在 Django 中配置不当的 MySQL

Question

settings.py：

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'OPTIONS': {
            'read_default_file': 'my.cnf',
        },
    }
}

我的.cnf：

[client]
database=fake
host=127.0.0.1
port=3306
user=fake
password=fake
default-character-set=utf8

这些文件位于我的 Django 项目的同一目录中。 （实际的my.cnf 具有真实凭据）。我有installed mysqlclient。但是，当我尝试 runserver 时，我得到了错误

我遗漏了哪些配置步骤？

这看起来可能是 this question 和 this one 的重复项

图书馆似乎不在它应该在的地方。从您之前的@​​987654323@ 看来，您将其安装在

/usr/local/mysql/

但 Django 期望它位于 /usr/lib/

像其他问题一样创建符号链接应该可以为您解决这个问题：

sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/local/lib/libmysqlclient.18.dylib

sudo ln -s /usr/local/mysql/lib /usr/local/mysql/lib/mysql
