Question

我使用http://jaysonrowe.blogspot.com/2012/04/installing-ruby-and-rails-on-fedora.html在rails环境中设置ruby。我安装了mysql 5.5。现在，当我从bitbucket克隆一个项目并运行bundle install时，我收到以下错误：

[xyz@xyz ruby_repo]$ bundle install
Fetching gem metadata from http://rubygems.org/......
Fetching gem metadata from http://rubygems.org/..
Could not find capistrano-2.13.3 in any of the sources

当我在ruby_repo目录中执行rails -v时，出现以下错误：

[xyz@xyz ruby_repo]$  rails -v
Could not find abstract-1.0.0 in any of the sources
Run `bundle install` to install missing gems.

以下是我的Gemfile：

source 'http://rubygems.org'

gem 'rails', '3.0.10'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
gem 'rmagick'
gem "will_paginate", "~> 3.0.pre2"
gem 'mysql2','0.2.7'
gem "nokogiri"
gem 'activemerchant', :require => 'active_merchant'
gem "webrobots", "~> 0.0.10"
gem 'mixpanel'
gem 'thinking-sphinx', '2.0.10'
gem 'whenever', :require => false
gem 'json'
gem 'vimeo'
gem "koala"
gem 'typhoeus'
gem 'delayed_job_active_record'
gem "delayed_job"
gem 'mini_fb'
gem 'daemons'
gem 'annotate'
gem 'capistrano'
gem 'rvm-capistrano'
gem 'grosser-ssl_requirement', :require => 'ssl_requirement'
gem 'acts-as-taggable-on'
gem 'capistrano'
gem 'rvm-capistrano'
# Use unicorn as the web server
# gem 'unicorn'

# Deploy with Capistrano
#gem 'capistrano'
#gem 'capistrano-ext'
#To use debugger (ruby-debug for Ruby 1.8.7+, ruby-debug19 for Ruby 1.9.2+)
# gem 'ruby-debug'


# Bundle the extra gems:
# gem 'bj'
# gem 'nokogiri'
# gem 'sqlite3-ruby', :require => 'sqlite3'
# gem 'aws-s3', :require => 'aws/s3'

# Bundle gems for the local environment. Make sure to
# put test-only gems in this group so their generators
# and rake tasks are available in development mode:
# group :development, :test do
#   gem 'webrat'
# end

当我执行gem list时，我得到以下输出

然而，当我创建一个全新的项目时，我不会遇到任何此类问题。有人可以告诉我可能是什么问题吗？

Answer 1

此版本已从rubygems.org中删除。通过以这种方式运行bundle update来更新capistrano：

bundle update capistrano

这样您只能将capistrano更新为当前版本。如果删除Gemfile.lock并运行bundle，那么所有gem版本都会更新，通常不是你想要的。

Answer 2

删除Gemfile.lock或文件本身的内容。

Answer 3

我只是想出了问题。麻烦制造者是rvm。我为我的app创建了一个gemset，并在这个gemset中运行bundle。但是，出于某种原因，当我运行rails c或捆绑exec rails c时，它仍会在全局gemset中查找它所需的gem。

因此，在我访问全球gemset并安装所有宝石之后，它就可以了。不确定它是单独的rvm gemset故障，还是bundle + rvm gemset的组合。

在任何来源中都找不到capistrano-2.13.3
