Open the webpack.optimize.ModuleConcatenationPlugin plug-in. The page cannot be accessed after the production environment is packaged. The error is as follows:
Uncaught TypeError: Cannot read property "call" of undefined

the introduction page of the plug-in is implicit and not very clear: https://webpack.js.org/plugin.
I hope that the friends who have this experience and solve the problem smoothly can give us some advice!
