Answer 1 · 2023-05-06T10:50:33.000Z

it seems mysql 8.0.33 issue -> Homebrew/homebrew-core#130258

WORKAROUND -> if you use Django:

Use Oracle MySQL Connector/Python
(https://docs.djangoproject.com/en/4.2/ref/databases/#mysql-db-api-drivers

1)Download https://dev.mysql.com/downloads/connector/python/
2)DATABASES = { 'default': { 'ENGINE': 'mysql.connector.django', 'NAME': '<name_db>', 'USER': '<user_db>', 'PASSWORD': '<pass_db>', 'HOST': 'localhost', 'PORT': '3306', } }

It seems MySQL bug. They break mysql_config often.

Answer 3 · 2023-05-07T07:20:03.000Z

I've tried almost all available solutions on google and failed.
M2 Ventura is eating my 3hours..

Answer 4 · 2023-05-07T08:12:57.000Z

$ export MYSQLCLIENT_LDFLAGS=$(pkg-config --libs mysqlclient)
$ export MYSQLCLIENT_CFLAGS=$(pkg-config --cflags mysqlclient)
$ pip install mysqlclient

@methane , Adding those variables worked for me. Thanks!

Answer 6 · 2023-05-08T08:44:39.000Z

@methane Thanks a lot! It works for me.

Answer 7 · 2023-05-08T14:52:43.000Z

Thanks @methane, it works for me also!

Answer 8 · 2023-05-08T20:50:10.000Z

@methane
got message "zsh: command not found: pkg-config"
what could be the problem?

Answer 9 · 2023-05-09T01:32:06.000Z

Do Google. I don't know your environment.

Answer 10 · 2023-05-09T07:20:41.000Z

@2twenity

mac os global environment run: ->
brew install pkg-config

in your virtualenv or other environment ->

export MYSQLCLIENT_LDFLAGS=$(pkg-config --libs mysqlclient)
export MYSQLCLIENT_CFLAGS=$(pkg-config --cflags mysqlclient)
pip install mysqlclient

@giuseppenovielli This worked! Thank you

Answer 12 · 2023-05-13T17:51:31.000Z

This worked, thank you so much!!

Answer 13 · 2023-05-19T05:02:20.000Z

I have released 2.2.0rc1 that uses pkg-config instead of broken mysql_config.
Please try it.
https://pypi.org/project/mysqlclient/2.2.0rc1/

Answer 14 · 2023-05-26T12:41:57.000Z

2.2.0rc1 is fixed, following @methane previews post:

# ensure pkg-config is installed
brew install pkg-config

# Follow https://pypi.org/project/mysqlclient/2.2.0rc1/ "macOS (Homebrew)" section instructions
export PKG_CONFIG_PATH="/opt/homebrew/opt/mysql-client/lib/pkgconfig"

# 2.2.0rc1 installation works
pip install --no-cache mysqlclient==2.2.0rc1

Answer 15 · 2023-06-23T00:29:10.000Z

To have a complete solution in linux... try this

apt install pkg-config
export MYSQLCLIENT_LDFLAGS=$(pkg-config --libs mysqlclient)
export MYSQLCLIENT_CFLAGS=$(pkg-config --cflags mysqlclient)
pip install mysqlclient --no-cache-dir

or as stated in the official page

apt install -y pkg-config                                  
export MYSQLCLIENT_CFLAGS=`pkg-config mysqlclient --cflags`
export MYSQLCLIENT_LDFLAGS=`pkg-config mysqlclient --libs` 
pip3 install mysqlclient --no-cache-dir

Answer 16 · 2023-06-23T01:59:46.000Z

No need to set MYSQLCLIENT_CFLAGS and MYSQLCLIENT_LDFLAGS if pkg-config works.
