I try to upload app and run on heroku source files are below. https://github.com/utahub/django_attend-managing-app/tree/heroku_check

with command 

git push heroku heroku_check:master

but even thought runtime.txt exists in Root Dir, Heroku does not detect defauld language.

remote: Compressing source files... done.
remote: Building source:
remote:
remote:  !     No default language could be detected for this app.
remote:                         HINT: This occurs when Heroku cannot detect the buildpack to use for this application automatically.
remote:                         See https://devcenter.heroku.com/articles/buildpacks
remote:
remote:  !     Push failed
remote: Verifying deploy...
remote:
remote: !       Push rejected to uta-attend-managing-app.
remote:

I stacked with this problem for 2 days. Please tell me why this is happened.

Thankyou in advance.

  • Note : with buildpack command, it successed, but is there anyway to deploy without buildpack command ? there are no qiita article which use buildpack, so i think something with my app looks wrong. I want to figure out i –  Feb 03 '18 at 03:23

Someone asked this question already: Can't push to the heroku

CodeWizard's solution:

Read this doc which will explain to you what to do.
https://devcenter.heroku.com/articles/buildpacks

Setting a buildpack on an application

You can change the buildpack used by an application by setting the buildpack value.
When the application is next pushed, the new buildpack will be used.

$ heroku buildpacks:set heroku/python

Buildpack set. Next release on random-app-1234 will use heroku/php.
Run git push heroku master to create a new release using this buildpack.

This is whay its not working for you since you did not set it up.

... When the application is next pushed, the new buildpack will be used.

You may also specify a buildpack during app creation:

$ heroku create myapp --buildpack heroku/python
