ubuntu18桌面版 安装flask-mysqldb 编译不通过

Question

1.本人现在用的是Ubuntu18.04桌面版。在学习flask-mysqldb过程中出现了编译错误。
2.在提问本问题之前，百度谷歌无数，奈何不合我情，特向网友求助。
3.Failed building wheel for mysqlclient
Running setup.py clean for mysqlclient
Failed to build mysqlclient

Running setup.py install for mysqlclient ... error

1. 在安装 flask-script,flask-wtf等，都无误。本机上装的是Mysql8.0

这所有的安装学习都是在虚拟环境中进行的。

1. 求解决错误。

Answer 1

先安装 sudo apt-get install mysql-server libmysqld-dev 再安装 pip install flask-MySQLdb
