Package package does not work when running inside rake task

Question

My environment

Vanilla Ubuntu 12.10, no rvm or renv.

> gem --version 1.8.23 > ruby --version ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-linux] > bundle --version Bundler version 1.2.1 

My problem

I have a rake task to pack my gems and upload them to my development and production servers. The problem is that the rake task does not work when the gemfile contains git or road graphs. Bundler already supports the packaging of these types of gemstones, and it works great on my terminal, but it fails when dealing with the rake job, and I can't figure out why.

My task is rake

 > cat lib/tasks/upload.rake namespace :deploy do desc "Package all gems and upload to remote server" task :upload => [:environment] do |t, args| if ! system("bundle package --all") raise "TOTAL FAIL" end # Magic method to upload vendor/cache to remote server end end 

My attempts

Running the package package in the terminal works:

 > bundle package --all .... Using bson (1.7.0) Using bson_ext (1.7.0) Using cancan (1.6.8) from git://github.com/ryanb/cancan.git (at /home/ryujin/Projects/rails/Encluster4/vendor/cache/cancan-4dcd54459482) Using carrierwave (0.7.0) Using coffee-script-source (1.4.0) .... Updating files in vendor/cache Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed. Updating files in vendor/cache 

Running the package package with irb:

 > irb irb> system("bundle package --all") ... Using ansi (1.4.3) Using bson (1.7.0) Using bson_ext (1.7.0) Using cancan (1.6.8) from git://github.com/ryanb/cancan.git (at /home/ryujin/Projects/rails/Encluster4/vendor/cache/cancan-4dcd54459482) Using carrierwave (0.7.0) Using coffee-script-source (1.4.0) ... Updating files in vendor/cache Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed. Updating files in vendor/cache => true 

But the package package does not work when performing my simple task:

 > bundle exec rake deploy:upload Updating files in vendor/cache Could not find cancan-1.6.8.gem for installation rake aborted! TOTAL FAIL Tasks: TOP => deploy:upload (See full trace by running task with --trace) 

I find no reason why this may fail. I constantly work in the same environment. I have already verified that the exec bundle file is the same (/ usr / local / bin / bundle) in all three cases. I have no traces of either rvm or renv or anything like that. Also tried to run the task without execle exec and the same problem.

Thanks in advance for any advice on why this is happening.

Answer 1

I had the same problems. I checked the environment variables and found out that the binding agent modifies RUBYOPT:

 $ bundle exec env > benv.txt $ env > env.txt $ diff -u env.txt benv.txt --- env.txt 2012-12-05 17:13:10.000000000 +0400 +++ benv.txt 2012-12-05 17:13:07.000000000 +0400 @@ -72,4 +72,8 @@ CDPATH=. install_flag=1 rvm_hook= -_=/usr/bin/env +_=/Users/denis/.rvm/gems/ ruby-1.9.3-p327@global /bin/bundle +_ORIGINAL_GEM_PATH=/Users/denis/.rvm/gems/ruby-1.9.3-p327:/Users/denis/.rvm/gems/ ruby-1.9.3-p327@global +BUNDLE_BIN_PATH=/Users/denis/.rvm/gems/ ruby-1.9.3-p327@global /gems/bundler-1.2.3/bin/bundle +BUNDLE_GEMFILE=/Users/denis/src/my-project/Gemfile +RUBYOPT=-I/Users/denis/.rvm/gems/ ruby-1.9.3-p327@global /gems/bundler-1.2.3/lib -rbundler/setup 

So, to solve this problem, I do this:

 system %Q(/usr/bin/env RUBYOPT= bundle package) 

Hope this helps!

You may also prefer to use

 Bundler.with_clean_env do sh "bundle update --source .." end 

and indeed, this is the RUBYOPT problem that Denis talked about
