Hello Alex!
I have reinstalled everyhting on our server (Linux Centos7) and added MySql
database as well but now when i run the superset db upgrade command i get the
error i have posted below
It seems is not able to find MySQLdb module (i have had a look at the blogs
and it seems there is a problem to install this and other packages for MySql
with Python 3.x)
Were you able to install it in your environment?
Thanks&Regards
Matteo
