ImportError: dlopen(/Users/quzhen/.conda/envs/supply/lib/python3.6/site-packages/MySQLdb/_mysql.cpyt

问题

ImportError: dlopen(/Users/quzhen/.conda/envs/supply/lib/python3.6/site-packages/MySQLdb/_mysql.cpython-36m-darwin.so, 2): Library not loaded: @rpath/libmysqlclient.21.dylib
  Referenced from: /Users/quzhen/.conda/envs/supply/lib/python3.6/site-packages/MySQLdb/_mysql.cpython-36m-darwin.so
  Reason: image not found

解决

1. 从mysql安装路径的lib目录下将相应的依赖库建立软链接到/usr/local/lib/下

sudo ln -s /usr/local/mysql/lib/libmysqlclient.21.dylib /usr/lib/libmysqlclient.21.dylib

执行时报错：Operation not permitted
2. 这个只用进入恢复模式（重启时command+R），终端输入csrutil disable，回来就可以了！这样就不会Operation not permitted！
3. 再次执行sudo ln -s /usr/local/mysql/lib/libmysqlclient.21.dylib /usr/lib/libmysqlclient.21.dylib时有报ln: /usr/lib/libmysqlclient.21.dylib: Read-only file system
4. 进入root用户命令行sudo su -，执行：chmod 777 /usr/lib/libmysqlclient.21.dylib

=============================== 还是不行 ====================================
继续
5. 执行命令

sudo install_name_tool -change @rpath/libmysqlclient.21.dylib /usr/local/mysql/lib/libmysqlclient.21.dylib /Users/quzhen/.conda/envs/supply/lib/python3.6/site-packages/MySQLdb/_mysql.cpython-36m-darwin.so

成功解决！！！！ 奥利给~~~~

感谢这位救命的兄弟！！！！
