Python manage.py 和 Mysql 突然不工作了(Python manage.py 在没有 Mysql 的情况下运行良好)

Question

突然之间，在尝试将React集成到Django中之后，按照本教程进行操作manage.pyDjango停止工作。每次我尝试运行服务器甚至尝试使用python manage.py找出可能的命令时，我都会收到以下错误：

(Python manage.py run fine before without Mysqldb)

During handling of the above exception, another exception occurred:

我已经尝试使用MySQL-python和mysqlclient安装MySQLldb，因为我使用的是 Python 3.x，我已经手动安装了 MySQL Python，但它安装在 Python 2 下......所以不太确定如何将其链接到Python 3

我什至尝试在教程之前git reset --hard并git clean撤消更改，但问题仍然存在。我只是不明白为什么错误会突然发生。我只想回到没有Mysqldb的情况下 manage.py 运行的美好时光

Answer 1

排序，我错误地删除

了

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

在 settings.py

添加行后，问题已修复
