angular: Warning: There are multiple modules with names that only differ in casing. This can lead to unexpected behavior when compiling on a filesystem with other case-semantic.

 

>PROBLEM

The compilation returns the follwing warning message:

  Warning: There are multiple modules with names that only differ in casing.
  This can lead to unexpected behavior when compiling on a filesystem with other case-semantic.
  Use equal casing. Compare these module identifiers:

>SOLUTION

Two things to check:

1. If working on Windows, files hasn't case sensitive approach.
So, make sure that the file pointed by the warning message matches case.
If not, remember that it doesn't help renaming the file. It is necessary to rename the file to a different one and then rename it back using the name with the right case.

2. Check the import referred by the error message that it is pointing to the path with different case.
It works on Windows but not on *nix or Mac.
Follow by the images.

Fixed: switched from "_ConfigDb"  to  "_ConfigDB"
