[New-bugs-announce] [issue38705] venv creation on macOS Catalina is failing

[Den Delimarsky]

New submission from Den Delimarsky <me at den.dev>:

I have a project, where I am working inside a virtual environment (on macOS Catalina). Inside said project, I am attempting to create a new virtual environment with:

venv.create(virtual_environment_directory, with_pip=True)

This, however, errors out:

  File "/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.7/lib/python3.7/runpy.py", line 193, in _run_module_as_main
    "__main__", mod_spec)
  File "/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.7/lib/python3.7/runpy.py", line 85, in _run_code
    exec(code, run_globals)

    CommandProcessor.validate(args, current_os)

    **kwargs).stdout
  File "/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.7/lib/python3.7/subprocess.py", line 487, in run
    output=stdout, stderr=stderr)
subprocess.CalledProcessError: Command '['/Users/user1/Documents//repos/adg/src/dtemp/bin/python3', '-Im', 'ensurepip', '--upgrade', '--default-pip']' died with <Signals.SIGABRT: 6>.

Seems like attempting to run this both from inside and outside the virtual environment results in the error.
