無法在 Mac 上使用 Django 設置 mysql

Question

我為我的 mac（macOS 12（ARM，64 位），DMG Archive）安裝了最新版本的 MySQL，並創建了一個名為 storefront 的數據庫。 我在 pipenv 虛擬環境中工作並安裝 mysqlclient。 我還更新了我的 DATABASES 設置以指向我的 settings.py 文件中的新數據庫。 數據庫設置。 但是每當我嘗試運行服務器時，我都會收到錯誤消息。 NameError: name '_mysql' is not defined同樣在頂部， (mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64e')我想通過安裝 ARM 版本我不會處理這個錯誤。我想知道它是否指向我的環境中的錯誤文件，盡管將 PATH 添加到 my.zshrc 信息中。有沒有一種特殊的方法可以指向正確的 mysql 或者我是否設置不正確？這是我的錯誤消息“

Answer 1

錯誤告訴你，你有為 x86_64 構建的 mysql macOS，但你應該為“arm64e”設置構建。

在這里您可以找到適用於 macOS 的兩個版本： https://dev.mysql.com/downloads/mysql/

我在macos上多次安裝mySql ...現在我有mariaDb https://mariadb.com/kb/en/installing-mariadb-on-ma更容易
