Ruby on Rails, nginx, passenger on the production server (it is impossible to load such a file - rubygems / path_support)

Question

I have installed:

• Centos 6
• Ruby 1.9.3-rc1
• Passenger nginx gem and passenger module (compiled against native source 1.1.6)
• Mounted Rails 3.1.0
• Made / srv
• Was there a new reils test
• install package
• made vhost for the passenger inside nginx based on the / srv / test / public example
• nginx stop service && & nginx start service
• ruby app loads okay index.html but then ...

After clicking the link "check application environment", which is inside the standard /public/index.html, I get this error

cannot load such file - rubygems / path_support

Question: Anyone know how I can resolve the cannot load such file -- rubygems/path_support error? Full error post below

Answer 1

I had a similar problem, although I had rvm and ruby ​​installed for only one user. For me, the solution was to verify that the application files belong to the same user for whom the ruby ​​was installed.

In my case, I also met this problem:
(My environment: Centos 5.8, rbenv 1.9.3p327, passenger 3.0.19, nginx (compiled and installed by the passenger). I googled around but did not find a direct answer (keyword: rbenv, passenger, cannot load such file -- rubygems/path_support ), so I am writing my solution here.

I checked and installed root for the nginx user, but it does not work. and changed all privileges of the gem folder to 777. It does not work.

Finally, I got a solution: add these 2 lines of code to your Nginx configuration file:

 passenger_default_user root; passenger_default_group root; 

now your nginx configuration file looks like this:

 # /opt/nginx/config/nginx.conf user root; # seems this line of code doesn't take effect. http { passenger_root /root/.rbenv/versions/1.9.3-p327/lib/ruby/gems/1.9.1/gems/passenger-3.0.19; passenger_ruby /root/.rbenv/versions/1.9.3-p327/bin/ruby; # these lines are the key!!! passenger_default_user root; passenger_default_group root; server { listen 80; root <your_rails_project_public_folder>; passenger_enabled on; } }

I had the same problem. Timo is right.

your application should install the directory / home / rvm _user /.

Example:

 # vi /etc/conf/httpd.conf LoadModule passenger_module /home/rvm_user/.rvm/gems/ruby-1.9.3-rc1/gems/passenger-3.0.9/ext/apache2/mod_passenger.so PassengerRoot /home/rvm_user/.rvm/gems/ruby-1.9.3-rc1/gems/passenger-3.0.9 PassengerRuby /home/rvm_user/.rvm/wrappers/ruby-1.9.3-rc1/ruby <VirtualHost *:80> ServerName www.yourhost.com DocumentRoot /home/rvm_user/your_application/public <Directory /home/rvm_user/your_application/public> AllowOverride all Options -MultiViews </Directory> </VirtualHost> # chmod 755 /home/rvm_user/ # /etc/rc.d/init.d/httpd restart
