在heroku上部署python燒瓶應用程序給functools32提供了錯誤

關於stackoverflow的第一個問題：D（因爲我發現幾乎所有的東西）。在heroku上部署python燒瓶應用程序給functools32提供了錯誤

我嘗試部署我的Python應用的Heroku，但出現以下錯誤：

在我的虛框一切工作正常，如果我做

pip install -r requirements.txt

我試着不帶以下果：

改變functools32版本
個從需求的文字，這讓我意識到它刪除functools是瓶中裝飾:(

上面的回溯說'這個backport僅適用於Python 2.7'，但是你使用的python3已經內置了'functools'模塊.AFAIK'functools'不是燒瓶依賴項，但你可能已經使用過在您的燒瓶應用程序中的2.7回程，可能是這個問題！ – dimmg

'functools32'不是Flask對任何受支持的Python版本的依賴。如果你不直接在'requirements.txt'中包含它，Pip會告訴你依賴關係來自哪裏。這種依賴從何而來？ – davidism

答案的依賴（多虧了註釋）：我不知道，我再次使用Python 2.7版（我我是一名初學者）在我的virtualenv。似乎使用functools在某處自動安裝了functools32軟件包，它將python 3中的functools移植到2. Heroku默認使用python 3，所以這就是爲什麼functools32可能不可用。

由於this post，我現在安裝了一個python 3虛擬環境，移植了我從2到3移植的幾件東西，所有東西都像魅力一樣。

感謝davidism &昏暗指向我正確的方向。
