我找到了一些与我相关的帖子......但现有的答案都没有奏效......所以这是一个来自 Newbee 的新帖子：

我刚刚安装了 Ubuntu 12.10 并尝试按照各种教程（http://rubyonrails.org/download）在 Rails 上安装 Ruby，我什至尝试了 RVM ......所以最后当我尝试启动我的服务器时，我的 localhost:3000 是不工作。

这是我启动服务器时的终端：

laslo@ubuntu:~$ rails s
/usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require': iconv will be deprecated in the future, use String#encode instead.
/usr/lib/ruby/vendor_ruby/railties/lib/rails_generator/generators/applications/app/app_generator.rb:7: Use RbConfig instead of obsolete and deprecated Config.

导轨 3+

bundle exec script/rails server从项目根目录尝试。

例如

durrantm.../linker$ bundle exec script/rails server
=> Booting WEBrick
=> Rails 3.1.8 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
[2013-04-08 21:48:24] INFO  WEBrick 1.3.1
[2013-04-08 21:48:24] INFO  ruby 1.9.3 (2012-11-10) [i686-linux]
[2013-04-08 21:48:24] INFO  WEBrick::HTTPServer#start: pid=9187 port=3000

导轨 2

从项目根目录：

$ script/server
=> Booting WEBrick
=> Rails 2.3.8 application starting on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
[2013-04-08 21:58:11] INFO  WEBrick 1.3.1
[2013-04-08 21:58:11] INFO  ruby 1.9.3 (2012-11-10) [i686-linux]
[2013-04-08 21:58:11] INFO  WEBrick::HTTPServer#start: pid=10473 port=3000

如果失败，也许可以重新开始：

cd                  # Go to your home directory
rails new abc       # Create the app
cd abc              # cd into the project's directory.
                    # Change the config/database.yml if desired.
script/rails server # for rails 3 or use the rails 2 command above.

更多版本信息：

Ruby，您应该使用 1.9.2+ 大多数人现在使用 1.9.3+。
我建议您使用 RVM 来维护您的 ruby​​ 版本。其他人也使用 rbenv。

rvm: https://rvm.io/ # 是的，这是一个真实的 URL！
rbenv：https ://github.com/sstephenson/rbenv/

Rails 你应该在 rails 3.1+ 检查rails -v
你可以安装一个较新的版本，并gem install rails使用-v 3.1.2来指定那个版本。

Rails 服务器适用于特定的应用程序。您在根路径中启动了 rails sever，当然这不起作用。

您首先需要创建一个新应用程序。

$ rails new myapp
$ cd myapp
# Install the gems needed at first
$ bundle install
# Then start server
$ rails s

添加

从您的代码中，我发现真正的原因是您使用的是 Ruby 1.9.1。您刚刚下载的最新 Rails 不支持此版本。

尝试至少将 Ruby 升级到 1.9.3。

你的 Ruby 版本是什么？Ruby-v显示它？你应该首先执行这些命令。

bundle update
bundle install

我和你有同样的问题，这就是我解决这个问题的方法。在您创建的项目的 cd 中键入script/server 。一世
