Hi, I use Win7 and download Winpython64-3.8.6.0dot.exe. When I run WinPython Command Prompt.exe, pass python and press Enter then get this error:

I have same problem with oryginal python-3.9.1-embed-amd64 when try running python.exe (from official page).

The important thing is that file winpython\python-3.8.6.amd64\python.exe from your project works fine (don't get any error). Any tips on what's the problem? I need access to pip (for install module) and to run py files in portable way.

Hmm, in env.bat I add set PYTHONPATH=%WINPYDIR%\lib and it works fine. Why this is not set by default in your project? Since it is portable, I shouldn't do anything to just execute some simple python code.

Btw, where are modules located by default if I use WinPython Command Prompt.exe? Where should I install them so that then the import will work?

Unfortunately I still have a problem for pip:

Any tips here? Looks like _socket is missing.

Windows 7 is not supported, may not work anymore
Meanwhile, I only find this that may be of help or not pypa/virtualenv#1069

From first post we see this:

  sys.path = [
    'C:\\Users\\Arek\\Desktop\\WPy64-3860\\python-3.8.6.amd64\\python38.zip',
    '.\\DLLs',
    '.\\lib',
    '',
  ]

I don't know why first path is absolute but 2 and 3 is relative, and relative to what? Solution is to manually set this two paths (DLL and lib) in PYTHONPATH variable. After that python.exe and pip works.

There still is some other problem with pip when I try install some package. Files (as cache) are downloaded and put in WinPython\python-3.9.0.amd64 with own subfolder, but after that I get error in console that file can't be installed. It's strange bacause some packages install without any problem:

# works
pip install pyside2
pip install flake8

# not works
pip install pyautogui
pip install pytweening

Can anyone confirm that installing the two abow packages (pyautogui and pytweening) works on the latest versions of WinPython? I wonder if it is the fault of the packages (not compatible with the latest WinPython version) or maybe just incompatibility with the operating system.

The solution is to manually put the files in the right places, but that's an extra step.
