您好我已經開發了我的項目在本地的機器，但我已經轉移其生產成一臺服務器，我收到以下錯誤：Django的NodeNotFoundError執行syncdb時

python manage.py syncdb

以任何機會你創造一些對這些遷移過Django 1.8的早期版本？在我的一個項目中，我看到了一些類似的項目，其中遷移可以使用1.8.0，然後在1.8.2或更高版本中突然崩潰，然後突然再次開始工作。可能想要嘗試讓它在本地工作，然後在執行任何操作之前爲所有內容生成一個squash_migration。 – Paul

Paul感謝您的回覆。我想我已經找到了我的問題...我已經從生產中刪除了舊的遷移文件，然後再次運行它...所以現在它正在工作 – Paul85

恭喜您解決問題，對未來而言，很可能您的錯誤是由不同的在你的開發（新版本）和生產（舊版本）軟件包上的'django-registration'版本。爲了避免出現這樣的錯誤，請儘量保留帶有版本號列出的所有依賴關係的'requirements.txt'文件 - 以便能夠在相同版本中具有相同的依賴關係 - 當然還有virtualenv :) – Jerzyk

檢查您的Django的版本和升級你的依賴確保按要求安裝爲您的項目的所有依賴關係，然後如果檢查你的Python版本相同
