python environment not used anymore

Since last update to Version 8.1.1722 (157) (on macOS 10.14.6) a python call within mvim doesn't use the python version from the environment mvim was started from but uses the system python. (before the update the python version from the environment was used)

• activate a python environment in a directory which has a different python version than the system python
  (- may check python --version in this directory)
• run mvim in this directory
• call vim command :!python --version

On my computer it returns the version number of the os-python not of the env-python

filed vim/vim issue #4856

Commencez par le contexte de lancement de mvim et la reproduction de :!python --version, puis consultez l’issue vim/vim #4856 ouverte pour obtenir le contexte associé. La tâche est terminée lorsqu’un mvim lancé dans un environnement activé invoque le Python de cet environnement plutôt que le Python du système sur la configuration macOS signalée.
