Pip install mariadb mac

Question

I'm wanting to connect to a MariaDB database for a web app via Python but can't seem to install the mariadb package. I am running Mac with Python 3.7.9. Here is what I get when I try to run pip install mariadb is:

What I've tried:

1. New virtual environment (same issue)
2. Different Python version (same issue)
3. brew install mariadb-connector-c ( mariadb-connector-c 3.3.1 is already installed and up-to-date )
4. brew install libmariadb-dev & brew install libmariadb3 ( No available formula with the name "libmariadb-dev" & No available formula with the name "libmariadb3" )
5. brew install mariadb : installs but doesn't fix issue
6. Installing different but still relatively recent versions of mariadb : can do it but doesn't fix issue
7. Unlinking mariadb and linking mariadb-connector-c : can do it but doesn't fix issue

I've probably tried a few more things somewhere along the rabbit hole. Any suggestions welcome. Thanks.

Answer 1

If your XCode Command Line is out of date, it doesn't matter if you relink the mariadb connector-c or not. I couldn't make it work with: python 3.7, 3.8, 3.9 or the latest 3.10 versions. [just for the record, I use pyenv to support several python versions on my installation]

Going to AppStore and doing upgrade on XCode fixed the issue. After that, successfully installed:

pip install mariadb

into all of the above python versions with no issues at all. Interesting that I couldn't find any recommendation in MariaDB documentaion/requirements. What exactly prevented the pip installation, I still don't know.

Hopefully this will help someone to avoid some headache.
