Heroku Rails 部署问题

Question

I'm trying to push my rails app to deployment via Heroku and whenever i do, i'm getting thrown this error:

            Detected buildpacks: Ruby,Node.js
            See https://devcenter.heroku.com/articles/buildpacks#buildpack-detect-order
-----> Ruby app detected

       Running: BUNDLE_WITHOUT='development:test' BUNDLE_PATH=vendor/bundle BUNDLE_BIN=vendor/bundle/bin BUNDLE_DEPLOYMENT=1 bundle install -j4
       /usr/bin/env: ‘jruby’: No such file or directory
       Bundler Output: /usr/bin/env: ‘jruby’: No such file or directory
 !
 !     Failed to install gems via Bundler.

 !     Push rejected, failed to compile Ruby app.

Jruby seems to be playing into this somewhere but i just can't figure it out. Any help would be appreciated.

Answer 1

Answer has been solved as of today. The problem was that somewhere along the line, jruby got included in the list of gem dependencies and snowballed into everything else. In order to fix the problem, I needed to remove all instances of jruby from all folders within the app and it was able to compile properly and deploy.
