Cannot read property 'generateExportInfo' of undefined

Hey, I tried your plugin in a simple demo and it works well. Now I want to apply it to my team project which is much bigger. Then it failed and throw this error.

Here is the environment:
Node v8.11.3
webpack v4.17.1

Here are part of used plugins:

new webpack.optimize.ModuleConcatenationPlugin(),
new webpack.HashedModuleIdsPlugin(),
new WebpackDeepScopeAnalysisPlugin()

I can't figure out if it is my mistake or a bug of this plugin.

It seems that other plugin change the module that my plugin can not find some of them. I am going to debug with ModuleConcatenationPlugin.

[LeoEatle]

Yes. If I remove webpack.optimize.ModuleConcatenationPlugin, it works well.
My project is a multi-entry project. So I don't think ModuleConcatenationPlugin is helpful here.
Is multiple entry the reason why it failed?

Hi, @LeoEatle . I have published a pre-release version for this case. I want you to try it and I suppose it doesn't crash now.

Please upgrade to webpack-deep-scope-plugin@1.5.3-0.

[vincentdchan]

@LeoEatle Multi-entry can't make it crash. It crashed because ModuleConcatenationPlugin concats modules and my plugin can't find the analysis result of concatenation modules.

[LeoEatle]

OK, I tried webpack-deep-scope-plugin@1.5.3-0 and there's no error anymore. I think I can close this issue now.
Though, I don't find out any difference in size of the final bundle js files. I need to find out whether my code are free of these scope issues or the plugin is not working.

@LeoEatle Check if your babel/ts transpiled your code into UMD/CommonJS(ES6 module is required for optimization). And please use library that uses ES6 module(lodash-es instead of lodash)
