Ruby Passenger: no such file to load bundler

Question

I installed Phusion Passenger with Nginx, configured Nginx to point to the right directory, Then I ran webapp directory and this has downloaded the gemfiles, but it can't find the gems.

When I visit the site I get the standard Passenger error page which says:

Error message:
no such file to load -- bundler

Here's the full error: http://tinypic.com/view.php?pic=vpx36r&s=7

I've do a gem install bundler so I know bundler is installed, but I think it's looking in the wrong place for the gems.

It appears as if Passenger has installed ruby-enterprise-1.8.7 and it looks like 1.8 was already installed in this box.

gem env gives me the following:

  - RUBYGEMS VERSION: 1.4.2
  - RUBY VERSION: 1.8.7 (2009-12-24 patchlevel 248) [x86_64-linux]
  - INSTALLATION DIRECTORY: /opt/local/ruby-enterprise-1.8.7-2010.01/lib/ruby/gems/1.8
  - RUBY EXECUTABLE: /opt/local/ruby-enterprise-1.8.7-2010.01/bin/ruby
  - EXECUTABLE DIRECTORY: /opt/local/ruby-enterprise-1.8.7-2010.01/bin
  - RUBYGEMS PLATFORMS:
      - ruby
      - x86_64-linux
    - GEM PATHS:
      - /opt/local/ruby-enterprise-1.8.7-2010.01/lib/ruby/gems/1.8
 - /root/.gem/ruby/1.8
    - GEM CONFIGURATION:
       - :update_sources => true
       - :verbose => true
       - :benchmark => false
       - :backtrace => false
       - :bulk_threshold => 1000
    - REMOTE SOURCES:
       - http://rubygems.org/

From what I've read it appears to be a path issue, but I don't know what the best course of action is to fix it.

Here's the output of

which ruby:

/opt/local/ree/bin/ruby

which bundle:

/opt/local/ree/bin/bundle

I've run bundle install in that directory and it's given me:

Your bundle is complete! It was installed into ./vendor/bundle

Answer 1

it looks like you have some path issues (as you already stated). try to check why you have two different paths for your ruby installation.

I mean, according to your gem env output, you have some installation on

 /opt/local/ruby-enterprise-1.8.7-2010.01/

but you also have ruby and bunlder under

/opt/local/ree/

so, start from here to check if all the paths are correct and/or you haven't any double installations (well, it's just enough to check if your ENVs are coherent).

Another issue could be related to your nginx.conf, you should have something like this:

[...]
 http {
  passenger_root /your/path/to/passenger/gem;
  passenger_ruby /path/to/ruby;
  [...]
 }

UPDATE (just saw additional comments with nginx.conf):

as you can see, there's a problem with paths: you have two paths for ruby and gems installs:

/opt/local/ruby-enterprise....

and

/opt/local/ree

you should remove the latter (not phisically, just review ENVs to point to the first one)

EDIT: to change your env, you can append the following line to your /etc/bash.bashrc (or whaterver file is loaded from your shell by default):

PATH="/opt/local/ruby-enterprise-1.8.7-2010.01/bin:$PATH"

then logout and login, or for a quick test, launche this command from shell:

source /etc/bash.bashrc

now, retry to see what binary is used by default with:

which ruby
which gem
which rake
gem env
...

everything should have the /opt/local/ruby-enterprise-1.8.7-2010.01/ prefix (that's what is used from nginx and passenger configs).

UPDATE2: from the comments, it turned out that you have at least 3 ruby installs:

• ruby from your package manager in /usr/lib/ruby/ (are you using ubuntu linux?)
• a ruby in /opt/local/ree/
• a ruby in /opt/local/ruby-enterprise-....

at this point, the best thing to do is:

• uninstall all the rubys under /opt/local/ and all their gems

• uninstall (purge) system provided ruby packages (you don't need it)

• install and setup RVM: https://rvm.io

• re-install passenger using RVM: https://rvm.io/integration/passenger/
• fix nginx.conf to use passenger path and ruby
