使用nginx的乘客：无法加载此类文件 - bundler / setup（LoadError）

Question

There is only one version of Ruby installed, and I have run gem install bundler && bundle install .

nginx conf

passenger_root /root/.gem/ruby/2.1.0/gems/passenger-4.0.52;
passenger_ruby /usr/bin/ruby;
server {
    listen 80;
    server_name example.com;
    root /srv/http/myrailsapp/public;
    passenger_enabled on;
    rails_env development;
}

Error Log

Answer 1

I have been solving similar issue.

My problem was in configuration of passenger_ruby /usr/bin/ruby; Which points to the incorrect version. My solution was to set the path to output of command which ruby

On the server I use rvm. But there are aslo other instalations of ruby.

At first try to test the environment. Go to the application directory and run passenger start . This will show you you, if the server is ready to run the app. Fix the errors...

If the message still says that

cannot load such file -- bundler/setup (LoadError)

run gem install bundler and re-check.

Then set up the path in NGINX to path from which ruby command and restart the appllication.

You need to change your passenger_root value. Like here in doc

For example my nginx config:

...
  passenger_root /usr/lib/ruby/vendor_ruby/phusion_passenger/locations.ini;
  passenger_ruby /usr/bin/ruby;
...
