在我的虚拟盒子上,如果我这样做,一切都很好

pip install -r requirements.txt

更改functools32版本
从需求文本中删除functools,这让我意识到这是装饰器对Flask的依赖:(

回答(感谢评论): 我没有意识到我在我的virtualenv中使用了python 2.7(同样,我是个初学者)。似乎在某处使用functools自动安装了functools32包,该包将functools从python 3移植到2。Heroku默认使用python 3,因此functools32可能不可用。

我现在安装了一个python 3虚拟环境,这要归功于 this post ,将我的帽子从2个端口移植到3个端口,一切都像一个符咒。
