Question

我发现了一些与我相关的帖子......但现有的答案都没有...所以这里有一个来自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，我甚至尝试过RVM ......所以最后当我尝试启动我的服务器时我的localhost：3000不是工作

启动服务器时，这是我的终端：

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.

有什么想法吗？当然，我错过了一些巨大的东西......但是又是什么？

Answer 1

Rails 3 +

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

e.g。

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

Rails 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，可能会重新开始：

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，你应该是1.9.2+现在大多数人都在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，这是一个真实的网址！ rbenv：https://github.com/sstephenson/rbenv/

你应该在轨道上的轨道3.1+检查rails -v
您可以使用gem install rails使用-v 3.1.2安装较新版本以指定该版本。

Answer 2

Rails服务器适用于特定应用。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。

$ 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。

Answer 3

什么是Ruby的版本？Ruby-v显示它？你应该在第一个这些命令时做。

bundle update
bundle install

Answer 4

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 。我

无法运行localhost：3000（Ubuntu 12.10）
