Npm install do not install things in / usr / bin

Question

I am trying to install SailsJS with:

$ sudo npm install -g sails

It works, installs everything in / home / brunoluiz / npm / lib / node_modules / sails with the following log:

/home/brunoluiz/npm/bin/sails -> /home/brunoluiz/npm/lib/node_modules/sails/bin/sails.js

The problem is that you are trying to use sails: you launch sails new project, for example, and you will not find the sails. Having studied a little, I found that npm does not install modules in / usr / bin. Is there a reason for this? Some configuration?

The same thing happens with the Karma module.

I used nodejs from ppa, created a symbolic link for node and installed npm from the official install.sh script ( https://www.npmjs.org/install.sh ).

, npm /home/brunoluiz/npm prefix, , CLI, {prefix}/bin.

prefix /usr, /usr/local Unix (%APPDATA%/npm Windows).

{prefix}/bin $PATH, CLI .

prefix, :

npm get prefix

:

• /home/brunoluiz/npm/bin $PATH

• prefix , bin $PATH; :.

    npm set prefix /usr       # Ubuntu; CLI symlinks are placed in /usr/bin
    npm set prefix /usr/local # OSX; CLIs symlinks are placed in /usr/local/bin

, , {prefix}\bin .
