I followed the instructions in this post around reinstalling setuptools and I have reinstalled Python from https://www.python.org/

which -a python gives

/Library/Frameworks/Python.framework/Versions/2.7/bin/python
/usr/local/bin/python
/usr/bin/python

The error seems to have occurred since installing MacOS 10.12.4 update

回答1:

Solved with this

brew install mysql
pip install MySQL-python

回答2:

If you still failed with something like "Failed building wheel for mysql-python", try

LDFLAGS=-L/usr/local/opt/openssl/lib pip install mysql-python

which works like a charm for me.

回答3:

If you are like me and installed mysql from source in mac, then forget who are suggest to use brew - your machine already has mysql-connector-c. If you did brew install mysql-connector-c, do brew uninstall mysql-connector-c and try pip install mysql-python again (Python 3).

This worked for me:

    brew install mysql@5.7
    brew link --force mysql@5.7

回答5:

This worked for me (macOS Mojave 10.14.2):

brew install mysql@5.7
brew link --force mysql@5.7
brew install mysql-client
LDFLAGS=-L/usr/local/opt/openssl/lib pip install mysql-python
