无法激活Python中的虚拟环境

Question

我在Windows 10，Python3.10.2。下面是我运行的创建虚拟环境的命令：

以下是我的软件包版本：

virtualenv==16.7.5
virtualenvwrapper-win==1.2.6

1. I安装了虚拟环境.

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.

然后我运行了以下命令：

D:\voice-cloning\real-time-voice-cloning>python -m virtualenv venv310
D:\python\lib\site-packages\virtualenv.py:24: DeprecationWarning: The distutils package is deprecated and slated for removal in Python 3.12. Use setuptools or check PEP 632 for potential alternatives

  import distutils.sysconfig

    fix_local_scheme(home_dir, symlink)

    if sysconfig._get_default_scheme() == "posix_local":
AttributeError: module 'sysconfig' has no attribute '_get_default_scheme'. Did you mean: 'get_default_scheme'?

下面是我运行的用于激活虚拟环境的命令，但这些命令都没有工作：

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>python venv310/scripts/activate

D:\voice-cloning\real-time-voice-cloning\venv310>.\Scripts\activate
'.\Scripts\activate' is not recognized as an internal or external command,

这里少了什么？

谢谢。

确保在windows路径变量中有一个带有python安装和脚本子文件夹的条目，例如: C:\Program (x86)\Python36-32\和C:\Program (X86)\Python36.32\ scripts

当使用时，请确保您以管理员身份运行cmd。否则，可能会在安装过程中出现访问拒绝错误，并且将无法正确安装virtualenv。确保virtualenv已正确安装。签入python子文件夹-必须存在一个名为.exe的virtualenv.exe。否则，卸载将触发卸载virtualenv并再次安装。
