webpack: Global package: problem to resolve loaders

Hello,

I’m building a global npm package, but I get this error when using babel-loader:

Error: Cannot find module './node_modules/babel-loader/index.js'

The problem is webpack tries to resolve loaders from the target folder instead of my global package installation folder and of course I don’t want webpack to be installed in the target folder because it is unnecessary. How to tell webpack to use the babel-loader module from my global install ?

Thanks in advance for your help.
