全新应用中服务器上的Rails’parse_query’错误
我在OS X 10.10.3上安装：自制软件，命令行工具，然后使用rbenv安装ruby：
ruby 2.2.2p95 (2015-04-13 revision 50295) [x86_64-darwin14] Rails 4.2.2 当我创建一个新的应用程序（使用默认的sqlite数据库）并尝试运行它时，它说：
=> Booting WEBrick => Rails 4.2.2 application starting in development on http://localhost:3000 => Run `rails server -h` for more startup options => Ctrl-C to shutdown server [2015-06-18 23:11:30] INFO WEBrick 1.3.1 [2015-06-18 23:11:30] INFO ruby 2.2.2 (2015-04-13) [x86_64-darwin14] [2015-06-18 23:11:30] INFO WEBrick::HTTPServer#start: pid=41860 port=3000
但在浏览器中我看到：

有人有类似的错误吗？ 你是怎么解决的？
我得到了相同的东西，但使用Rails 4.2.1，并在Puma 2.11.3上运行。
我注意到Bundler刚刚将机架升级到1.6.3。 将版本设置回1.6.2可以解决它。
问题出在这里： https ： //github.com/rails/rails/issues/20624
要解决它，请更改您的Gemfile：
gem 'rack', '1.6.1'
