macOS使用django安装mysqlclient遇到的问题(mysqlclient 1.3.3 or newer is required)

以后博客更新在:https://oldpan.me

有两个月没有碰django了，没想到一下从11.3升级到了2.0。django框架团队真的是很用心。

最近需要使用django搭建一个网站，使用的数据库是mysql。
mac电脑里面已经安装好了mysql-5.7-community。
之前使用的python和mysql的链接模块是Pymysql，使用django-11.3版本的时候没有需要问题。但是重新更新了django到2.0，下载好之前的配置后（requests），运行程序发现这个问题：

mysqlclient 1.3.3 or newer is required; you have 0.7.11.None

好吧，连之前的Pymysql都不能用了，于是进行安装mysqlclient。
使用pip进行安装：

pip install mysqlclient

并没有那么顺利，立马进行报错:

sh: mysql_config: command not found
Traceback (most recent call last):
  File "setup.py", line 15, in <module>
  ...

原来是没有找到mysql_config命令，那就进行添加吧：

(my-virtual-env-3.6.2) guoyanzongdeMacBook-Pro:Web_Assignment oldpan$ PATH="$PATH":/usr/local/mysql/bin

(my-virtual-env-3.6.2) guoyanzongdeMacBook-Pro:Web_Assignment oldpan$ mysql_config
Usage: /usr/local/mysql/bin/mysql_config [OPTIONS]
Compiler: Clang 8.1.0
Options:
        --cflags         [-I/usr/local/mysql/include ]
        --cxxflags       [-I/usr/local/mysql/include ]
        --include        [-I/usr/local/mysql/include]
        --libs           [-L/usr/local/mysql/lib -lmysqlclient ]
        --libs_r         [-L/usr/local/mysql/lib -lmysqlclient ]
        --plugindir      [/usr/local/mysql/lib/plugin]
        --socket         [/tmp/mysql.sock]
        --port           [0]
        --version        [5.7.19]
        --libmysqld-libs [-L/usr/local/mysql/lib -lmysqld ]
        --variable=VAR   VAR is one of:
                pkgincludedir [/usr/local/mysql/include]
                pkglibdir     [/usr/local/mysql/lib]
                plugindir     [/usr/local/mysql/lib/plugin]

好了，mysql_config能用了，接下来进行安装吧：

又遇到了问题，经查询是没有安装xcode工具：
打开mac的终端：

xcode-select --install

过了一两分钟后，安装好了，现在再进行安装mysqlclient：

(my-virtual-env-3.6.2) guoyanzongdeMacBook-Pro:Web_Assignment oldpan$ pip install mysqlclient-1.3.12.tar.gz 
Processing ./mysqlclient-1.3.12.tar.gz

终于安装好了！
