Rails服務器已啓動，但localhost：3000顯示錯誤

Question

我剛剛在http://rubyinstaller.org/上安裝了Ruby on Rails軟件包（這是我第一次嘗試在我的xp sp3系統中設置ruby on rails工作站）。安裝過程完美無缺。我使用它的控制檯啓動了服務器。服務器已啓動，但http：// localhost：3000顯示錯誤頁面（未找到頁面）。 我在控制檯中顯示如下：我錯過了什麼？

和控制檯輸出在服務器啓動是：

Description: 
    The 'rails new' command creates a new Rails application with a default 
    directory structure and configuration at the path you specify. 

    You can specify extra command-line arguments to be used every time 
    'rails new' runs in the .railsrc configuration file in your home directory. 

    Note that the arguments specified in the .railsrc file don't affect the 
    defaults values shown above in this help message. 

Example: 
    rails new ~/Code/Ruby/weblog 

    This generates a skeletal Rails installation in ~/Code/Ruby/weblog. 
    See the README in the newly created application to get going.

Answer 1

您在創建Rails項目的目錄必須cd，然後rails s應該工作正常。

這也意味着服務器尚未啓動。請仔細閱讀控制檯命令的輸出，大部分時間他們會告訴您他們的工作，或者他們爲什麼不按預期工作。

Answer 2

服務器未啓動。您需要導航到你的Rails應用程序文件夾，安裝所需的寶石並啓動服務器：

所有你需要創建一個新的Rails項目的

cd <your app folder> 
bundle install 
rails s 

Answer 3

第一。我認爲C：/ Sites不是你的rails項目目錄。

rails new test_app 

它會在您的目錄中創建一個rails項目。比去cd test_app。並嘗試啓動您的服務器。 希望它能起作用。

Answer 4

謝謝大家。最後我得到了它的工作。問題是我的test_app文件夾中的Gemfile。我評論了該行gem'uglifier'，'> = 1.0.3'，我得到了它的工作。希望它能進一步發揮作用，讓我繼續前進。
