Make sure you run commands with -v flag before pasting the output.

Steps to reproduce

Talked to @frostming offline, turns out it's because the shabang in __pypackages__/3.9/bin/pytest was not updated.

More context:

1. I was using 3.9.0 installed by pyenv
2. I setup pdm
3. I installed 3.9.7 and removed 3.9.0

$ cat __pypackages__/3.8/bin/pytest                                                                                                         
#!/Users/laike9m/.pyenv/versions/3.8.0/bin/python3.8
# -*- coding: utf-8 -*-
import re
import sys
from pytest import console_main
if __name__ == "__main__":
    sys.argv[0] = re.sub(r"(-script\.pyw|\.exe)?$", "", sys.argv[0])
    sys.exit(console_main()) 

Tried pdm update 3.8 then pdm update 3.8, can see "Updating executable scripts...", but shebang was not updated
