无法在Windows上安装正确版本的mysql（8.0.13）

Question

我是Windows用户，对Django和数据库非常陌生。 我当前的小组项目需要使用django和mysql。 我的队友（macOS用户）已经建立了一个django网站，而我试图通过在virtualenv上运行它来运行该网站。 我尝试通过键入pip install -r requirements.txt下载所有必需的软件包。 虽然，它下载了大多数软件包，但不允许我安装mysql == 8.0.13。 我尝试了其他方法，例如pip install mysql==8.0.13 ，甚至尝试在ubuntu bash上尝试。

但是，我总是收到此消息。

(virtualenv) C:\\Users\\ed>pip install mysql==8.0.13

收集mysql == 8.0.13找不到满足mysql == 8.0.13要求的版本（从版本：0.0.1、0.0.2开始）未找到与mysql == 8.0.13匹配的发行版**

因此，即使经过多次尝试，我也找不到解决方案，所以当我只键入'py manage.py runserver'或'python manage.py runserver'时，结果显示如下。

(virtualenv) C:\\kim....\\projectsite>py manage.py runserver

我在这个问题上困扰了很长时间，甚至仍然无法运行manage.py。 请帮助我解决这个问题，并提出任何好的解决方案。 感谢您的阅读。

您将MySQL数据库与用于连接它的Python库混淆了。

pip仅安装Python库。 要安装MySQL本身，您需要从其站点下载它： https : //dev.mysql.com/downloads/mysql/ （或使用程序包管理器，例如Chocolatey。

您需要通过pip安装的Python库是mysqlclient 。
