Django + Bootstrap4引发错误：“需要mysqlclient 1.4.0或更高版本；您有0.10.0”

如何解决Django + Bootstrap4引发错误：“需要mysqlclient 1.4.0或更高版本；您有0.10.0”

我将Django 3.1.2与MysqL一起使用，它在数据库中正常工作。 但是后来我已经安装了Botstrap 4（点子安装bootstrap4）并将其加载到我的Tamplate {％load bootstrap4％}中，我得到了错误： django.core.exceptions.ImproperlyConfigured：需要MysqLclient 1.4.0或更高版本；您可以看到Bootstrap提高了0.10.0。

但是在我的venv中，我安装了模块MysqLclient版本2.0.1（不是0.10.0）。 （正如PyCharm向我展示的那样。） 基本python解释器的“ pip install MysqLclient”（在Conda中，不在venv中）没有帮助。

我不明白这一点。 以及引导程序之类的CSS / js库如何应用于数据库引擎？

如何解决？

解决方法

如果PyMySQL与mysqlclient一起安装，请删除它。之间有冲突。 （pip unistall pymysql）（如果存在于venv中。
