django安装mysql驱动

　　django目前支持三种mysql驱动来进行mysql的链接

• 　　MySQLdb is a native driver that has been developed and supported for overa decade by Andy Dustman.
  
• 　　mysqlclient is a fork of MySQLdb which notably supports Python 3 andcan be used as a drop-in replacement for MySQLdb. At the time of this writing,this is the recommended choice for using MySQL with Django.
  
• 　　MySQL Connector/Python is a pure Python driver from Oracle that does notrequire the MySQL client library or any Python modules outside the standardlibrary.
  

　　mysqldb 目前不支持python3+，推荐使用mysqlclient
　　尝试了在pycharm上直接安装mysqlclient，报以下错误：OSError: mysql_config not found
　　在git上查阅安装步骤：
Prerequisites
　　You may need to install the Python and MySQL development headers and libraries like so:
　　sudo apt-get install python-dev libmysqlclient-dev # Debian / Ubuntu
　　sudo yum install python-devel mysql-devel # Red Hat / CentOS
　　On Windows, there are binary wheel you can install without MySQLConnector/C or MSVC.
Note on Python 3 : if you are using python3 then you need to install python3-dev using the following command :
　　sudo apt-get install python3-dev # debian / Ubuntu
　　sudo yum install python3-devel # Red Hat / CentOS
　　brew install mysql-connector-c # macOS (Homebrew)
Install from PyPI
　　pip install mysqlclient
　　因为我在mac上，使用的python3，故先执行命令：
　　brew install mysql-connector-c
　　然后再执行：
　　pip3 install mysqlclient
　　报如下错误：
　　Command "python setup.py egg_info" failed with error code 1 in /private/tmp/pip-build-m9v70gan/mysqlclient/
　　这个地方有点疑惑：使用pip3命令后，最终调用的是python，而不是python3
　　查看mysqlclient的源代码，发现根本原因还是因为没找到mysql_config，明白过来需要安装mysql，才能正常安装mysqlclient
　　Installed /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/mysqlclient-1.3.10-py3.6-macosx-10.6-intel.egg
