Wheel file not used when installing mysql-python on MacOs

Installing mysql-python with pip succeeds, but with pipenv it fails.

I see that pip is installing from MySQL_python-1.2.5-cp27-cp27m-macosx_10_13_x86_64.whl. When installing via pipenv the wheel file is not used and it fails with:

Based on the log, your environment likely cannot build the wheel though… otherwise egg_info would not have failed 🤔

I suggest trying out if pipenv install mysqlclient works, and file any problems against it. It is a fork of MySQL-Python, but much better maintained and modern. The usage is completely identical.

Sorry about that. Was it previously automatically built on my mac and cached? I’m still learning python packaging. Thanks for explaining why it wasn’t working.
