• pip version:

  $ pip -V
  pip 23.3.1 from /home/vbrozik/dev/asa-cp-conv/.venv/lib/python3.10/site-packages/pip (python 3.10)
  

• Terminal/Shell: (powershell, pwsh, Windows Terminal, WSL etc.)
  Windows Terminal, bash inside WSL2

Description

After the package is installed its executables are not available to be executed directly from CLI. The usual location $VIRTUAL_ENV/bin/ does not contain executable wrappers used to start the package's scripts.

Expected behavior

After the installation the directory $VIRTUAL_ENV/bin/ should contain a wrapper for every program (like pip-date) with the executable right set and without any suffixes.

Actual Behaviour:

The directory $VIRTUAL_ENV/bin/ directly contains the package's Python scripts like pip-date.py without the executable access right set and with the .py suffix instead of usual wrappers used to start the program the normal way.

How to Reproduce

1. Create a venv, activate it and update its default packages.
2. Install pip-date using pip.
3. Check that pip-date cannot be executed.
4. Check that the bin directory inside the venv does not contain wrappers for the package's scripts.
