升級到Django 1.11.4 ImportError

我試圖用Python 2.7.11將Django從1.10.7升級到1.11.4。我運行了pip install Django -U和python -c "import django; print django.get_version()"確認安裝了Django 1.11.4。但是，當我然後去運行測試時，我得到ImportError: No module named notmigrations。有人有建議嗎？升級到Django 1.11.4 ImportError

以下是完整的堆棧跟蹤：

你用遷移命令？ – Mattia

它看起來像你在你MIGRATION_MODULES設置使用notmigrations禁用遷移（如this post描述）。

在Django 1.9+中，您應該簡單地使用None而不是像'notmigrations'（release notes）這樣的假模塊名稱。

謝謝，但那只是中途。我在我的設置中找到了'MIGRATION_MODULES = DisableMigrations（）'行，並將其更改爲'MIGRATION_MODULES = None'，現在它給了我'TypeError：'NoneType'類型的參數不可迭代' – panatale1

我沒有說要設置'MIGRATION_MODULES = None'，我說要用'None'替換''notmigrations''。編輯你的'DisableMigrations'類來返回'None'而不是''notmigrations''。 – Alasdair

經過一個假期，然後不得不趕上趕上，我終於做到了這一點，它的工作。謝謝！！ – panatale1

Django的2.0，我創建的設置文件描述here與內容，如：

from settings import * 

class DisableMigrations(object): 
    def __contains__(self, item): 
     return True 

    def __getitem__(self, item): 
     return None 

MIGRATION_MODULES = DisableMigrations()

和運行我的測試測試新創建的設置
