Deployment Bundler:：GemNotFound:在任何源中都找不到net-ssh-2.7.0

我已将capistrano添加到我的文件中。运行bundle命令后，出现以下错误：

Bundler:：GemNotFound:在任何源代码中都找不到net-ssh-2.7.0

这是我的档案：

source 'https://rubygems.org'

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.0.1'

# Use mysql as the database for Active Record
gem 'mysql2'

# Use SCSS for stylesheets
gem 'sass-rails', '~> 4.0.0'

# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '>= 1.3.0'

# Use CoffeeScript for .js.coffee assets and views
gem 'coffee-rails', '~> 4.0.0'

# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer', platforms: :ruby

# Use jquery as the JavaScript library
gem 'jquery-rails'

# Turbolinks makes following links in your web application faster. Read more: https://github.com/rails/turbolinks
gem 'turbolinks'

# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder
gem 'jbuilder', '~> 1.2'

group :doc do
  # bundle exec rake doc:rails generates the API under doc/api.
  gem 'sdoc', require: false
end


gem 'simple_form'
gem 'jquery-rails'
gem 'less-rails'
gem 'therubyracer'

gem "liquid"

gem "devise"
gem "devise-basecamper"
gem "cancan"
gem 'userstamp', git: 'git://github.com/andrezimpel/userstamp.git'



# Use ActiveModel has_secure_password
# gem 'bcrypt-ruby', '~> 3.1.2'

# Use unicorn as the app server
# gem 'unicorn'

# Use Capistrano for deployment
group :development do
  gem 'capistrano'
end

# Use debugger
# gem 'debugger', group: [:development, :test]

当我删除

gem'capistrano'

时，一切正常

我不确定问题出在哪里，我希望有人能帮助我。

运行

rvm env.>。powenv为我工作

看来战俘给我惹了点麻烦
