我有一个Django项目，我想将其部署在服务器上。但是我无法连接mysql。 我尝试了不同的替代方案，但无法解决这个问题。（我有kali linux操作系统）
这是我在安装mysqlclient时收到的错误：

Did you install mysqlclient?
您将需要安装一些额外的库。
请参考其项目描述：https://pypi.org/project/mysqlclient/
Linux
请注意，这是一个基本步骤。我不支持为所有环境构建完整的步骤。如果您看到一些错误，您应该自行修复它，或者在某些用户论坛中寻求支持。不要在问题跟踪器上提交问题。
您可能需要安装 Python 3 和 MySQL 开发头文件和库，如下所示：
$ sudo apt-get install python3-dev default-libmysqlclient-dev build-essential% sudo yum install python3-devel mysql-devel
然后你现在可以通过pip安装mysqlclient：
$ pip install mysqlclient
希望有帮助！
如 mysqlclient 的 PyPi 项目页面所述，您需要安装以下软件包：
对于 Debian / Ubuntu
$ sudo apt-get install python3-dev default-libmysqlclient-dev build-essential pkg-config
然后就可以通过pip安装mysqlclient了。
mysqlclient 的 PyPi 页面链接：
首先安装python 3.6.5，然后运行
pip install mysqlclient==1.3.12
sudo apt-get install python-dev default-libmysqlclient-dev
sudo apt-get install python3-dev
pip install mysqlclient
brew install mysql
pip install mysqlclient
第一步：安装MySQL客户端 可以直接通过pip使用命令安装MySQL客户端
pip install mysqlclient
