Rails 生成 rspec:install 返回'Could not find addressable-2.2.8 in any of the sources'



目前我正在学习Michael Hartl的Ruby on Rails教程,第3章(http://ruby.railstutorial.org/chapters/static-pages#top(,运行以下命令后收到错误:

rails generate rspec:install

这是我得到的错误:

Could not find addressable-2.2.8 in any of the sources
Run 'bundle install' to install missing gems.

如果我重新运行"捆绑安装",这就是我得到的输出:

如果我键入"捆绑显示可寻址">

,我可以看到"可寻址-2.2.8"的路径。

这是我的宝石文件的样子:

source 'https://rubygems.org'
gem 'rails', '3.2.3'
group :development, :test do
gem 'sqlite3', '1.3.5'
gem 'rspec-rails', '2.10.0'
gem 'addressable', '2.2.8'
end
# Gems used only for assets and not required
# in production environments by default.
group :assets do
    gem 'sass-rails', '3.2.4'
gem 'coffee-rails', '3.2.2'
gem 'uglifier', '1.2.3'
end
gem 'jquery-rails', '2.0.0'
group :test do
gem 'capybara', '1.1.2'
end
group :production do
gem 'pg', '0.12.2'
end

知道我正在使用 rbenv、rails 3.2.3 和 ruby 1.9.3p194 可能会有所帮助。

编辑:我有一种感觉,这可能与我正在使用rbenv的事实有关。我有一种感觉,rails 项目在这个特定依赖项的位置上找错了地方。有没有办法强制 rails 应用程序将依赖项/gem 存储在应用程序本身中并始终将它们加载在那里?

我遇到了同样的问题。 以下是我修复它的步骤。

  1. 确保source 'https://rubygems.org'是宝石文件中的第一行。
  2. rm -rf .bundle
  3. bundle install

尝试: bundle exec rails generate rspec:install
