問題與軌軌-V

Question

我的朋友剛剛告訴我這個新的應用程序，我從Heroku的

把它

我只是試圖做軌道-v和我

denniss$ rails -v 
/Users/denniss/.rvm/gems/ruby-1.9.2-rc2/gems/bundler-1.0.0.rc.5/lib/bundler/resolver.rb:132:in `block in resolve': Could not find gem 'selenium-webdriver', required by 'capybara', in any of the sources (Bundler::VersionConflict)

編輯： 我做 「捆綁檢查」，我得到這個

/Library/Ruby/Site/1.8/rubygems.rb:779:in `report_activate_error': Could not find RubyGem bundler (>= 0) (Gem::LoadError) 
    from /Library/Ruby/Site/1.8/rubygems.rb:214:in `activate' 
    from /Library/Ruby/Site/1.8/rubygems.rb:1082:in `gem' 
    from /usr/bin/bundle:18 

EDIT2：

Ø凱，這是我成功安裝rmagick後關閉的最新錯誤。我能夠做rake db：創建和遷移。我試圖做軌道服務器（使用Rails3中），我得到這個錯誤

應用程序要求沒有安裝，在這種情況下，創業板的「硒的webdriver。」嘗試bundle check以查看是否有其他錯誤，然後繼續安裝缺少的寶石。

編輯從評論：

在你的第一個代碼塊你使用MRI 1.9，那麼你就轉移到MRI 1.8，現在你突然使用稀土元素。這告訴我你的計算機上至少有三個不同的Ruby解釋器，這不會讓你的生活變得更輕鬆。在所有可能的情況下，你也有各種寶石。你有使用RVM的經驗嗎？如果沒有，我的建議是刪除RVM，堅持使用一個Rails解釋器（系統默認值，MRI 1.8）並從那裏開始。

對於Rails開發人員來說，安裝rmagick幾乎是一個傳言。起初它很可怕，但最終並不複雜。在本地編譯過程中，真正想要看到的是ImageMagick的安裝。

在Linux上，無論使用哪個軟件包管理器，我都會很幸運。例如，sudo apt-get install imagemagick。

如果你是在OS X上，那麼這是一個更多的工作。我多次使用了port，最近我使用了brew來安裝ImageMagick。如果您使用的是OS X，那麼請前往Google，並使用您正在使用的任何軟件包管理系統搜索指令。
