followed some posts and installed

brew install mysql-connector-c

But Still facing the issue.

For other solution tried the following solution,

https://stackoverflow.com/a/44338332/4107739

but couldn't find /usr/local/bin/mysql/bin/mysql_config

I'm running on MacOS, for Mysql I have XAMPP installed.

Answer 1

For python3 + mysql on mac. This worked for me:

1. brew install mysql-connector-c
2. edit mysql_config (locate it: which mysql_config )

Change the following in mysql_config:

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

To:

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

3. brew info openssl

4. and finally pip3 install mysqlclient

Answer 2

in XAMPP, the mysql_config would be somewhere in the below path. (based where you installed)

/Applications/XAMPP/xamppfiles/bin/mysql_config

Update the $PATH to include bin path

export PATH=$PATH:/Applications/XAMPP/xamppfiles/bin/

Run mysql_config, --libs and --libs_r should have -lmysqlclient -lssl -lcrypto ,

 <XAMPP_PATH>mysql_config | grep libs
        --libs           [-L/usr/local/Cellar/mysql/5.7.21/lib -lmysqlclient -lssl -lcrypto]
        --libs_r         [-L/usr/local/Cellar/mysql/5.7.21/lib -lmysqlclient -lssl -lcrypto]
        --libmysqld-libs [-L/usr/local/Cellar/mysql/5.7.21/lib -lmysqld -lssl -lcrypto]

if not, update the mysql_config to following values.

libs="-L$pkglibdir"
libs="$libs -lmysqlclient -lssl -lcrypto"

then run

pip3 install mysqlclient
