This tutorial has been updated with installation instruction for nodejs6.
To setup nodejs in ubuntu run following command
sudo curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash - sudo apt-get install -y nodejs
First command adds nodejs repo to software sources. This might be helpful in getting update automatically whenever you run
sudo apt-get-update. Second command is simply software installation command in ubuntu.
This will also install install npm. Now to install other node packages you can run command like
sudo npm install <package name>.
Locating node modules
node_modules may be hard to find. Here is how I found out:
I listed all global node modules with this command: `npm list -g –depth=0’. Output was like:
First line tells the location of node modules, which was
Avoid running npm as root
Recently I ran into problem where running npm with sudo command would do nothing and npm command without sudo would not install packages either. Thus I thought of changing owner of node modules to myself so that I need not use npm as root user. Turned out that; not running npm as root user is actually a good practice. So here is what can be done, second method is my preferred one as I don’t format my
/home folder when I format or fresh install newer ubuntu versions and I wont need to reinstall global node packages later.
option1: Change the permission to npm’s default directory
sudo chown -R `whoami` /usr/lib/node_modules/
option 2: Change npm’s default directory to another directory
# make a directory for global installations: mkdir ~/.npm-global # configure npm to use the new directory path: npm config set prefix '~/.npm-global' # Open or create a ~/.profile file and add this line: export PATH=~/.npm-global/bin:$PATH # Back on the command line, update your system variables: source ~/.profile
Now we no longer need to run npm with sudo command. This can be tested with following command:
npm install -g jshint
