Python无法激活虚拟环境

Question

我在 Windows 10、Python 3.10.2。 以下是我为创建虚拟环境而运行的命令：

这是我的软件包版本：

virtualenv==16.7.5
virtualenvwrapper-win==1.2.6

1. 我安装了虚拟环境。

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.

然后我运行了这些命令：

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

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

以下是我为激活虚拟环境而运行的命令，但没有一个有效：

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
'.\Scripts\activate' is not recognized as an internal or external command,
operable program or batch file.

这里缺少什么？

谢谢。

Answer 1

使用 python 3.10.2 和 virtualenv 16.7.5 给我同样的错误。 看起来 virtualenv 16.7.5 对于 3.10.2 来说太旧了。 使用此命令升级您的 package，一切都会成功。

pip install --upgrade virtualenv

Answer 2

确保在 windows PATH 变量中有一个包含您的 python 安装和脚本子文件夹的条目，例如：C:\Program Files (x86)\Python36-32\ 和 C:\Program Files (x86)\PythonScript36-
使用 pip 安装 virtualenv 时，确保以管理员身份运行 cmd。 否则，安装过程中可能会出现 access denied 错误，导致 virtualenv 无法正常安装。 确保已正确安装 virtualenv。 检查 python 脚本子文件夹 - 必须存在名为 virtualenv.exe 的 .exe。 如果没有，卸载将 pip 卸载 virtualenv 并重新安装。
