安装python的mysqlclient==1.4.6报错

---

环境：
ubuntu18.04
python 3.7.2
Django 2.2

---

想要使用Django来操作MySQL，报错：

LookupError: No installed app with label 'admin'.

度娘搜索发现想要用Django来操作MySQL，还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
