在 Python3.8 中创建虚拟环境时出错

Question

virtualenv myvirtualenv

我是 Python 虚拟环境的新手。我正在关注本教程https://uoa-eresearch.github.io/eresearch-cookbook/recipe/2014/11/26/python-virtual-env/

但卡在第 3 步

我得到的错误：

Thanks in advance

Answer 1

您不需要在 python 3.3 或更高版本中使用virtualenv 包。这些版本中有一个内置的解决方案。 只需运行以下命令： python -m venv myvirtualenv 它将创建一个名为“myvirtualenv”的新虚拟环境。

Answer 2

试试下面的-

virtualenv -p python3 myvirtualenv
