Capistrano部署错误无法激活jruby-openssl-0.9.5-java

Question

I have developed a new Rails (4.1.4) app in JRuby (1.7.10) and I am trying to deploy it with Capistrano v3 on a remote vps. The error I am getting looks like:

end

It seems the root of the error is Thor gem. If I remove bundle folder inside shared directory then it installs all the gems. But it fails next time onwards. With 'remove_shared_bundle' task I tried to delete the bundle folder before before each deploy which worked. But then it would do a fresh installation every time which is time taking.

Is there a remedy for this issue?

Answer 1

I think this issue might be related to JRuby's default gems being unchangeable in 1.7.10 ... it has been fixed since, so the immediate thing is to try JRuby 1.7.15 (or at least 1.7.13)

I would than not declare gem 'jruby-openssl', '0.9.5' in the Gemfile (remove it completely) let JRuby use whatever it has available - wonder if there are any gem pulling it in, that could also help (if there's no gem pulling it into the bundle as a dependency) resolve it under 1.7.10.
