ERROR: Failed building wheel for mysqlclient - mysql

Question

I'm unable to 'pip install mysqlclient', and every attempt returns the error: 'ERROR: Failed building wheel for mysqlclient'. For context, I'm running on macOS Mojave 10.14.5. The rest of this post assumes that both 'python==3.6' and 'virtualenv' are already downloaded. In addition, x-code command line tools are already installed (not that I think that matters).
The steps to this are (from command line):
'virtualenv ~/venv'
Output:
Using base prefix '/usr/local/Cellar/python/3.6.5_1/Frameworks/Python.framework/Versions/3.6'
New python executable in /Users/usr1/venv/bin/python3.6
Also creating executable in /Users/usr1/venv/bin/python
Installing setuptools, pip, wheel...done."
'source ~/venv/bin/activate'
'pip install mysqlclient'
So far, I've viewed and attempted everything on:
Failed building wheel for mysqlclient
"Failed building wheel for psycopg2" - MacOSX using virtualenv and pip
Failed building wheel for mysql-python

CONCLUSION: Ideally, I would like for 'pip' to simply install 'mysqlclient'. I would very much appreciate the help. Thanks in advance.

Answer 1

Only need to install dev version of python with:
sudo apt-get install python3-dev
ERROR: Failed building wheel for mysqlclient

Answer 2

Download mysqlclient.whl from this
Python Extension Package for Windows and install with pip install mysqlclient‑1.4.2‑cp36‑cp36m‑win_amd64.whl

Answer 3

When you are installing the mysqlclient Python library on your computer, you may encounter an error saying Failed building wheel for mysqlclient .
If you are using Debian/ Ubuntu then run the following commands:
sudo apt-get install python3-dev default-libmysqlclient-dev build-essential
If you are using Red Hat/ CentOS then run the following commands:
sudo yum install python3-devel mysql-devel
If the above commands running is finished then try to run this command again on your computer.
pip install mysqlclient
I hope everything works fine as you have expected.
Happy Coding :)
