Answer 1

After extensive troubleshooting, I found that the brew install mysql-connector-c just does not work.

The problem stems from the system not being able to identify that mysql_config is installed (which is what mysql-connector-c essentially does). Homebrew's method (open for argument) of installing the mysql-connector-c in its /Cellar/ and creating a symlink to the /usr/local/bin/ directory seems to be causing problems as Python tries to follow the symlink.

To resolve the issue I performed the following:

1. brew uninstall mysql-connector-c
2. download/install MacOS X MySQL Connector/C from Oracle's MySQL site
   • note: just download the .dmg, no need to be complicated here...
3. restart MacOS Terminal (or iTerm2) for good measure

4. which mysql_config

   • you should see the correct path /usr/local/bin/mysql/bin/mysql_config

5. activate virtualenv (if applicable)

6. pip install mysqlclient

There may be other ways to still use Homebrew, but this was the most straightforward solution I found.

Note that the mysqlclient GitHub README.md also states that the C-developer headers for Python3 are needed. I assume that mysql-connector-c includes those; however, should you run into more issues, you might also install the Xcode Developer CI Tools for good measure.

xcode-select --install

They include the C compiler and other developer utilities from Apple. Read more here.

This worked for me:

1. brew install mysql-connector-c

2. edit mysql_config (locate it: which mysql_config)

correct this in mysql_config:

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

It shoud be:

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

4. brew info openssl
5. and finally pip3 install mysqlclient

Answer 3

For Python 2.7 on specific programs:

1. sudo chown -R $USER /Library/Python/2.7
2. brew install mysql@5.7
3. brew install mysql-connector-c
4. brew link --overwrite mysql@5.7
5. echo 'export PATH="/usr/local/opt/mysql@5.7/bin:$PATH"' >> ~/.bash_profile
6. sed -i -e 's/libs="$libs -l "/libs="$libs -lmysqlclient -lssl -lcrypto"/g' /usr/local/bin/mysql_config
7. pip install MySql-python

This solved all issues I was having running a program that ran on Python 2.7 on and older version of MySql

I'm just getting started with python and had similar problems when trying to do pip3 install mysqlclient to connect Django to MySQL 8.0.19 but on my case it is on a macOS Catalina 10.15.5 with Python 3.8. I also tried brew install mysql-connector-c but it also gave me a lot of trouble. Here's how I manage to make it work.

1. brew reinstall mysql
2. brew install mysql-client

• Note: After installing mysql-client I got the following messages in the terminal which I just followed and got all to work.
• mysql-client is keg-only, which means it was not symlinked into /usr/local, because it conflicts with mysql (which contains client libraries). If you need to have mysql-client first in your PATH run:

3. echo 'export PATH="/usr/local/opt/mysql-client/bin:$PATH"' >> ~/.zshrc

• For compilers to find mysql-client you may need to set:

4. export LDFLAGS="-L/usr/local/opt/mysql-client/lib"
5. export CPPFLAGS="-I/usr/local/opt/mysql-client/include"

• Then I just tried to install mysqlclient again and it worked. I also tried it on a python .venv environment and it worked as well using:

6. pip3 install mysqlclient

Hope this works as it did for me today. Regards, Alfredo

Answer 5

I resolved this installing libmysqlclient-dev first:

sudo apt-get install libmysqlclient-dev

Hope it works for you.

Personally I recommend using pymysql instead of using mysqlclient. You can install pymysql with:

pip install pymysql

And you might edit your SQLAlchemy URL to:

mysql+pymysql://username:passwd@hostname/database
