steps automagically
NOTE: If you are running macOS, the .bashrc
file may not yet exist, and the terminal will be obtaining its environment parameters from another file, such as .profile
or .bash_profile
. These files also reside in the user's home folder. In this case, simply adding the following line to them will instruct Terminal to also load the .bashrc
file:
source ~/.bashrc
