The --deployment flag requires a Gemfile.lock

I have spent couple of hours but unable to solve this problem.

When I try to deploy my local rails app to production server using capistrano I get the below error:

The --deployment flag requires a Gemfile.lock. Please make sure you have checked your Gemfile.lock into version control before deploying.

Any idea on how to solve this?

My rails application folder is under version control using Git. I have pushed the local git repo to github and the Gemfile.lock is there on github. So it is under version control. However capistrano continues to give the same error.

Solution

  • Make sure there is nothing in the releases folder that is not a release. See this comment on a bundler issue for more details.

    This blogpost titled Capistrano Deployment Trouble explains the same issue.

    EDIT TO INCLUDE CONCLUSION FROM DISCUSSION IN COMMENTS

    The deploy_to param was not set to an absolute path; hence capistrano wasn't able to find the folder to deploy, causing this error message.
