Mac pip install mysql-python unsuccessful

Question

I installed MySQL and Workbench from website. I have a django project whose requirements.txt:

Django==1.11.12
djangorestframework==3.8.2
django-cors-headers==2.2.0
drfdocs==0.0.11
mysql-python==1.2.5
django-rest-auth==0.9.3
django-allauth==0.35.0
nltk==3.2.5
django-extensions==2.0.7
pyparsing==2.2.0
pydot==1.2.4

When I run

pip install -r requirements.txt

I got an error mysql_config not found. To solve this I ran

PATH=$PATH:/usr/local/mysql/bin

It now throws

    _mysql.c:44:10: fatal error: 'my_config.h' file not found
    #include "my_config.h"
             ^~~~~~~~~~~~~
    1 error generated.
    error: command 'cc' failed with exit status 1

Why is this happening?

Answer 1

Installing of an older version of the MySQL worked for me:

brew remove mysql
brew install mysql@5.7
brew link --force mysql@5.7
pip install mysql-python

See:

• issue on the MySQLdb1 Github
• and this sof answer

Answer 2

Please, try:

CFLAGS=-Qunused-arguments CPPFLAGS=-Qunused-arguments pip install -r requirements.txt

If it does not work: First install mysql-connector-c

brew install mysql-connector-c 
pip install MySQL-python

If you are using Windows:

https://dev.mysql.com/downloads/connector/c/

You can also check what happend when you try install it with pip3.

UPDATE: If you have Linux: Please open the /usr/local/bin/mysql_config.

And then:

#Create options
Libs = "-L $ pkglibdir "
Libs = " $ libs   -l"

replace with:

#Create options
Libs = "- L $ pkglibdir"
Libs = "$ libs -lmysqlclient -lssl -lcrypto"

Save it and reinstall mysql-python.

pip uninstall mysql-python
pip install mysql-python

For Mac:

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

should be helpful.
