PYTHON_PATH in PythonPlugin.cpp

[samuelgarcia]

I fight and finally manage to install this plugin under linux unbuntu 18.4 with python 3.6 with virtualenv+pip
I am trying now to do the same with ubuntu 20.4 and python3.8.

I am facing some difficulties see #29

The numpy can not be imported, the python path is wrong I think:

Could someone explain me theses lines in PythonPlugin.cpp ?

#ifdef _WIN32
    // set PYTHONPATH to avoid error described here: https://stackoverflow.com/questions/5694706/py-initialize-fails-unable-to-load-the-file-system-codec
    _putenv_s("PYTHONPATH", PYTHON_HOME_NAME "\\DLLs;" PYTHON_HOME_NAME "\\Lib;" PYTHON_HOME_NAME "\\Lib\\site-packages");
#else
    setenv("PYTHONPATH", PYTHON_PATH_NAME, 1);
#endif

Related question why do we have the code "PYTHON_HOME" and not "PYTHONHOME" ?

#ifdef _WIN32
        _putenv_s("PYTHON_HOME", PYTHON_HOME_NAME);
#else
        setenv("PYTHON_HOME", PYTHON_HOME_NAME, 1);
#endif

Am I missing something ?

I would do

#ifdef _WIN32
        _putenv_s("PYTHONHOME", PYTHON_HOME_NAME);
#else
        setenv("PYTHONHOME", PYTHON_HOME_NAME, 1);
#endif
