Linux works correctly (Ubuntu with self-compiled Python 3.7.5)

$ python3.7 -m venv fooenv
$ . fooenv/bin/activate
(fooenv) $ python -c "import sys; print(sys.executable)"
/home/uranusjr/fooenv/bin/python
(fooenv) $ python -q
>>> import subprocess
>>> subprocess.check_output(['python', '-c', 'import sys; print(sys.executable)'])
b'/home/uranusjr/fooenv/bin/python\n'
