Error when installing Phusion Passenger "Could not find passenger (= 0) amongst [] (Gem::LoadError)"

Question

I'm following these directions to install Rails 3 on my WHM/cPanel VPS. The only change I'm making is to use Ruby 1.9.3 and Rails 3.2.3 However when I get to the command to run "passenger-install-apache2-module" I'm having issues. First, due to PATH issues I need to go into the correct directory to run the command. More importantly, once I execute the command I get the error "Could not find passenger (>= 0) amongst [] (Gem::LoadError)" (Full error below). The square brackets are empty, so I verified that the gems were there via "gem list --local" and passenger is listed. System Specs: CENTOS 5.8, WHM 11.32, VPS with root access Full error: ``` /home/tekruby/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/site_ruby/1.9.1/rubygems/dependency.rb:247:in `to_specs': Could not find passenger (>= 0) amongst [] (Gem::LoadError) from /home/tekruby/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/site_ruby/1.9.1/rubygems/dependency.rb:256:in `to_spec' from /home/tekruby/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/site_ruby/…

Accepted Answer

You are doing it inside a rails app path, try:

```
cd ..
```

and then

```
passenger-install-apache2-module
```

I guess it works
