webpack: Compiled with warnings.

Desired functionality.

Mention any other details that might be useful.

ok, I fixed after 5 Hours but How ??

in generating one more module with defriend name like

the old component was
ng g c dial-edit-brand

I make new with this name
ng g c dial-ed-brand

but again I have the same problem after that inside my code I press enter sometimes and I change the lines of the code and voila this fix my problem

I thing this is vs code problem is cashing the files and is not delete some files

I hope this helps somebody

[atprana]

I wrongly casing the name of the import file with capital letter :
import { ValidateService } from './services/Validate.service';

after i change to small letter (the file name is in small letter ) :
import { ValidateService } from './services/validate.service';

the problem dissapear.

好意外，还真是字母大小写的问题，之前看的问题解答，都说是字母大写了，需要变为小写，而我这个这个是相反，但是确实也属于字母的大小写问题，解决了。

This problem will disappear when we replace the Capital case letters with small case letters in the import file path.
