Rails on Passenger not recognizing RVM

Question

I have shifted to ree using rvm by:

rvm use ree@mygemset

and installed kaminari gem through Gemfile and bundle install.

But Phusion passenger seems to still look for the gem in system default directory. It says:

Error message:
    Could not find kaminari-0.10.4 in any of the sources (Bundler::GemNotFound)

What do I missing? Rails need any specific configuration to recognize the current ruby version and gemset I am using??

You need to instruct Passenger to load RVM and then setup the environment for your gemset. The easiest way to go about this involves three steps:

1. Create a .rvmrc file : In the root of your rails project, create a file called .rvmrc that contains the RVM command you would use to load up your gemset. For example:

    rvm use ree@gemset 

2. Trust the .rvmrc file : Once you've deployed your new .rvmrc file to your server, change directories into your rails project. RVM should ask you if you want to trust your .rvmrc file; simply follow the instructions and type yes when asked. If the prompt does not appear, use the following command to trust your .rvmrc :

    rvm rvmrc trust 

   Note: If you wish to automatically trust all .rvmrc s, it is a simple matter of adding:

    rvm_trust_rvmrcs_flag=1 

   to your personal or system wide rvmrc ( ~/.rvmrc and /etc/rvmrc , respectively).

3. Instruct passenger to set up the RVM environment : Instruct passenger to load up RVM and use the gemset in your .rvmrc file by creating a new file in your Rails config directory called setup_load_paths.rb (so config/setup_load_paths.rb in all). The file should contain the contents of https://gist.github.com/870310 :

    if ENV['MY_RUBY_HOME'] && ENV['MY_RUBY_HOME'].include?('rvm') begin rvm_path = File.dirname(File.dirname(ENV['MY_RUBY_HOME'])) rvm_lib_path = File.join(rvm_path, 'lib') $LOAD_PATH.unshift rvm_lib_path require 'rvm' RVM.use_from_path! File.dirname(File.dirname(__FILE__)) rescue LoadError raise "RVM ruby lib is currently unavailable." end end # This assumes Bundler 1.0+ ENV['BUNDLE_GEMFILE'] = File.expand_path('../Gemfile', File.dirname(__FILE__)) require 'bundler/setup' 

   Now when you restart your app ( touch tmp/restart.txt ) you should be good to go.

You should note that Passenger can only run one version of Ruby at a time; if Passenger was set up under something other than ree, you will probably have to reinstall Passenger and/or redo the wrapper script it generates.

Just an additional note to step3 of the Marked (Broandon's) answer, because I didn't get my Passenger3 up and run by using those codes.

The error message is as below:

*** Phusion Passenger: no passenger_native_support.bundle found for the current Ruby interpreter. Compiling one...
# mkdir -p /Users/jerry/.rvm/gems/ruby-1.9.3-p194@xxx/gems/passenger-3.0.18/ext/ruby/ruby-1.9.3-x86_64-macosx
# cd /Users/jerry/.rvm/gems/ruby-1.9.3-p194@xxx/gems/passenger-3.0.18/ext/ruby/ruby-1.9.3-x86_64-macosx
Unable to locate the RVM path. Your RVM installation is probably too old. Please update it with 'rvm get head && rvm reload && rvm repair all'.

Referring to the message "Unable to locate the RVM path", I checked the RVM Documentation https://rvm.io/integration/passenger/

Edit config/setup_load_paths.rb to this:

if ENV['MY_RUBY_HOME'] && ENV['MY_RUBY_HOME'].include?('rvm')
  begin
    gems_path = ENV['MY_RUBY_HOME'].split(/@/)[0].sub(/rubies/,'gems')
    ENV['GEM_PATH'] = "#{gems_path}:#{gems_path}@global"
    require 'rvm'
    RVM.use_from_path! File.dirname(File.dirname(__FILE__))
  rescue LoadError
    raise "RVM gem is currently unavailable."
  end
end

# If you're not using Bundler at all, remove lines bellow
ENV['BUNDLE_GEMFILE'] = File.expand_path('../Gemfile', File.dirname(__FILE__))
require 'bundler/setup'

Problem solved!

Answer 3

I followed the suggested answer and it moved me forward but then I got an error message:

RVM - Ruby integration was extracted to a separate gem, it should be installed by default >with RVM, remove the $LOAD_PATH.unshift line and all should be fine again. Visit https://rvm.io/integration/passenger for more details. (RuntimeError)

Passenger now have a gem. My mistake was not installing it in the ruby version and gemset I was using. Once I did that - everything worked sweet.

删除Passenger 4的config/setup_load_paths.rb文件。不需要。
