使用命令“virtualenv venv”创建 Python 虚拟环境时出错

Question

当我使用命令virtualenv venv创建Python虚拟环境时，出现如下错误：

D:\Flask>virtualenv venv
Using base prefix 'd:\\APP\\python'
New python executable in D:\Flask\venv\Scripts\python.exe
Installing setuptools, pip, wheel...
  Complete output from command D:\Flask\venv\Scripts\python.exe - setuptools pip wheel:

    % (cmd_desc, proc.returncode))
OSError: Command D:\Flask\venv\Scripts\python.exe - setuptools pip wheel failed with error code 1

我搜索了它，但没有找到解决方案。有人知道怎么处理吗？

使用python -m venv path/to/your/venv创建一个虚拟环境，然后用path/to/your/venv/Scripts/activate.bat激活它（deactivate退出venv）

示例：

python -m venv test
test\Scripts\activate.bat
(test) deactivate
