I wanna install three packages in anaconda, but I face the following error.

 `Error: Could not install packages due to an OSError: [Errno 2] No such file or directory: 'c:\\programdata\\anaconda3\\lib\\site-packages\\numpy-1.20.1.dist-info\\METADATA'`.

I have changed `HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem@LongPathsEnabled` to `1`, but it does not still work. There are some similar problems with `pip` and some solutions are provided but I could not apply them. Is there any difference between the `pip\\METADA` error and `numpy\\METADATA` error?

I have basic knowledge and I would be thankful if someone can explain how to fix it with details. For example, some people suggested installing in another directory, but I do not know how to do this.
