[Django]-Virtualenv(python3.4), pip install mysqlclient error

This is probably due to your mysql_config being broken.

As of 2019, here is how to run smoothly pip install mysqlclient on MacOS:

brew info openssl and follow the commands at the bottom

  echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.zshrc
  export LDFLAGS="-L/usr/local/opt/openssl/lib"
  export CPPFLAGS="-I/usr/local/opt/openssl/include"

Other approaches:

• brew install/upgrade/reinstall mysql : did not fix the issue for me, but has the nice side effect to make sure your installation is clean.
• brew install mysql-connector-c : to make that work you have to unlink mysql, which ruins your setup and it did not fix the issue for me.

If you’re using Anaconda (which I highly suggest you) then run these two commands

conda install -c anaconda mysql-connector-python

and

conda install -c bioconda mysqlclient

1. Download the MySQL APT repository config tool (you can see more details here: http://dev.mysql.com/downloads/repo/apt/)

   wget http://dev.mysql.com/get/mysql-apt-config_0.7.3-1_all.deb
   

2. Install the MySQL APT repository config tool

   dpkg -i mysql-apt-config_0.7.3-1_all.deb
   

You will be asked to select product and version that you want to install. In the first step, select Server and next select either mysql-5.6 or mysql-5.7. Then click Apply.

3. Update APT

   apt-get update
   

4. Install the server

   sudo apt-get install mysql-community-server
   
   sudo apt-get install python-dev python3-dev
   sudo apt-get install libmysqlclient-dev
   pip install pymysql
   pip install mysqlclient
   

If you are using Python 2.x, and already have installed:

• MySQL Server
• Python Connector

Then the problem is when you run:

Windows:

(your environment) SomePath> pip install mysqlclient 

Mac OS:

$ pip install mysqlclient

Actually it is asking to install package for Python 3.x not 2.x. So it is throwing an error.

Solution is to run:

Windows:

(your environment) SomePath> pip install mysqlclient==1.3.9

Mac OS:

$ pip install mysqlclient==1.3.9

P.S The mysqlclient==1.3.9 version is the latest version for Python 2.x

For Ubuntu 18.04

sudo apt-get install python-dev python3-dev
sudo apt-get install libmysqlclient-dev
pip install pymysql
pip install mysqlclient

and setup

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql', 
        'NAME': 'DB_NAME',
        'USER': 'DB_USER',
        'PASSWORD': 'DB_PASSWORD',
        'HOST': 'localhost',   # Or an IP Address that your DB is hosted on
        'PORT': '3306',
    }
}

This worked for on Ubuntu 18.04

sudo apt-get install python3.6-dev 
sudo apt-get install mysql-client 
sudo apt-get install libsqlclient-dev 
sudo apt-get install libssl-dev

This worked for me on Python 3.12 and Ubuntu 22.04 WSL.

sudo apt-get install -y python3-dev
sudo apt-get install -y gcc default-libmysqlclient-dev pkg-config
pip install mysqlclient
