Heroku：您正在寻找的页面不存在 [英] Heroku: The page you were looking for doesn't exist

问题描述

当我尝试将我的应用程序部署到Heroku时，出现此错误。我的第一个部署工作正常之前，我正在做 heroku运行rake db：reset 。
在此之后，我有以下错误：我们很抱歉，但出错了。和您正在寻找的页面不存在，您可能错误输入了地址或页面可能已移动。

我的heroku日志说：

  2012-12-08T11：40：54 + 00：00 app [web.1]：ActionView :: Template :: Error（bootstrap .css未预编译）：
 2012-12-08T11：40：54 + 00：00 app [web.1]：9：<％= csrf_meta_tags％> 
 2012-12-08T11：40：54 + 00：00 app [web.1]：
 2012-12-08T11：40：54 + 00：00 app [web.1]：8： <％= javascript_include_tagbootstrap，media：all％> 
  

有人，你能帮我吗？

解决方案

看起来Heroku抱怨你的资产没有预编译。我通过本教程阅读了有关heroku的rails，到资源预编译。

您可以告诉您的应用程序预编译生产中的资产。

 ＃config / environments / production.rb 
 config.assets.compile = true 
＃Heroku也要求这是false 
 config.assets.initialize_on_precompile = false 
  

或者您可以使用rake任务预编译您的资产

 ＃在推向Heroku之前，然后您可以推送
 rake资产：预编译
 
＃或者推到heroku后b 
 heroku运行rake资源：预编译
  

I get this error when i try to deploy my app to Heroku. My first deployment works fine before I'm doing heroku run rake db:reset. After this, I have errors below: "We're sorry, but something went wrong." and "The page you were looking for doesn't exist. You may have mistyped the address or the page may have moved."

My heroku logs says:

2012-12-08T11:40:54+00:00 app[web.1]: ActionView::Template::Error (bootstrap.css isn't precompiled):
2012-12-08T11:40:54+00:00 app[web.1]:     9:   <%= csrf_meta_tags %>
2012-12-08T11:40:54+00:00 app[web.1]: 
2012-12-08T11:40:54+00:00 app[web.1]:     8:   <%= javascript_include_tag "bootstrap", media: "all"%>

Some one, Can you help me ?

解决方案

Looks like Heroku is complaining that your assets are not precompiled. I'd read through this tutorial about rails on heroku, there is a section dedicated to resource pre-compilation.

You can tell your application to precompile assets in production

#config/environments/production.rb
config.assets.compile = true
# Heroku also requires this to be false
config.assets.initialize_on_precompile=false

Or you can precompile your assets using the rake task

#before pushing to Heroku and then you can push
rake assets:precompile

#or after you've pushed to heroku
heroku run rake assets:precompile
