I am learning nodejs at the moment on Windows. Several modules are installed globally with npm.cmd, and nodejs failed to find the installed modules. Take jade for example,
npm install jade -g
Jade is installed in directory
"C:\Program Files (x86)\nodejs\node_modules", but the following code will fail with a
"Cannot find module 'jade'" error,
var jade = require('jade');
However, the code will run successfully when jade is locally installed (without -g option in npm). I don't want to use locally-installed modules, it's a waste of disk space for me. How can I make the globally-installed modules work on Windows?
Add an environment variable called
NODE_PATH and set it to
%USERPROFILE%\Application Data\npm\node_modules (Windows XP),
%AppData%\npm\node_modules (Windows 7/8/10), or wherever npm ends up installing the modules on your Windows flavor. To be done with it once and for all, add this as a System variable in the Advanced tab of the System Properties dialog (run
Quick solution in Windows 7+ is to just run:
rem for future setx NODE_PATH %AppData%\npm\node_modules rem for current session set NODE_PATH=%AppData%\npm\node_modules
It's worth to mention that
NODE_PATH is only used when importing modules in Node apps. When you want to use globally installed modules' binaries in your CLI you need to add it also to your
PATH, but without
node_modules part (for example
%AppData%\npm in Windows 7/8/10).
I'm pretty much new to node.js myself so I can be not entirely right but from my experience it's works this way:

if you are in the windows7 platform maybe you should change the NODE_PATH like this:
