我正在尝试为Mac上的Python项目创建虚拟环境。
我创建了以下变量：
python3 -m venv venv
当我尝试运行时：
virtualenv venv
我收到以下错误：
zsh: /usr/local/bin/virtualenv: bad interpreter: /usr/local/opt/python3/bin/python3.6: no such file or directory
Using base prefix '/Users/<user_name>/miniconda3'

为解决此问题，我尝试了此post中建议的方法，该方法是强制重新安装virtualevn。他们建议进行以下修复：
pip install -U --force-reinstall virtualenv
但是，another post让我意识到，以这种方式使用pip可能会出现问题。因此，我将卸载命令调整为：
python3 -m pip install -U --force-reinstall virtualenv
但是错误仍然存在。我的直觉是我将不得不进入一些文件并更改路径。但是我不确定该走哪条路，应该走什么新路。
我还签出了this post，这使我想到了如何在计算机上安装各种版本的Python和pip。结果如下：
Machine-Name-2% which python
/Users/<user_name>/miniconda3/bin/python
