Question

我是Windows用户，并且非常熟悉django和数据库。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。我尝试通过下载所有必需的软件包输入pip install -r requirements.txt。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或什至在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（来自版本：0.0.1、0.0.2）找不到mysql == 8.0.13 **的匹配发行版

因此，即使经过多次尝试，我也找不到解决方案，所以当我输入 'py manage.py runserver'或'python manage.py runserver'，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。

Answer 1

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，您需要从其网站https://dev.mysql.com/downloads/mysql/下载MySQL（或使用软件包管理器，例如Chocolatey。

您需要通过pip安装的Python库是mysqlclient。

无法在Windows上安装正确版本的mysql（8.0.13）
