Python无法激活虚拟环境

Question

I am on Windows 10, Python 3.10.2. Here are the commands that I ran to create the virtual environment:

Here are my versions for packages:

virtualenv==16.7.5
virtualenvwrapper-win==1.2.6

1. I installed the virtual environment.

D:\voice-cloning\real-time-voice-cloning>python -m pip install virtualenv
WARNING: Ignoring invalid distribution -ip (d:\python\lib\site-packages)
WARNING: Ignoring invalid distribution - (d:\python\lib\site-packages)

WARNING: You are using pip version 21.2.4; however, version 22.0.4 is available.
You should consider upgrading via the 'D:\python\python.exe -m pip install --upgrade pip' command.

Then I ran these commands:

D:\voice-cloning\real-time-voice-cloning>python -m virtualenv venv310

    if sysconfig._get_default_scheme() == "posix_local":

Here are the commands I ran for activating the virtual environment and none of them worked:

D:\voice-cloning\real-time-voice-cloning>venv310/scripts/activate
'venv310' is not recognized as an internal or external command,
operable program or batch file.

D:\voice-cloning\real-time-voice-cloning\venv310>.\Scripts\activate

What is missing here?

Thanks.

Answer 1

Using python 3.10.2 and virtualenv 16.7.5 gives me the same error. Looks like virtualenv 16.7.5 is too old for 3.10.2. Upgrade you package with this command and everything will work out.

pip install --upgrade virtualenv

Answer 2

Make sure that in the windows PATH variable there is an entry with your python installation and the scripts subfolder eg: C:\Program Files (x86)\Python36-32\ and C:\Program Files (x86)\Python36-32\Scripts
When using pip install virtualenv, make sure that you run cmd as administrator. Otherwise, there might an access denied error during installation and virtualenv will not be installed properly. Make sure that virtualenv has been installed correctly. Check in the python scripts subfolder - there must exist an.exe named virtualenv.exe. If not, uninstall will pip uninstall virtualenv and install again.
