I want to exec sinatra app from supervisord. sinatra gem is installed in /home/lastcat(<-my username)/.rbenv/shims/gem.
I wrote following sinatra.conf.
[program:sinatra]
user=lastcat
environment=PATH="/home/lastcat/.rbenv/shims:/home/lastcat/.rbenv/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games"/home/lastcat/Documents/tmp/app.rb
command=ruby /home/lastcat/Documents/tmp/app.rb
redirect_stderr=true
stdout_logfile=/var/log/supervisor/sinatra.log
but, when I exec sudo supervisorctl start sinatra, this error happen.
from /home/lastcat/Documents/tmp/app.rb:1:in `<main>'
/usr/lib/ruby/2.1.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- sinatra (LoadError)
from /usr/lib/ruby/2.1.0/rubygems/core_ext/kernel_require.rb:55:in `require'
I suspected supervisor cannot see gem path for some reason. I change command to which ruby and which gem, and confirm their result.But they are /home/lastcat/.rbenv/shims/rubyand/home/lastcat/.rbenv/shims/gem.
next, I change command to gem list.Then, output is,
bigdecimal (1.2.4)
bundler (1.10.6)
io-console (0.4.2)
json (1.8.1)
minitest (4.7.5)
psych (2.0.5)
rake (10.1.0)
rdoc (4.1.0)
test-unit (2.1.2.0)
It is unexpected result.Result of gem list by user:lastcat,
bigdecimal (1.2.0)
bundler (1.10.6)
~
sinatra (1.4.6)
~
ofcourse, result of which gemandwhich ruby by normaly execed by lastcat, equal to previous them.
In other words, supervisor see another path when which gem and when gem list I don't understand this phenomenon.
post sctripts: result of sudo gem list is equal to gem list by supervisor.It exec command in root enviroment……?
You need to set GEM_PATH in environment:
environment=GEM_PATH="YOUR_GEM_PATH"
And print ENV in IRB to find your GEM_PATH.

I am using ruby version 2.3.3p222
Here is my Gemfile:
# Gemfile
source 'https://rubygems.org'
gem 'pry'
I run bundle and here is the resulting Gemfile.lock
Gemfile.lock
GEM
remote: https://rubygems.org/
specs:
coderay (1.1.2)
method_source (0.9.2)
pry (0.12.2)
coderay (~> 1.1.0)
method_source (~> 0.9.0)
PLATFORMS
ruby
DEPENDENCIES
pry
BUNDLED WITH
1.15.1
I then simply run a ruby script via ruby my_report.rb (this script is located in the same directory as Gemfile and Gemfile.lock). my_report.rb only has this in the file:
require 'pry'
Here is the error:
WARN: Clearing out unresolved specs.
Please report a bug if this causes problems.
/Users/<user>/.rvm/gems/ruby-2.3.3/gems/pry-rescue-1.4.5/lib/pry-rescue.rb:15: warning: method BaseHelpers#windows? is deprecated. Use Pry:Helpers::Platform.windows? instead

Question: What am I missing? How can I properly require in pry into my ruby script so that I can set breakpoints?
What eventually worked for me is I just uninstalled all of the pry versions I had installed via gem uninstall. Then: in my gemfile I specified a previous version of 0.11.3:
# Gemfile
source 'https://rubygems.org'
gem 'pry', '0.11.3'
I did bundle install and then ran my ruby script, and that worked for me.
I'm writing Ruby scripts on Linux Mint 14 under RVM. In both Ruby 2.0 and 1.9.3, when I try to run what I'm working on, I get the error:
/home/tom/.rvm/rubies/ruby-1.9.3-p392/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- Nokogiri (LoadError)

