Why doesn't NPM install globally?

Question

Node.js

Installed NodeJS. With it, npm got up, both work globally from the console.
But when trying to install modules globally
, "npm install -g bower"
Puts everything in the user's folder as it should, but the module is not globally available, what could be the problem?
Cmd from under admin
Win 8.1

Answer 1

I have a directory with global modules under win 7:
It needs to be added to the PATH variable.
Under win 8.1, most likely the path is the same.

Answer 2

You need to add the directory with the node binaries to PATH

Answer 3

I had a similar problem, it turned out that the Path variable was referring to another user's folder. I removed everything superfluous from there and reinstalled the node, during installation everything is registered there by itself.
