Heroku：將Rails應用程序推送到Heroku時出錯，Heroku找不到Rails應用程序

Question

我正試圖將Rails應用程序推送到Heroku，但是我不斷收到此錯誤。

Taimurs-MacBook-Pro:taimurknaziri.com taimurknaziri$ git push heroku master 
Initializing repository, done. 
Counting objects: 158, done. 
Delta compression using up to 4 threads.

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

我有研究一些可能的解決方案懸停在S.O上，但是沒有一個似乎工作。我試圖摧毀heroku應用程序然後重新創建它，我嘗試使用不同的ruby版本，但似乎也沒有工作。

Heroku的不支持版本2.1.1

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

你需要在你的Gemfile指定不同的版本：

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