Can't create '/go/to/file'

[Maxython]

I decided to experiment with installing packages without dependency. As a result, it was installed by pacman, but it was not installed in /usr/bin.
Example gcc installation:

~ $ pacman -Sdd gcc
warning: gcc-10.2.0-1 is up to date -- reinstalling

The program gcc is not installed. Install it by executing:
