I got a similar post on Stack Overflow : can't pip install mysql-python

That is for Ubuntu. But still I tried to install python-dev as suggested in the answer of that post using pip and got the following error :

Some-MacBook-Air:~ itssuyog$ sudo pip install python-dev

Thanx in advance!!

Answer 1

python-dev is the wrong python-dev; it seems some rogue Chineeze took the name and created a package that installs a backdoor.

Real python-dev is a development package for Debian/Ubuntu installable with apt . You don't need it in MacOS. If you have done brew install python (or python3 ) you should already have all necessary development files.

Try installing mysql-connector:

brew install mysql-connector-c
