在我正在開發的應用程序引擎應用程序的本地實例中，我遇到了日誌系統的無限遞歸。不幸的是，由於問題出在日誌系統上，所以我看不到錯誤信息。 python'print'命令也不適用於谷歌應用程序引擎應用程序，因此我無法顯示任何有用的信息。谷歌應用程序引擎日誌系統中的無限遞歸
問題即使只是訪問網站根目錄也是可見的。
這似乎是一個導入問題，但除此之外，日誌記錄系統應該工作，而不是。
該網站的部署版本正在工作，這導致我想到可能的本地配置/系統問題。
我使用python 2.7.2和CURRENT_VERSION_ID = 1.1
這裏是錯誤的很長的堆棧跟蹤：

實際上，重命名應用程序的目錄並重新導入谷歌應用程序引擎啓動器與不同的端口解決了我的問題，但可能不是錯誤。
您是否可以發佈代碼摘錄？ –
實際上，main.py是一個包含數千行的巨大文件。我也不確定它是問題的根源，因爲遞歸是在日誌記錄模塊中進行的。這也似乎是我最近的變化與錯誤無關，因爲我已經撤消了它們，錯誤仍然存在。 – fstab
至少回覆您發佈的回溯表明，當您導入模塊時（從myapp.music_recommendation導入get_song_recommendations，get_song_recommendations_learning_data，learn_song，learn_song_from_video和從myapp.models.song導入歌曲），問題源於此。你還使用什麼Python版本和dev_appserver？ –
