Unable to reference global installed module issues in Windows environment

In the node project, it is often necessary to install some dependent packages, usually we take a global installation, to reduce the trouble of some package repeat installation.

However, after the global installation can not be used, it may be that you NODE_PATH did not set or incorrect results.

Solution Solutions

So, what is it NODE_PATH ?

NODE_PATHIs the environment variable that node provides for the module to find the path. For the node module loading strategy, you can refer to here.

So, how do you configure NODE_PATH it?

Simply add a new named variable to the environment variable with the value of NODE_PATH npm 's installation directory, for example:

C:\Users\XX\AppData\Roaming\npm\node_modules
