无法在 Mac 上使用 Django 设置 mysql

Question

I installed the recent version of MySQL for my mac (macOS 12(ARM, 64-bit), DMG Archive) and created a database called storefront. I'm working in a pipenv virtual environment and install mysqlclient. I've also updated my DATABASES settings to point to my new database in my settings.py file. DB Settings . But whenever I try to run the server I get an error. NameError: name '_mysql' is not defined Also at the top, (mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64e') I thought by installing the ARM version I wouldn't deal with this error. I wonder if it's pointing to the wrong file within my env despite adding the PATH to my.zshrc info. Is there a special way to point to the correct mysql or am I setting things up incorrectly? Here's my error message "

Error tell you, you have mysql macOs build for x86_64, but you should set up build for 'arm64e'.

here you can find both version for macOs: https://dev.mysql.com/downloads/mysql/

I install mySql many times on macos... and now i have mariaDb https://mariadb.com/kb/en/installing-mariadb-on-macos-using-homebrew/ For me it was easier to install
