Question

目前我正在阅读Michael Hartl撰写的Ruby on Rails教程，第3章（http://ruby.railstutorial.org/chapters/static-pages#top），我在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'bundle install'，这就是我输出的内容：

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

如果输入'bundle show addressable'，我可以看到'addressable-2.2.8'的路径。

这是我的gemfile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

知道我使用rbenv，rails 3.2.3和ruby 1.9.3p194可能会有所帮助。

编辑：我觉得这可能与我使用rbenv的事实有关。我有一种感觉，rails项目正在寻找这个特定依赖项的错误位置。有没有办法强制rails应用程序在应用程序本身存储依赖项/ gems并始终将它们加载到那里？

Answer 1

我遇到了同样的问题。以下是我修复它的步骤。

确保source 'https://rubygems.org'是Gemfile中的第一行。
rm -rf .bundle
bundle install

Answer 2

尝试：bundle exec rails generate rspec:install

rails生成rspec：install返回'找不到任何来源中的addressable-2.2.8'
