python中django使用MySQL时出问题如何解决

我在使用MySQL作为django的数据库时

使用pip3 install mysqlclient时出现如下错误

Complete output from command python setup.py egg_info:
    /bin/sh: mysql_config: command not found
    Traceback (most recent call last):
      File "", line 1, in 
      File "/private/var/folders/td/b7z1_fb96hs0l5h0mb9prlk40000gn/T/pip-build-vo_xw7e8/mysqlclient/setup.py", line 17, in 
        metadata, options = get_config()
      File "/private/var/folders/td/b7z1_fb96hs0l5h0mb9prlk40000gn/T/pip-build-vo_xw7e8/mysqlclient/setup_posix.py", line 44, in get_config
        libs = mysql_config("libs_r")
      File "/private/var/folders/td/b7z1_fb96hs0l5h0mb9prlk40000gn/T/pip-build-vo_xw7e8/mysqlclient/setup_posix.py", line 26, in mysql_config
        raise EnvironmentError("%s not found" % (mysql_config.path,))
    OSError: mysql_config not found

解决办法是在terminal中输入如下的内容：

export PATH=$PATH:/usr/local/mysql/bin

即可
