Unicorn error with ruby_dep gem - Rails app

I have the following error, saying that couldn’t find the gem ruby_dep-1.4.0 but as you see when i listed the gem it’s already installed. How can I solve this?

root@RCSO-server:/home/rails/rcso# gem list ruby_dep

*** LOCAL GEMS ***

ruby_dep (1.4.0)
root@RCSO-server:/home/rails/rcso#

/var/log/unicorn

The problem was that I had setup the path on the unicorn file wrong, I used rvm to set my ruby env to 2.2.5, and unicorn had the PATH, GEMPATH and GEMHOME pointing to ruby 2.2.1, I just changed the ruby version on /etc/default/unicorn file:

Preview

#PATH=/usr/local/rvm/rubies/ruby-2.2.1/bin:/usr/local/sbin:/usr/bin:/bin:/sbin:/usr/local/rvm/bin:/usr/local/rvm/gems/ruby-2.2.1@global/bin:/usr/local/rvm/gems/ruby-2.2.1/bin/
#export GEM_HOME=/usr/local/rvm/gems/ruby-2.2.1
#export GEM_PATH=/usr/local/rvm/gems/ruby-2.2.1:/usr/local/rvm/gems/ruby-2.2.1@global
#DAEMON=/usr/local/rvm/gems/ruby-2.2.1/bin/unicorn

After change

PATH=/usr/local/rvm/rubies/ruby-2.2.5/bin:/usr/local/sbin:/usr/bin:/bin:/sbin:/usr/local/rvm/bin:/usr/local/rvm/gems/ruby-2.2.5@global/bin:/usr/local/rvm/gems/ruby-2.2.5/bin/
export GEM_HOME=/usr/local/rvm/gems/ruby-2.2.5
export GEM_PATH=/usr/local/rvm/gems/ruby-2.2.5:/usr/local/rvm/gems/ruby-2.2.5@global
DAEMON=/usr/local/rvm/gems/ruby-2.2.5/bin/unicorn

I’m no Bundler expert, but a guess would be that the gem was installed directly via “gem install” (and thus the Gemfile makes no reference to it) and Unicorn is being run via “bundle exec”.

Just a guess :)
