Requiring different gems in the capfile based on deploy environment

[vanderkerkoff]

Hello everyone

capistrano 3.4

rails 4.2.1

Here's the situation

Staging server ubuntu14 running nginx with passenger and RVM, multiple apps, multiple rubies.

Production server ubuntu14 running nginx with passenger, multiple apps, one ruby.

As I'm requiring capistrano/rvm in the Capfile, to make the deploy work in the staging environment, the deploy will similarly fail in the production environment, as rvm isn't installed in the production environment.

Production deploy spits out this

[6a908a85] Running ~/.rvm/bin/rvm version as user@rmachinename

DEBUG [6a908a85] Command: ~/.rvm/bin/rvm version

DEBUG [6a908a85] bash: /home/user/.rvm/bin/rvm: No such file or directory

(Backtrace restricted to imported tasks)

cap aborted!

SSHKit::Runner::ExecuteError: Exception while executing as user@rmachinename: rvm exit status: 127

rvm stdout: bash: /home/user/.rvm/bin/rvm: No such file or directory

rvm stderr: Nothing written

Is there any way to get around this that anyone can think of?

I don't really want to have to install rvm on the production system, or remove it from the staging system.

Multiple Capfiles?  Conditionals in the Capfile?

Anyone got any ideas?

sorry if this has been documented previously, I haven't been able to find anything as of yet.
