Bug: Angular 4 spa + external lib using other node_modules libs on Windows

[xeax]

Then using relative "baseUrl": "." in tsconfig.json, somethere in internals generated webpack paths contains sometimes capital drive letter (i.e. G:\mc), sometimes not (i.e. g:\mc).

In Dev mode (ng serve --app=...) this caused error in browser:
TypeError: WEBPACK_IMPORTED_MODULE_1__angular_core.Version is not a constructor

But "ng build --prod --app=..." works fine.

Issue solved by using absolute paths (i.e. "baseUrl": "G:\mc") in tsconfig.json

PS: May be it is angular/cli or webpack bug.

Is it the same bug?
webpack/memory-fs#53

Could you provide a simplified reproduction in a Github repo so we could test this?

Could you try it with the latest version of Nx?
