i have set [[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" on .bashrc and have source ~/.rvm/scripts/rvm

anyone has the same problem or can help me? thx!!

Answer 1

you need to use wrappers, they will ensure proper ruby environment, since rvm 1.25 it is:

ls `gem env gemhome`/wrappers/unicorn_rails

also check example scripts for working with rvm and ruby environment => http://rvm.io/integration/init-d

Answer 2

i found that our server system has used ecryptfs ,so when user logout, the user dir will umount, then system can not found the rvm path in user dir and redirect to /.rvm ! thanks all to answer my question!
