Issues with urllib3 install using `mysqlclient` database backend

[paul-english]

I can't seem to get localshop to mirror a proper version of urllib3.

I can install it once no problem, but any additional attempt to install it fails. The latest version at this time is 1.18, but after I do a first initial install I get the following release record,

which has no information stored in it.

I also get this error in the celery worker which I expect is the issue:

After the first pip install a second one yields the following from my local machine:

pip install -i https://<localshop_install>/simple/ -U --force-reinstall urllib3
