Discourse - Ruby 2.0 / Rails 4?

Question

I know this is not the right type of question for Stack Overflow (please forgive me), but I've spent hours trying to get Discourse to run on my machine. It was working before, but I upgraded to Ruby 2.0 and Rails 4 and now I simply can't get it working due to various errors (mounting NFS, Syck deprecated, TheRubyRacer not installing properly).

I tackled these one by one, and now when I SSH into vagrant it says cannot find the gemfile when I do bundle install. I think I may have altered something and it's not "SSH-ing" into the proper folder, but I did a lot of things based on what I googled / found on stackoverflow and am kind of stuck.

I know this is a very vague / poorly structured question, but I'm still new to programming and just wondering, does Discourse work with Ruby 2.0/Rails 4 and can someone point me in the right direction regarding how to tell if I somehow broke my SSH command?

Answer 1

Based on the Discourse source code and mainly based on the Gemfile/Gemfile.lock the rails version is Rails v3.2.12 and probably they are using Ruby 1.9.x

Edit 1
Based on Rails's Travis CI Builds it looks that rails supports ruby 2.0. I don't know if Rails 3.2.12 supports it - but my guess is that you should have little or no issue to run Discourse on Ruby 2.0.

Edit 2
Moreover it looks that Discourse Builds against Ruby 2.0 without problems.
