Failed to deploy redmine to HEROKU due to Gemfile.lock nonexistence


I had this particular error upon pushing/deploying to Heroku

Counting objects: 92259, done. Delta compression using up to 4 threads. Compressing objects: 100% (19977/19977), done. Writing objects: 48% (45054/92259), 13.63 MiB | 103 KiB/s Writing objects: 100% (92259/92259), 23.82 MiB | 87 KiB/s, done. Total 92259 (delta 72165), reused 90569 (delta 70774) -----> Ruby/NoLockfile app detected ! ! Gemfile.lock required. Please check it in. ! ! Push rejected, failed to compile Ruby/NoLockfile app To git@heroku.com:xiruki-task.git ! [remote rejected] master -> master (pre-receive hook declined) error: failed to push some refs to 'git@heroku.com:xiruki-task.git'

I've tried to remove the Gemfile.lock and bundle install again but no luck.

Any workarounds will be appreciated.


run bundle install and that will generate your gemfile.lock. Then commit it and deploy to heroku
