!     Gemfile.lock is required. Please run "bundle install" locally
!     and commit your Gemfile.lock.

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.

Answer 1

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.

Answer 2

On your development machine run rm -rf .bundle && bundle install && git add Gemfile.lock && git commit -m "Added Gemfile.lock" Then deploy.

Answer 3

Most likely your Gemfile.lock is not committed to your repository. Use git st and ensure that the Gemfile.lock is committed; check your .gitignore file to make sure that you're not accidentally ignoring it.

Answer 4

Check your .gitignore file, if you put Gemfile.lock there, get rid of that line and run this commands:

git add Gemfile.lock
git commit -m "Added Gemfile.lock"
git push
git push heroku

Answer 5

It's telling you that you need to push a Gemfile.lock - that's how Heroku knows what versions of gems your application is using. After bundling locally, commit the resultant Gemfile.lock then push the application to Heroku.

Answer 6

I had this problem, I forgot the bundle install

After it and git & Heroku everything went OK
Don't forget either the git remote

after writing your code the sequence would be :

bundle install
heroku create
git init
git add *
git remote
git commit -a -m "First init"
git push heroku master 

I think it's complete

Answer 7

Just remove the /Gemfile.lock from your .gitignore
