Django项目无法部署到Heroku

Question

我正在尝试部署Django项目。 首先，我收到了这个错误：

Counting objects: 74, done.
Delta compression using up to 2 threads.
Compressing objects: 100% (65/65), done.
Writing objects: 100% (74/74), 25.74 KiB | 0 bytes/s, done.
Total 74 (delta 24), reused 0 (delta 0)
remote: Compressing source files... done.
remote: Building source:
remote:
remote: -----> Failed to detect app matching https://codon-
buildpacks.s3.amazonaws.com/buildpacks/heroku/python.tgz buildpack
remote:        More info:

remote:

remote:
To https://git.heroku.com/nicoplus.git
 ! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'https://git.heroku.com/nicoplus.git'

然后，我设置了buildpack：     

heroku buildpacks:set heroku/python

但是，它仍然会抛出一个错误：     

remote: -----> Failed to detect app matching https://codon-buildpacks.s3.amazonaws.com/buildpacks/heroku/python.tgz buildpack

那么，这个问题的解决方案是什么？

PS：python是2.7.12

Answer 1

透过Heroku docs，我发现了这个：

“有许多额外的，不受支持的运行时可用。但是，我们只赞同并支持使用Python 3.6.1和2.7.13。”

我的猜测是使用2.7.12将其抛弃。
