How to *not* use rvm for a particular Nginx site?

[michaelfranzl]

I want to use system-installed Ruby 1.9.3 (Debian Wheezy) and gems for a particular Nginx site of mine, and ignore rvm completely. When I load the site, I get the error

It looks like Bundler could not find a gem. This is probably because your application is being run under a different environment than it's supposed to.

Then the error page lists various details. It has picked up the correct Ruby binary:

Ruby interpreter command
/usr/bin/ruby

However, the environment variables include all kinds of rvm settings:

rvm_bin_path = /usr/local/rvm/bin
GEM_HOME = /usr/local/rvm/gems/ruby-1.8.7-p374
IRBRC = /usr/local/rvm/rubies/ruby-1.8.7-p374/.irbrc
PATH = /usr/local/rvm/gems/ruby-1.8.7-p374/bin:/usr/local/rvm/gems/ruby-1.8.7-p374@global/bin:/usr/local/rvm/rubies/ruby-1.8.7-p374/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games:/usr/local/rvm/bin
etc.

The Passenger setting passenger_ruby /usr/bin/ruby1.9.1 does not help.

Any hints?

try this:

rvm mount /usr/bin/ruby -n system
rvm use ext-system
ls $GEM_HOME/wrappers/ruby

(you need RVM 1.25 for that)

Posting below the full output because it had errors. The output of ls was /usr/local/rvm/gems/ruby-1.8.7-p374/wrappers/ruby

hmm, it looks wrong, I will try it shortly, if you can wait hour or two I should have a fix for your problems.

[mpapis]

sorry it took some time but your problem should be fixed with rvm get head

[michaelfranzl]

Thanks for the fix. I won't be able to test it though, since I decided to run rvm as an unprivileged user (installed rvm as root user before). This way, the Ruby and Gem binaries of my OS are free of the rvm environment variables and run just fine.

[mpapis]

it works as far as I tested it so it should be good
