开始新的铁路博客时覆盖提示

Question

当我进入时

    rails new blog

返回

    exist  
       identical  README.rdoc
       identical  Rakefile
       identical  config.ru
       identical  .gitignore
       identical  Gemfile
           exist  app
       identical  app/assets/images/rails.png
       identical  app/assets/javascripts/application.js
       identical  app/assets/stylesheets/application.css
       identical  app/controllers/application_controller.rb
       identical  app/helpers/application_helper.rb
           exist  app/mailers
           exist  app/models
       identical  app/views/layouts/application.html.erb
       identical  app/mailers/.gitkeep
       identical  app/models/.gitkeep
           exist  config
       identical  config/routes.rb
       identical  config/application.rb
       identical  config/environment.rb
           exist  config/environments
       identical  config/environments/development.rb
       identical  config/environments/production.rb
       identical  config/environments/test.rb
           exist  config/initializers
       identical  config/initializers/backtrace_silencers.rb
       identical  config/initializers/inflections.rb
       identical  config/initializers/mime_types.rb
        conflict  config/initializers/secret_token.rb
    Overwrite /Users/user/blog/config/initializers/secret_token.rb? (enter "h" for help)    [Ynaqdh] 

无论我点击 y/yes 还是 n/no，它都会安装捆绑包，并且

    cd blog

命令通过-但是当我尝试时

    rails server

我明白了

    [2012-06-06 19:21:59] WARN  Could not determine content-length of response body. Set     content-length of the response or set Response#chunked = true

[2012-06-06 19:22:00] WARN 无法确定响应正文的内容长度。设置响应的内容长度或设置 Response#chunked = true

我发现你应该在某个地方安装“瘦”gemfile 来解决这个问题，然后运行

    rails server thin

然后返回

    /Users/user/.rbenv/versions/1.9.3-p125/lib/ruby/gems/1.9.1/gems/rack-1.4.1/lib/rack/handler/thin.rb:1:in `require': cannot load such file -- thin (LoadError)

然后“localhost :3000”显示一个糟糕的页面，说它找不到该页面，但是当我输入常规服务器命令时，页面完好无损，但警告阻止我继续前进。

有什么想法吗？

感谢 Dty- 注意 n00bs，您需要在单独的窗口中运行服务器和代码（我现在感觉很慢）

Answer 1

您在使用rails server 时看到的警告是正常的。请注意，它们只是警告，因此不应有任何事情阻止您继续前进。

如果您使用瘦服务器，那么正确的命令应该是thin start。如果您使用的是 rails 3.2rc2，那么如果 gem 'thin' 在您的 Gemfile 中，则 according to this、rails server 将起作用。
