It seems that you are using a very old version of node and npm . You may need an update for proper installation. I suggest you use ppa. Remove nodejs and then run this:

 curl -sL https://deb.nodesource.com/setup | sudo bash -

This will add node.js ppa to your repositories, so it will be updated like any other program. Now you just need to install it:

 sudo apt-get install -y nodejs

and when this is done, run it again:

 sudo npm install -g bower

source

Besides the old version of node that needs to be updated, many (all?) Versions of ubuntu install the node executable under the name nodejs . This creates a lot of problems with some processes that try to execute node code by invoking the node command.

The reason for this is another ubuntu binary package with node . If you do not need another package, you can create a symbolic link:

 $ whereis nodejs nodejs: /whatever/path/nodejs $ cd /whatever/path $ sudo ln -s nodejs node
+1
source

Run the following commands that you can easily install using angularJS

  • sudo apt-get install nodejs
  • List item
  • sudo apt-get install -y python-software-properties
  • sudo add-apt-repository ppa: chris-lea / node.js
  • Sudo apt-get update
  • npm config set prefix / usr / local

If you want to install bower, use the following commands

  1. sudo npm install -g bower
  2. bower install angular # 1.3.0-beta.13
