VirtualEnv 系统找不到指定的路径：'...Python3.6\\\\DLL'

Question

I am trying to downgrade python for tensorflow in a virtual env, the only way I found how to do this was to download Python3.6 and use the command

virtualenv -m TempEnv C:\Dev\Projects -p C:\Dev\Projects\Python3.6\python.exe

but I am getting the error:

FileNotFoundError: [WinError 3] The system cannot find the path specified: 'C:\\Dev\\Projects\\Python3.6\\DLLs'

Why is it looking for a DLL folder? this was not in the python 3.6 embedded download

Is there a better way to do this through virtual environments? I dont want to screw up my global python installation and libraries by downgrading everything

Thanks,

Answer 1

Had to download the windows installer, doesn't work with embedded version

Then the command line is simply virtualenv C:\\Dev\\Projects\\venv -p C:\\Dev\\Projects\\Python3.6\\python.exe

Answer 2

In my case using Windows and Python 3.10 embedded, I've just added the missing folder DLLs (letting it empty) in the respective Python directory and it works.

In your case you would have to build the new empty folder C:\\Dev\\Projects\\Python3.6\\DLLs and it should work
