“捆绑安装”错误
我正在使用 Michael Hartl 的“Ruby on Rails 示例教程”（截屏视频），在第三节课（示例应用程序）中尝试“捆绑安装”时遇到了一些错误。
我按照教程中所示更改了 Gemfile，如网站（更新后的）所示，甚至尝试了本教程的最终 Gemfile。每次我收到不同的错误，表明无法安装某些内容，并且捆绑包安装无法继续。
首先它说的是“nokogiri”，然后是“json”，现在是“bcrypt”。当我制作第一个应用程序和演示应用程序时，这种情况没有发生。也许是因为现在我尝试添加了 rspec？我不想在不将其添加到 Gemfile 的情况下继续本教程，因为它听起来很重要。
我正在运行 osx lion 10.7.2，rails 版本 3.0.1。
将 Gemfile 代码从评论复制到原始帖子中：
source 'rubygems.org';
gem 'rails', '3.0.1'
gem 'sqlite3-ruby', '1.2.5', :require => 'sqlite3'
group :development do
gem 'rspec-rails', '2.0.0.beta.18'
end
group :test do
gem 'rspec', '2.0.0.beta.18'
end
更新： 我从某人那里听说 rspec 是用于测试的 gem，因此您无法在没有默认测试的情况下创建 Rails 项目，然后更改 gemfile。那么，为什么在教程中他创建了一个“rails new example_app -T”，但事后更改了 Gemfile，使其使用 rspec？他说，他们互相取代。 rspec 取代了原始测试，因此您需要创建一个没有原始测试的项目。对此有何想法？
I'm using the "ruby on rails by example tutorial" (screencasts) by Michael Hartl and I'm getting some errors during the third lesson (sample app) while trying to do "bundle install".
I changed the Gemfile as shown in the tutorial, as shown in the website(the updated one), and even tried the final Gemfile for this tutorial. Every time I get a different error that something couldn't been install, and the bundle installation could not continue.
At first it said it about 'nokogiri', then 'json', and now 'bcrypt'. This did not happen when I did the first app and the demo app. maybe because now I tried added the rspec? I don't want to continue the tutorial without adding it to the Gemfile, because it sounds important.
I'm running osx lion 10.7.2, rails version 3.0.1.
Copying Gemfile code from comment into original post:
source 'rubygems.org';
gem 'rails', '3.0.1'
gem 'sqlite3-ruby', '1.2.5', :require => 'sqlite3'
group :development do
gem 'rspec-rails', '2.0.0.beta.18'
end
group :test do
gem 'rspec', '2.0.0.beta.18'
end
update: I heard from someone that rspec is a gem used on tests, therefore you can't make a rails project without the default test and then change the gemfile. So why in the tutorial he make a "rails new sample_app -T" but afterwords changes the Gemfile so it uses rspec? he says, that they replace each other. that rspec replace the original test, and therefore you need to make a project without the original test. any thoughts on this?

我为这个错误困扰了几个小时，然后检查了 rspec github 页面。根据他们的指示，您需要包含 github 的路径。所以我由 Gemfile 制作的看起来如下，现在可以工作了：
我正在使用 Ruby 1.9.3、Rails 3.2.1、RVM 1.10.2、Bundler 1.0.21
I screwed around with this error for a few hours, then checked the rspec github page. Per their instructions, you need to include the path to github. So I made by Gemfile look like following and it now works:
