我一直在使用selenium IDE.现在我们决定使用Selenium webdriver和Ruby.我对如何设置Mac,Mac Pro Yosemite 10.10.5感到困惑.

在我的终端中,我运行了以下命令:

$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
$ brew doctor
Your system is ready to brew.
$ brew install ruby

$ ruby -v
ruby 2.2.3p173 (2015-08-18 revision 51636) [x86_64-darwin14]

$ sudo gem install selenium-webdriver
   Done installing documentation for websocket, ffi, childprocess, rubyzip, multi_json, selenium-webdriver after 25 seconds
6 gems installed

我将从IDE记录的脚本导出到Ruby脚本中:export as ruby/rspec/webdriver …

我正在关注教程http://learnrubythehardway.org/book/ex50.html，它提供了：

创建尽可能最基本的 Sinatra 应用程序。将以下代码放入bin/app.rb：

require 'sinatra'

set :port, 8080
set :static, true
set :public_folder, "static"
set :views, "views"

get '/' do
    return 'Hello world'
end

我安装了 gem 和 Sinatra 没有任何问题。我还将教程中的内容复制app.rb到本地bin/app.rb文件中。

我运行它：ruby bin/app.rb

终端输出：

/home/t/.rbenv/versions/2.2.0/lib/ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in 'require': cannot load such file -- sinatra (LoadError)
    from /home/t/.rbenv/versions/2.2.0/lib/ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in 'require'
    from bin/app.rb:1:in `<main>

当我运行时rake test它通过了测试。有什么问题？
