How to install bem in ubuntu?

Question

Node.js

Good afternoon!
Installed from the repository: npm and nodejs.
Following the instructions, I ran:
$ echo 'export NODE_PATH="'$(npm root -g)'"'>> ~/.bashrc && . ~/.bashrc
$ sudo npm -g install bem
But running the command:
$
bem --help This error pops up:
/usr/bin/env: node: No such file or directory
Can you please write instructions on how to install bem on linux (ubuntu)?
