Warning on import

[matteoferla]

The following warning happens:

$CONDAPREFIX/lib/python3.11/site-packages/_distutils_hack/__init__.py:31: UserWarning: Setuptools is replacing distutils. Support for replacing an already imported distutils is deprecated. In the future, this condition will fail. Register concerns at https://github.com/pypa/setuptools/issues/new?template=distutils-deprecation.yml
  warnings.warn(

This is due to the line from pip._internal.cli.main import main as pip_main which gets called like sig = pip_main(['install', path]).
The logic for not installing it as a child thread was to avoid the risk of being unable to.
