Heroku上的Rails 3.1.3：（没有路由匹配[GET]“/assets/rails.png”） [英] Rails 3.1.3 on Heroku: (No route matches [GET] "/assets/rails.png")

问题描述

我已经在Heroku上安装了几个基本的应用程序，没有问题，而且这个（Rails 3.1.3）看起来很好，因为它显示了Rails欢迎页面

I've installed a few basic apps on Heroku without problem, and this one (Rails 3.1.3) seemed fine in that it showed Rails welcome page

public/index.html.erb

但是当我删除那个页面然后设置

but when I removed that page and then set

root :to => 'users#index'

我遇到了问题。在heroku日志中，它表示存在路由错误

I got a problem. In the heroku logs it said there's a routing error

ActionController::RoutingError (No route matches [GET] "/assets/rails.png"):

有谁知道这是关于什么的？

Does anyone know what this is about?

推荐答案

在推送到Heroku之前没有预编译您的资源，请尝试：

It looks like you may not have precompiled your assets before you pushed to Heroku, try:

rake assets:precompile
git add .
etc etc

我认为这应该有所帮助。有关详情，请参阅此处： http://devcenter.heroku.com/articles/rails31_heroku_cedar

I think that should help. For more information, see here: http://devcenter.heroku.com/articles/rails31_heroku_cedar
