我正在尝试使用 LocalExecutor 作为 MySQL 作为我的后端来设置气流。但是在airflow initdb 期间我遇到了错误

所以我尝试使用命令安装 MySQLdb 安装 MySQL-python 时出错pip install MySQL-python

I have tried other way to install mysql-installation using pip 

```sudo apt-get install python-mysqldb```

【解决方案1】：

运行 pip install 'apache-airflow[mysql]'，它将安装 Airflow 所需的所有 MySQL 依赖项。
