"my_config.h" file not found when install mysql-python on osx 10.8
Solution 1:
brew install mysql
brew unlink mysql
brew install mysql-connector-c
sed -i -e 's/libs="$libs -l "/libs="$libs -lmysqlclient -lssl -lcrypto"/g' /usr/local/bin/mysql_config
pip install MySQL-python
brew unlink mysql-connector-c
brew link --overwrite mysql
Solution 2:
Works well on macOS High Sierra:
If you haven't already installed mysql: brew install mysql
brew unlink mysql
brew install mysql-connector-c
brew link --overwrite mysql
pip install MySQL-python
Solution 3:
please try:
brew install mysql-connector-c
pip install MySQL-python
Solution 4:
I used brew to install everything on Mac OS 10.14.2.
The other answers weren't working for me, when inside of a virtual environment (virtualenv) on Mojave. I followed Jofsey's instructions but got errors:

ld: library not found for -lssl
clang: error: linker command failed with exit code 1 (use -v to see invocation)
error: command 'cc' failed with exit status 1
So, after I ran those commands, I ran this as the final command and it worked:
sudo pip install MySQL-Python --global-option=build_ext --global-option="-I/usr/local/opt/openssl/include" --global-option="-L/usr/local/opt/openssl/lib"
Edit:
Another solution I found on GitHub, assuming you've already run brew install openssl (which avoids the need for CLI parameters and will prevent future SSL library errors):
export LIBRARY_PATH=$LIBRARY_PATH:/usr/local/opt/openssl/lib/
You can put the above in your ~/.bash_profile file and then run source ~/.bash_profile or if it's a virtual environment, you can find a way to run the export in the virtual environment shell and check the value in the virtual environment CLI with echo $LIBRARY_PATH. Once the $LIBRARY_PATH is set, you won't keep seeing these SSL library errors.
Solution 5:
My problem was that I was using MAMP's version of mysql and it didn't contain the dev headers. I downloaded the dmg of the official release and had it running in no time.