Nokogiri is installed; gem list gives:
*** LOCAL GEMS ***

The file in question starts with require 'Nokogiri'. Running the file with sudo doesn't make a difference, nor does using the terminal vs. running it in Geany.
Not Nokogiri rather, you should write as below
require 'nokogiri'
See SYNOPSIS:
I'm currently trying to install Webistrano on a freshly installed debian squeeze 64bits, but I'm facing some issues that I can't manage to solve.
Note: The machine is created under Xen environment, I don't think this affect the procedure however it seemed important to mention it.
Procedure:
Informations:
Ruby version: ruby 1.8.7 (2010-08-16 patchlevel 302) [x86_64-linux]
Rails version: `Rails 2.3.11
Path modifier with: /usr/lib/ruby/1.8:/var/lib/gems/1.8/bin
Rails env: development
Databases have been created
Databases setups for webistrano are, I believe correct (user/pass/path_to_sock_file)
So, here is what I did:
I first installed the 'basics' packages for such installation:
# apt-get install build-essential ruby rubygems libmysql-ruby libmysqlclient-dev libdbd-mysql-ruby mysql-server unzip rake
Then I have been downloading and extracting the project into /usr/src. After copying and configuring the files for email/databses setups (as suggested by https://github.com/peritor/webistrano), I continued by installing all the gems needed for the project:
bundle install
at this point, the command is stuck and isn't doing anything for an hour.
I know it can happen if the Gemfile is complicate, but it doesn't seem to be the case for me. (see the Gemfile following)
# cat Gemfile
source "http://rubygems.org"
gem 'bundler', "~>1.0.10"
gem "rails", "2.3.11"
gem "mysql"
gem "erubis"
gem "rake"
gem "syntax", "1.0.0"
gem "capistrano", "2.6.0"
gem "open4", "0.9.3"
gem "exception_notification", "2.3.3.0"
group :test do
gem "mocha", "0.9.8"
end
So deciding to go ahead I installed the gems by hands, which once finished gives:
# gem list *gems of Gemfile*
bundler (1.0.10)
rails (2.3.11)
mysql (2.8.1)
erubis (2.7.0)
rake (0.9.2.2)
syntax (1.0.0)
capistrano (2.6.0)
open4 (0.9.3)
exception_notification (2.3.3.0)
mocha (0.9.8)
So I believe everything should be working without having to run: bundle install
This is why I finally tried to create the database's structure with rake:
# rake db:migrate --trace
(in /usr/src/peritor-webistrano-a98ba6b)
rake aborted!
Bundler couldn't find some gems.Did you run `bundle install`?

According to rake error message, apparently some gems aren't properly installed, which seems weird to be, but I guess he can't find it.
So I double check with bundle tool:
# bundle check
Your Gemfile's dependencies could not be satisfied
Install missing gems with `bundle install`
# bundle show
Could not find gem 'mocha (= 0.9.8, runtime)' in any of the gem sources listed in your Gemfile.
And I'm stuck here, I just don't know how to continue.
I google around about mocha or gemfile issue, but haven't found much relevant.
I hope everything is clear and easy to understand as this is my first post.
Thanks for any reply/hints, also if I manage to evolve I'll try keeping you up to date!

Your bundle is updated! Use `bundle show [gemname]` to see where a bundled gem is installed.
I've got a simple script that uses sinatra. Should be simple, right? Apparently not.
The code:
require 'rubygems'
require 'sinatra'
That's all there is. And it fails, saying:
tekknolagi#eos ~/indexer $ ruby torrent.rb
/usr/lib/ruby/vendor_ruby/1.8/rubygems/custom_require.rb:36:in `gem_original_require': no such file to load -- torrent-ruby (LoadError)
from /usr/lib/ruby/vendor_ruby/1.8/rubygems/custom_require.rb:36:in `require'
from torrent.rb:2
I gem installed it several times over, just to make sure I wasn't going crazy. What could be going wrong and how can I fix it?
Oh, and here's my list of installed gems:
tekknolagi#eos ~/indexer $ gem list
*** LOCAL GEMS ***
rack (1.4.1)
rack-protection (1.2.0)
rake (0.9.2.2)
sinatra (1.3.2)
sqlite3 (1.3.6)
tilt (1.3.3)
torrent-ruby (0.1.4)
I believe you have done everything right. Many times this custom require error appears when the gem is not installed in the proper path. Try not using the explicit require. Use this instead..:
require_relative 'sinatra'
Using jruby-1.6.7 via rvm and gem version 1.8.24 I created a new project containing a Gemfile:
source 'http://rubygems.org'
gem 'google-api-client'
and a main.rb:
require 'google/api_client'
After
gem install bundler
bundle install
gem list
I get

autoparse (0.3.1)
bouncy-castle-java (1.5.0146.1)
bundler (1.1.4)
extlib (0.9.15)

rubygems-update (1.8.24, 1.7.2)
rvm (1.11.3.3)
signet (0.3.4)
spoon (0.0.1)
But when I run ruby main.rb, it results in an error:
LoadError: no such file to load -- google/api_client
require at org/jruby/RubyKernel.java:1033
(root) at main.rb:1
On MRI everything seems to be working fine. The problem does not seem bound to any specific gem.
Can someone help me with this?
Unless you have JRUBY_OPTS=--1.9 in your environment, or you pass the --1.9 flag on the command line, JRuby will default to 1.8 mode, which means that you explicitly have to require 'rubygems' in main.rb before you load your gems.
