git push heroku でエラーが出ます。

Question

###前提・実現したいこと
このエラーを直してデプロイをしたいです。
rails tutorialの11章が終わりGitのトピックブランチをmasterにマージし、続いてリモートリポジトリにプッシュし、Herokuにデプロイを行った際に、errorが起こりデプロイが成功しませんでした。

###該当のソースコード

Ruby on Rails
git push heroku

###試したこと
NoMethodError: undefined method action' for #<Rails::Application::Configuration:0x007fa5b17fa568> /tmp/build_dc7f1818c3e0158b52592e0f45ef3ade/vendor/bundle/ruby/2.2.0/gems/railties-5.0.0.1/lib/rails/railtie/configuration.rb:95:in method_missing' ここのエラーが原因だと思い類似のものを探してgem web console がinstallされているか確認しましたが、直りませんでした。

###補足
Heroku
cloud9
rails tでのエラーはありません。

Answer 1

理由はわかりませんが、Gemfile.lockを削除→Gemfileの gem 'rails', '~>5.0.0.1'に変更→bundle installをし、再度herokuにgit push heroku master をするこで直りました。
