I am using jruby-9.0.5.0 for my project. After setting up the server, I run cap production deploy:check, and I get:

DEBUG [3852050a] Running ~/.rvm/bin/rvm jruby-9.0.5.0@tagore do ruby --version as deployer@milan.jianshu.io

But when I log on to the system and run command ~/.rvm/bin/rvm jruby-9.0.5.0@tagore do ruby --version. It's all correct.

How could I fix this?

Thank you very much.

My server is running Ubuntu Server 12.04 with rvm latest installation. I am using capistrano 3.4 and capistrano-rvm 0.1.2
