What is the problem? The username and password of database is correct.
PyMySql is not installed. Install it using pip or other available options:
pip install PyMySql
Unfortunately, peewee does not write `PyMySql1 module of python in its dependency list, so it should be installed separately.

How can I debug and get past this error?
Looks like updating the cli version solves the issue. I faced the same issue. Upgraded azure cli version using the below command. After the upgrade acr commands worked fine.
pip install --upgrade azure-cli

I have literally spent days on this, I did not face this issue when i was using the default django database engine, sqlite3.
I have tried doing this:
$python manage.py migrate sites
My SITE_ID setting is set to 1.
I tried removing the 'django.contrib.sites' thing from the INSTALLED_APPS setting, but that throws this error:

Any suggestions would be much appreciated.
Thanks.
uncomment the django.contrib.sites from installed apps
then
python manage.py migrate sites
python manage.py migrate
if you have few table in the database, drop the tables and then run this
I have a bash script that starts some python code, running on a RasPi under latest raspbian. It runs fine if I run it manually with sudo, but when it auto runs at boot I get a mysql error. The script is called from a line in /etc/rc.local
The script is
#!/bin/bash
/home/control/solar/v10_1/control.py >> '/home/control/solar/logs/control_X.X_start.log' 2>&1 &
echo "control started" >> '/home/control/solar/logs/control_X.X_start.log'
echo "UID is $UID , EUID is $EUID" >> '/home/control/solar/logs/control_X.X_start.log'
The output to the log after bootup is

I have made all the paths absolute, the UID is 0 in both cases, what can cause the difference in behaviour?

i have tried giving extensions to db name in settings.py but it didn't work.
Please suggest what to do.
Thanks !
Or you can do:
sudo apt-get install python-mysqldb
Do you have mysql installed in you virtual environment
Try
pip install MySQL-python
