Heroku:错误推送Rails应用程序到Heroku,Heroku找不到Rails应用程序

Question

我试图将Rails应用程序推送到Heroku但是我经常遇到这个错误.

user$ git push heroku master
Initializing repository, done.
Counting objects: 158, done.
Delta compression using up to 4 threads.
Compressing objects: 100% (144/144), done.
Writing objects: 100% (158/158), 671.52 KiB | 160.00 KiB/s, done.

 !     Push rejected, failed to compile Ruby app

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

我研究了一些可能的解决方案,但是这些解决方案似乎都没有用.我试图销毁heroku应用程序,然后重新创建它,我尝试使用不同的ruby版本,但似乎也没有工作.

Heroku不支持2.1.1版

• https://devcenter.heroku.com/articles/ruby-support#supported-runtimes

您需要在Gemfile中指定不同的版本:

# Gemfile
source "https://rubygems.org"
ruby '2.1.4' # or other from link above
