Question

I installed the passenger gem, but it didn’t work with my old nginx. So I am trying to install nginx from the passenger script.

I do $ sudo ./bin/passenger-install-nginx-module, which gives

 * rack... not found
 * To install rack:
   Please install RubyGems first, then run /home/dbadmin/.rvm/wrappers/ruby-1.9.3-p286@rails-3.1.1/gem install rack

Although the rack gem is in fact installed. Anyway, I do

$ /home/dbadmin/.rvm/wrappers/ruby-1.9.3-p286@rails-3.1.1/gem install rack
Successfully installed rack-1.4.1
1 gem installed
Installing ri documentation for rack-1.4.1...
Installing RDoc documentation for rack-1.4.1...

After this, $ sudo ./bin/passenger-install-nginx-module again says that * rack... not found.

What might be happening?

If you’re going to use sudo with rvm, you need to use rvmsudo – because sudo doesn’t run root’s profile (i.e. doesn’t load RVM) when it changes to the root user.

rvmsudo ./bin/passenger-install-nginx-module
