Using RVM on FTP gives error “RVM is not a function…”

Question

I'm logging in to a FTP server and using our own servers version of ruby and gemset:

rvm use 1.9.2@'...'

But I get the error:

RVM is not a function, selecting rubies with 'rvm use...' will not work.

Do I add this: [[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" to my .bashrc ? Or what is the case here?

Thanks in advance for any help.

EDIT: I've found that this only occurs when I'm running a 'screen' session on the server. Why is this?

尝试：

source "$HOME/.rvm/scripts/rvm" && rvm use 1.9.2@gemset
