"OSError: mysql_config not found" when trying to "pip install mysqlclient" - Django - pip

Question

I'm relatively new to Django, and Web Development in general.
I am trying to
pip install mysqlclient
in my
virtualenv -p python3
to hook up Django 2.0 to mySQL. However, I'm getting this error:
Collecting mysqlclient
Using cached mysqlclient-1.3.12.tar.gz
Complete output from command python setup.py egg_info:
/bin/sh: mysql_config: command not found
Traceback (most recent call last):

raise EnvironmentError("%s not found" % (mysql_config.path,))
OSError: mysql_config not found
----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/43/md5vpqrx0mx8627sq04slbz00000gn/T/pip-build-l8ea3vja/mysqlclient/
I have looked around for answers for hours, and yes, I have checked out this and this but nothing seems to be working.
Any help would be much appreciated!

Answer 1

the python package "mysqlclient" is depended on C system library to drive mysql connect，if you on ubuntu 16.4， just do as below：
sudo apt-get install libmysqlclient-dev
sudo pip install mysqlclient

Answer 2

If you get OSError: mysql_config not found when installing the mysqlclient Python package in macOS, then just do:
brew install mysql-client
export PATH="/usr/local/opt/mysql-client/bin:$PATH"
and retry.

Answer 3

You should start with cloning the mysqlclient repo:
git clone https://github.com/PyMySQL/mysqlclient-python
Then you will have to get mysql-connector-c. You can get it by doing:
brew install mysql-connector-c
Then open /usr/local/bin/mysql_config in a text editor.
From the Github issue:
There are lines in mysql_config like following:
# Create options
libs="-L$pkglibdir"
libs="$libs -l "
It should be:
#Create options
libs="-L$pkglibdir"
libs="$libs -lmysqlclient -lssl -lcrypto"
Save that file and change back to the directory where you downloaded the repo. Now open site.cfg file.
uncomment the line (remove the #)
#mysql_config = /usr/local/bin/mysql_config
Save that and run:
python3 setup.py install

Answer 4

For CentOS here's what made it work for me:
yum install gcc mysql-devel openssl-devel
#Install library explicitly, otherwise the python3 setup.py install will fail
pip3 install "mysqlclient==2.0.3" --global-option=build_ext --global-option="-L/usr/lib64/mysql/"
