在heroku上部署python烧瓶应用程序给functools32提供了错误

Question

关于stackoverflow的第一个问题：D（因为我发现几乎所有的东西）。

我尝试部署我的Python应用的Heroku，但出现以下错误：

git push heroku master

在我的虚框一切工作正常，如果我做

pip install -r requirements.txt 

我试着不带以下果：

• 改变functools32版本
• 个从需求的文字，这让我意识到它删除functools是瓶中装饰:(

Answer 1

答案的依赖（多亏了注释）： 我不知道，我再次使用Python 2.7版（我我是一名初学者）在我的virtualenv。似乎使用functools在某处自动安装了functools32软件包，它将python 3中的functools移植到2. Heroku默认使用python 3，所以这就是为什么functools32可能不可用。

由于this post，我现在安装了一个python 3虚拟环境，移植了我从2到3移植的几件东西，所有东西都像魅力一样。

感谢davidism &昏暗指向我正确的方向。
