使用pip安装mysqlclient时如何解决这个问题

Question

我正在尝试使用 django 并使用 mysql 作为数据库。我最初让它工作得很好，但我最近更改了用户帐户的名称，这就是一切都出错的地方。我已经使用 pip install mysqlclient 但下面的错误是我得到的。有没有办法以另一种方式安装 mysqlclient ？

我正在使用 django 的最新版本，并且我正在使用可视化代码。谢谢

Answer 1

去这个 站点 根据python版本下载包。并使用 pip install filename 就像我有 python 3.7.1 并下载红色圆圈中的文件并打开下载文件的终端并安装该文件，例如 pip install mysqlclient-1.4.4-cp37-cp37m-win32.whl

并在设置文件中

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'shoping_cart',
        'HOST': 'localhost',
        'USER': 'root',
        'PASSWORD':'',
        'PORT': '3306',

    }
}

对于 Linux 用户

首先，安装以下依赖项：

 sudo apt-get install python3.9-dev libmysqlclient-dev

# don't forget to change python version as per your virtual environment
# since I created my virtual environment with python3.9 that is why I
# have mentioned the same version above

然后安装mysqlclient：

 pip install mysqlclient
