Answer 1

It seems like you're running a very old version of node and npm. It might need to be updated to install things correctly. I suggest you use the ppa. Please uninstall nodejs and then run this:

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

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

sudo apt-get install -y nodejs

and when that's done, run this again:

sudo npm install -g bower

Answer 2

Apart from the old version of node which should be upgraded, many (all?) versions of ubuntu install node executable under nodejs name. This creates many issues with with some processes that try to execute node code by invoking node command.

The reason for this is there is another package in ubuntu with the node binary. If you do not need the other package, you may want to create a symlink:

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