Question

我已经通过以下链接浏览了Django教程。我已经在Mac上完成此操作，但是在Windows 10上遇到了问题：

在教程第2部分中，当涉及到创建新的超级用户时，它将失败。

如果在Mac上运行以下命令，则可以创建一个新的超级用户。当我在Windows上运行类似的命令时，它将失败。

我尝试在Windows上运行以下两项：

source venv/bin/activate
python manage.py createsuperuser

和

.\venv\Scripts\activate
py manage.py createsuperuser

包裹（点数列表）：

Package     Version
----------- -------
Django      2.2.6
docutils    0.15.2
pip         19.3.1
pycodestyle 2.5.0
pytz        2019.3
setuptools  41.4.0
sqlparse    0.3.0
wheel       0.33.6

存在db.sqlite3数据库，据我所知它具有合理的结构（有很多Django特定表）。

我希望创建一个新的超级用户，但获得以下输出：

Traceback (most recent call last):

django.core.exceptions.ImproperlyConfigured: The module in NAME could not be imported: django.contrib.auth.password_validation                .UserAttributeSimilarityValidator. Check your AUTH_PASSWORD_VALIDATORS setting.

Answer 1

您怀疑problem is in your password validation configuration是用反斜杠设置这些行的延续方式。

AUTH_PASSWORD_VALIDATORS = [
    {
        'NAME': 'django.contrib.auth.password_validation\
                .UserAttributeSimilarityValidator',
    },
    {
        'NAME': 'django.contrib.auth.password_validation\
                .MinimumLengthValidator',
    },
    {
        'NAME': 'django.contrib.auth.password_validation\
                .CommonPasswordValidator',
    },
    {
        'NAME': 'django.contrib.auth.password_validation\
                .NumericPasswordValidator',
    },
]

评估为

[
{'NAME': 'django.contrib.auth.password_validation                .UserAttributeSimilarityValidator'}, 
{'NAME': 'django.contrib.auth.password_validation                .MinimumLengthValidator'}, 
{'NAME': 'django.contrib.auth.password_validation                .CommonPasswordValidator'}, 
{'NAME': 'django.contrib.auth.password_validation                .NumericPasswordValidator'}
]

，没有django/contrib/auth/password_validation .py这样的模块。

如果相同的代码可以在macOS上运行，那么...好吧，很奇怪，这可能是文件名规范化的事情，但这仍然是问题所在。

解决方法自然是将其更改为

AUTH_PASSWORD_VALIDATORS = [
    {'NAME': 'django.contrib.auth.password_validation.UserAttributeSimilarityValidator'}, 
    {'NAME': 'django.contrib.auth.password_validation.MinimumLengthValidator'}, 
    {'NAME': 'django.contrib.auth.password_validation.CommonPasswordValidator'}, 
    {'NAME': 'django.contrib.auth.password_validation.NumericPasswordValidator'},
]

或者如果您希望这些行继续，

AUTH_PASSWORD_VALIDATORS = [
    {
        "NAME": "django.contrib.auth.password_validation."
        "UserAttributeSimilarityValidator"
    },
    {
        "NAME": "django.contrib.auth.password_validation."
        "MinimumLengthValidator"
    },
    {
        "NAME": "django.contrib.auth.password_validation."
        "CommonPasswordValidator"
    },
    {
        "NAME": "django.contrib.auth.password_validation."
        "NumericPasswordValidator"
    },
]

–即字符串文字背靠背，隐式地将它们串联在一起–即使我认为可读性较差，也同样有效。

python manage.py createsuperuser在Mac上有效，但在Windows上无效
