Le't simprove this using:

if (typeof process.env.NODE_PATH !== undefined) {
 // Logic
}

I think we need the same change in webpack-cli and webpack itself, can you fix it? thank you

hm, from docs:

NODE_PATH is still supported, but is less necessary now that the Node.js ecosystem has settled on a convention for locating dependent modules. Sometimes deployments that rely on NODE_PATH show surprising behavior when people are unaware that NODE_PATH must be set. Sometimes a module's dependencies change, causing a different version (or even a different module) to be loaded as the NODE_PATH is searched.

And

Additionally, Node.js will search in the following list of GLOBAL_FOLDERS:

1: $HOME/.node_modules
2: $HOME/.node_libraries
3: $PREFIX/lib/node

Also paths on windows and linux are platform specific (and windows can has multiple paths separated by ;), so fix is not simple as I thought.

So I see two solutions here:

  1. Don't support it, but it can be paintful for some developers
  2. Fix our logic and handle all cases (not sure how we can handle $HOME and $PREFIX)

I am working on 2.

@snitin315 Found an easy solution, we should use it in webpack-cli/webpack

Also it should be after node_modules check
