Ruby on Rails：错误“require”：无法加载此类文件——bundler/setup (LoadError)

Question

I'm trying to set up redmine on an managed server. Redmine installation works, I can start the rails server and visit the redmine page localy with lynx. Integration in the Apache is done via FCGI and when I enter the redmine start page in my browser I get an Server error 500. In the server logs I see this:

I searched for the errormessage other answers recommended an bundle install - output is

...
Bundle complete! 27 Gemfile dependencies, 58 gems now installed.
Gems in the groups development, test and rmagick were not installed.
Bundled gems are installed into `/usr/home/admin/.gem`

EDIT additional info: I continued searching for answers, maybe the GEM_PATH is the problem and ruby can't find the bundle/setup. My fcgi script looks like this:

#!/bin/dash                                                                                                                                       
export GEM_HOME="$HOME/.gem/ruby/2.3.0/"
export GEM_PATH="$GEM_HOME:/var/lib/ruby/gems/1.8"
exec /usr/bin/ruby /usr/www/users/admin/redmine/startup.rb

How can I find the location of the 'bundle/setup' on my system?

Any idea what I can do?

Thanks a lot Klaus

Looks that you have ambiguity with your ruby & gem paths. They are installed in /usr/home/admin/.gem and fcgi is trying to find them in /usr/lib/ruby/2.3.0/rubygems/ that's because Apache doesn't know where to look.

You should try passing env config variables via .htaccess file if your shared hosting system allows it or via apache config

SetEnv GEM_HOME /usr/home/admin/.gem

However, Redmine is preferably used via some application server (puma, thin, webrick...) , and reverse-proxied or run via Passenger as Apache module, and preferably it uses Ruby installed via rvm or rbenv...

Thus, depending upon version, it might also require you to add

gem "fcgi" in Gemfile and run bundle install again, and also to add these lines in dispatch.fcgi

require 'rubygems'
require 'fcgi'
