Ruby on Rails：使用capistrano部署时未安装捆绑器

Question

I'm trying to deploy to a ubuntu server using capistrano and get the following error:

Executing "cd /home/useracc/www/releases/20130420101911 && bundle install --gemfile /home/useracc/www/releases/20130420101911/Gemfile --path /home/useracc/www/shared/bundle --deployment --quiet --without development test"
    servers: ["dev.website.com"]
    [dev.self-sale.com] executing command
 ** [out :: dev.website.com] ERROR: Gem bundler is not installed, run `gem install bundler` first.
 ** [out :: dev.website.com] 
    command finished in 510ms
*** [deploy:update_code] rolling back
  * executing "rm -rf /home/useracc/www/releases/20130420101911; true"
    servers: ["dev.website.com"]
    [dev.self-sale.com] executing command
    command finished in 613ms
failed: "sh -c 'cd /home/selfsale/www/releases/20130420101911 && bundle install --gemfile /home/useracc/www/releases/20130420101911/Gemfile --path /home/useracc/www/shared/bundle --deployment --quiet --without development test'" on dev.website.com

I've done some searching and found that some people have resolved this issue by putting require "bundler/capistrano" in their deploy.rb.

I've tried that but it's not made any difference.

I have also tried installing bundler on the server but get:

$ gem install bundler
Fetching: bundler-1.3.5.gem (100%)
ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions into the /usr/local/rvm/gems/ruby-1.8.7-p371 directory.

I don't remember setting RVM up though, so this is a little confusing to me.

Does any one have any suggestions?

This is an old app btw, here is my gem list:

% bundle exec gem list

* LOCAL GEMS *

actionmailer (2.3.14) actionpack (2.3.14) activerecord (2.3.14) activeresource (2.3.14) activesupport (2.3.14) brightbox (2.3.9) bundler (1.3.5) capistrano (2.14.2) highline (1.6.16) hoe (3.5.2) hpricot (0.8.2) htmldoc (0.2.3) json (1.7.7) macaddr (1.6.1) mysql (2.9.1) net-scp (1.1.0) net-sftp (2.1.1) net-ssh (2.6.7) net-ssh-gateway (1.2.0) paginator (1.1.1) rack (1.1.6) rails (2.3.14) rake (10.0.4) rdoc (4.0.1) RedCloth (4.2.9) rmagick (2.13.1) systemu (2.5.2) uuid (2.0.2) will_paginate (2.3.16) wkhtmltopdf-binary (0.9.9.1)

我认为问题是：您已将bundler安装到特定的gemset，这就是为什么只有在应用程序目录中才可用的原因，因此请尝试将bundler安装到全局gemset。

rvm gemset use global && gem install bundler
