bundle install doesn't work from capistrano

Question

I want to deploy my simple rails 4.0 application via capistrano 3.0.

I use bundler 1.3.5 so I add capistrano-bundler gem to integ

Answer 1

Just ran into the same issue. What worked for me was this:

1) Installing the capistrano-rvm gem and adding

require 'capistrano/rvm'

to the Capfile.

2) Adding my deployment user to the rvm group on the server:

# usermod deploy -a -G rvm

3) Creating two directories in my deployment user's home folder: .rvm and .rvm/bin

4) Adding this line to my deploy.rb file:

set :default_env, { rvm_bin_path: '~/.rvm/bin' }

Phew! That took a few hours.

Answer 2

in your config/deploy/production.rb file put

set :rvm_ruby_version, '2.0.0-p247'  

see https://github.com/capistrano/rvm

Answer 3

I had:

set :bundle_flags, '--system --quiet'

Changed to:

set :bundle_flags, '--deployment --quiet'

This resolved a problem.

Answer 4

To debug it try to remove the --quiet flag:

set :bundle_flags, '--deployment'

Are you using rbenv, rvm or something similar? It might be possible that when bundle is running the Ruby version is not set yet. By removing the --quite flag you might get some debugging information.

Answer 5

The error sounds like it can't find bundle in your PATH. It's possible that when you SSH in manually, it's running something in your ~/.profile or ~/.bash_profile that adds it to your path.

Find the path to bundle by logging in and running which bundle. Then, try to find how that path is added to your PATH environment variable. If there's something in your ~/.bash_profile, try moving it to~/.bashrc` instead.

You can also try Command Mapping to specify an exact path.

Answer 6

This works in capistrano 3:

  task :bundle_list do
    on roles(:app) do
      within release_path do
        with rails_env: fetch(:rails_env) do
          execute :bundle, "list"
        end
      end
    end
  end

Use this for rake task :

execute :rake, 'some_rake_task'
