Question

我正在尝试在我的开发环境（Ubuntu 14.04）上运行Ruby on Rails应用程序。 rails s不报告错误，Webrick似乎正常启动：

$ rails s
=> Booting WEBrick
=> Rails 3.2.13 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
[2015-04-30 08:52:32] INFO  WEBrick 1.3.1
[2015-04-30 08:52:32] INFO  ruby 1.9.3 (2014-11-13) [x86_64-linux]
[2015-04-30 08:52:32] INFO  WEBrick::HTTPServer#start: pid=15523 port=3000

但是，一旦我尝试通过Web浏览器访问应用程序，Webrick崩溃时出现以下错误：

/home/desousa/.rvm/rubies/ruby-1.9.3-p551/lib/ruby/1.9.1/webrick/server.rb:98: [BUG] Segmentation fault
ruby 1.9.3p551 (2014-11-13 revision 48407) [x86_64-linux]

我在这个项目中使用的软件版本：

$ ruby -v
ruby 1.9.3p551 (2014-11-13 revision 48407) [x86_64-linux]

$ rails -v
Rails 3.2.13

这可能是什么原因？或者我可以了解原因吗？

Answer 1

我对Webrick也有一些麻烦，导致了一个分裂错误。我只在一个特定的ubuntu盒子上有这个，但我在其他ubuntu盒子上没有相同的错误，具有完全相同的设置。最近我用thin解决了它。为此，请将此添加到Gemfile：

gem 'thin'

然后运行

bundle install
rails server

Webrick在第一页加载时因Segmentation Fault崩溃
