Bug
What is the current behavior?
On my local machine I noticed no issues with the webpack upgrade, but travis fails each time since upgrade.
Travis cannot complete npm run test command, throws the following error
21 06 2017 20:16:31.514:ERROR [config]: Invalid config file!
TypeError: webpack.optimize.ModuleConcatenationPlugin is not a constructor
at Object. (/home/travis/build/…/webpack.prod.config.babel.js:91:3)
at Module._compile (module.js:569:30)
at loader (/home/travis/build/…/node_modules/babel-register/lib/node.js:144:5)
If the current behavior is a bug, please provide the steps to reproduce.
Updated to Webpack 3 and add the following snippet to webpack config
// Webpack 3 Scope Hoisting
new webpack.optimize.ModuleConcatenationPlugin(),
What is the expected behavior?
Travis not to fail
If this is a feature request, what is motivation or use case for changing the behavior?
