Upgraded to Ubuntu 16.04 now MySQL-python dependencies are broken

I had this issue on updating to stretch. To fix it I updated my requirements.txt:

mysqlclient==1.4.2.post1

So either update that manually or pip install --upgrade mysqlclient

I had the same issue. I uninstalled and reinstalled MySQL-python:

pip uninstall MySQL-python
pip install MySQL-python

I ended up finding the solution to my problems with pip install --no-binary MySQL-python MySQL-python as stated in this thread : Python's MySQLdb can’t find libmysqlclient.dylib with Homebrewed MySQL

Thank for Largaroth. If you use mysqlclient on Ubuntu 16.04 and have error: ImportError: libmysqlclient.so.18: cannot open shared object file: No such file or directory

You can fix:

sudo -H pip uninstall mysqlclient

sudo -H pip install --no-binary mysqlclient mysqlclient
