NameError: name '_mysql' is not defined after setting change to mysql

this worked for me:

add this to PATH:

export DYLD_LIBRARY_PATH="/usr/local/mysql/lib:$PATH"

This did the job for me! Just install libmysqlclient-dev (sudo apt-get install libmysqlclient-dev for Ubuntu). Sometimes, the lib files simply are missing even if you just installed mysql. :)

So, I'm answering my own question. Since my blog has database, I gave it a shot to make another project without db, start fresh.

What I noticed was there's a problem importing MySQLdb module(sub module of mysqlclient) with this traceback: Library not loaded: @rpath/libmysqlclient.21.dylib.

For browsing a few hours I realised that for some reason Mac security setting keeps this from being imported properly.

On mysqlclient library github I found one issue reporting the same as mine. It suggests I run cp -r /usr/local/mysql/lib/* /usr/local/lib/. After this I set settings.py for django.db.backends.mysql, ran python manage.py migrate and it worked. So for empty database, this could be a solution. Still struggling with database one though.

I use

• MacOS Catalina 10.15.6
• pyenv
