Where does npm install packages?

Question

Can someone tell me where can I find the Node.js modules, which I installed using npm?

Answer 1

I was beginning to going mad searching the real configuration, so here is the all list of configuration files on linux:

• /etc/npmrc
• /home/youruser/.npmrc
• /root/.npmrc

on windows: - c/Program\ Files/nodejs/node_modules/npm/npmrc

Then in the file the prefix is configured:

prefix=/usr

The prefix is defaulted to /usr in linux, to ${APPDATA}\npm in windows

The node modules are under $prefix tree, and the path should contain $prefix/bin

There may be a problem :

• When you install globally, you use "sudo su" then the /root/.npmrc may be used!
• When you use locally without sudo: for your user its the /home/youruser/.npmrc.
• When your path doesn't represent your prefix
• When you use npm set -g prefix /usr it sets the /etc/npmrc global, but doesn't override the local

Here is all the informations that were missing to find what is configured where. Hope I have been exhaustive.
