It looks like you don't have the MySQL library installed into your virtualenv. To fix that, start a Bash console in the virtualenv (use the link just underneath where you specified the env on the "Web" page) and then run:

pip install mysqlclient

Once you've done that, reload the web app (from the "Web" page again) and that error should disappear. If you're still seeing problems, make sure that you're looking at the error at the bottom of the error log.

Dear PythonAnywhere staff,

I'm getting the same error in using the pa_autoconfigure_django.py command.

When i tryed tu install the MySQL library with :

pip3 install mysqlclient

I got this result:

17:12 ~ $ pip3 install mysqlclient                                                                                                                                                                               
Looking in links: /usr/share/pip-wheels
Requirement already satisfied: mysqlclient in /usr/lib/python3.7/site-packages (1.3.13)

In my settings.py, in the DATABASE section , i'm using

DATABASES = {
    'default': {
                    'ENGINE' : 'django.db.backends.mysql',
                    ...
    }
}

Could you please give us the good configuration to deploy an app with :

Python 3.7 Django 2.2.7

Best regards,

pa_autoconfigure_django creates virtualenv for you and installs all the packages from your requirements.txt file. Why do you install mysqlclient?

fjl | 4352 posts | PythonAnywhere staff | Dec. 15, 2019, 10:08 p.m. | permalink

Thank's for your answer. I forgot the requirements.txt file.

It looks like you have set up your site to use a virtualenv. Have you installed mysqlclient into the virtualenv using pip?

giles | 11800 posts | PythonAnywhere staff | Aug. 20, 2020, 3:01 p.m. | permalink

yes, I installed , i am using python 2.7

deleted-user-9505601 | 1 post | Jan. 19, 2021, 10:45 p.m. | permalink

just to double check-- you did install into the proj2-virtualenv right? which seems like it is a python3.7 virtualenv
