我正在try 将python从3.6升级到3.8.我成功地使用了virtualenv/wrapper(虽然只有一个环境，没有Bell、whistles或Hook)，但升级并不顺利.我删除了所有内容，并试图重新开始.我正在try 创建一个mkvirtualenv test的新环境，现在我得到了一个错误:
virtualenv: error: unrecognized arguments: --no-site-packages之后，它给出了一个关于如何调用virtualenv的建议，这让我相信virtualenvwrapper是有效的，但我错过了一些东西.
以下是我的详细信息:

- 试图安装VirtualVWrapper时，它说是4.8.4版，但在线文档说是5版.十、
