Angular installation: TypeError: querystring.unescape is not a function

[Dejan Kropec]

Hi,

I have started to develop a application with Angular 5.

Anyway my files are compiled correctly but my app isn't working.

I got this error:

TypeError: querystring.unescape is not a function
    at getFilenameFromUrl (c:\php\gamesonline\node_modules\webpack-dev-middleware\lib\GetFilenameFromUrl.js:33:21)

Since querystring.unescape function is in node package i've installed fresh node 9.4.0. No changes, still get the same error.

But i've seen that in package-lock.json of my app source that angular is loading 3 different querystring (query-string, querystring-es3 and querystring) packages into my project. Since the last package querystring (^v0.20) doesn't have method unescape (only encode and decode methods), maybee not the right funcion get called in a wrong place. I think that could be the reason for the error? But I don't know how to correct this.

I think, maybee this error is a common thing with angular, does anybody have any solution for this issue, if not could please somebody more expirienced with angular5 discuse issue, related to my problem.
