Try using django.db.backends.mysql instead.

如果我将 'ENGINE': 'mysql' 替换为 django.db.backends.mysql` 我会看到这个错误:

最佳答案

用 django.db.backends.mysql` 替换 'ENGINE': 'mysql' 是正确的。

现在，您必须更改:

DATABASES = {
    'default': {
        'ENGINE': 'mysql',
        'NAME': 'test',
        'DATABASE_USER': 'root',
        'DATABASE_PASSWORD': 'pass',
    }
}

到:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'test',
        'USER': 'root',
        'PASSWORD': 'pass',
    }
}
