每个其他页面重新加载我得到500个未找到的内部错误资产：

GET http://localhost:5000/assets/application-ddb2488b062b582487dc9a71475f69b3.css?body=1 
GET http://localhost:5000/assets/application-89761eef2e06fafdfbe675623cff99d7.js?body=1

解决方法

是的,它似乎是一个错误(或不是？).资产预编译时： 
RAILS_ENV=production bin/rake assets:precompile

在config / environments / development.rb中：

config.assets.digest = true

因为在Rails 4.2(Release Notes,Pull Request)中默认是正确的,你将在开发环境中得到这个错误,无论你使用什么服务器(我在WEBrick和Thin都得到它).据我所知,它试图从/ public / assets获得预编译资产,但由于失败而失败

Content-Type header found in 304 response,not allowed

或类似的东西.

每次开始开发时,都可以通过清理/ public / assets来避免这种行为：

bin/rake assets:clobber

或者在开发配置中关闭资产摘要：

config.assets.digest = false

或者通过关闭在开发配置中提供的静态资产：

config.assets.digest = true
config.serve_static_assets = false
