安装python的mysqlclient==1.4.6报错

安装python的mysqlclient==1.4.6报错

---

环境：
ubuntu18.04
python 3.6.8
Django 2.0

---

想要使用Django来操作MySQL，需要安装一个驱动程序。在Python3中，选择用mysqlclient做驱动。

 

安装mysqlclient出现报错：

解决方案：

1.先安装 客户端程序：

sudo apt install -y mysql-client

2.基于python安装mysqlclient需要依次安装以下库:

sudo apt-get install libmysqlclient-dev
sudo apt install libssl-dev 
sudo apt install libcrypto++-dev 

3.使用pip安装mysqlclient

sudo pip3 install mysqlclient
或者在虚拟环境中用如下命令安装指定版本
(cootuu) root@VM-0-6-ubuntu:~# pip install mysqlclient==1.4.6
