rails生成rspec:install returns'；在任何源'；

目前，我正在阅读Michael Hartl的Ruby on Rails教程第3章（），运行以下命令后，我收到一个错误：

rails generate rspec:install

这就是我得到的错误：

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“bundle install”，我将得到以下输出：

Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.

如果我键入“bundle show addressable”，我可以看到“addressable-2.2.8”的路径

这就是我的gemfile的外观：

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：我感觉这可能与我正在使用rbenv有关。我有一种感觉，rails项目在这个特定的依赖项上找错了地方。有没有办法强制rails应用程序在应用程序本身中存储依赖项/gem并始终将它们加载到其中？

尝试：

bundle exec rails generate rspec:install

我遇到了同样的问题。以下是我修复它所遵循的步骤

确保

source'https://rubygems.org“

是文件中的第一行

rm-rf.bundle

bundle安装
