Solution

  • If you workflow has Docker container, please stop the containers. Check with $docker ps and verify that all containers are in exited state.
  • Set the right Ruby version. Find out from the project repo Makefile, build scripts.
$ rbenv global 2.3.0

  • Update the bundler to same version as of Ruby.
$ gem install bundler
