Webpack resolutions error with lodash and other modules

Question

Using yarn to generate webpack build throws multiple module resolution errors on Mac OSX only. Using npm works fine.

I believe the problem might be within webpack configuration to properly locate and load the modules.

Run 'yarn run build' on Mac OX.

After some debugging I found upgrading webpack and modules to latest stable version resolved this problem.
