circleci/ruby:2.3-node-browsers image had by default
ruby 2.3.6 installed. However, a recent update to this image, upgraded the ruby version to
2.3.7. Our deployment scheme requires the version to be strictly tied into
2.3.6 at the moment, however, this recent update to this image poses a problem to us.
An attempt to update this directly from the config.yml by installing rbenv and ruby2.3.6 fails. Errors with
ruby 2.3.6 is specified in Gemfile, but current version of ruby is 2.3.7
Any help is appreciated. Thanks!
