使用NGINX的Passsenger无法加载此类文件-捆绑程序/安装程序（LoadError）

Question

I have a rails app deployed on debian 7 server, it was working till now. I deploy code using mina, since my reposiory link has changed, i deleted project and updated repository details and pushed new code to server and restarted nginx.
SInce then i am getting this error:

Could not spawn process for application /opt/www/app.co/app: 
An error occured while starting up the preloader.
Error ID: 6d901b8e

I am unable to resolve this load error.

Tried below as mentioned by others, but it didn't help

gem bundler install && bundle install

My app requires ruby-2.1.5

rvm list
rvm rubies

=* ruby-2.1.5 [ x86_64 ]

which ruby

/usr/bin/ruby

In /opt/nginx/conf/nginx.conf, i have :

passenger_root /var/lib/gems/1.9.1/gems/passenger-4.0.53;
passenger_ruby /home/deployer/.rvm/gems/ruby-2.1.5/wrappers/ruby;

Tried using default ruby in passenger_ruby as ruby -v gives 1.9.1

ruby -v
ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-linux]

But couldn't resolve.

Kindly help me in resolving this as early as possible.

It sounds like your app is being run under a user that you did not expect it to. Could you read Sandboxing apps with Unix user accounts (user switching) to learn how Passenger runs your app under different users, and see whether you can troubleshoot your issue with this knowledge?
