Error when compiling with webpack and babel-loader

I cannot seem to compile using the babel 6 loader and webpack. It's driving me mad. Has anyone else come across this problem? I cannot for the life of me see where I am screwing up. :)

Answer

According to the error it seems that redux is complaining about the stage option. It is probably because redux is still using Babel 5. This stage option has been removed from Babel 6.

But you shouldn't be running through babel those files. Hence something in your webpack.config.js should be wrong. Probably because your exclude field has an extra s.

Change:

excludes: /(node_modules|bower_components)/,
       ^

With:

exclude: /(node_modules|bower_components)/,
