heroku: Gemfile.lock is required issue

Question

I have the following issue:

I'm trying to deploy my project on heroku but after i run

git push heroku master

I get the following:

git push heroku master -f

-----> Heroku receiving push 
-----> Ruby/Rails app detected
!
!     Gemfile.lock is required. Please run "bundle install" locally
!     and commit your Gemfile.lock.
!
!     Heroku push rejected, failed to compile Ruby/rails app
To git@heroku.com:*****.git
! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'git@heroku.com:*****.git'

I have run bundle install and bundle update for several times, i tried to delete Gemfile.lock from the repository and from my filesystem. But i still get the same message. Can anyone tell me what am i doing wrong?

The branch i'm trying to push is cloned from master.

Few things

1. Did you placed Gemfile.lock in git? if yes, is it lock (means updated? - you did several times just double check)
2. Just do bundle install on your local prompt.
3. now place Gemfile.lock
   • git add . or you can add only Gemfile.lock with this git add Gemfile.lock
   • git commit -m "commit message here"
   • git push

Now do git push heroku it should work.
