Heroku问题:您要查找的页面不存在

Question

我按照书直到第5章完成,当我推送到Heroku时,它在我的linux工作站上工作正常,所有数据都正确推送但是当我尝试打开Heroku时(http://vivid-sky-685.heroku.com)

我收到了404消息.

您要查找的页面不存在.您可能输错了地址或页面可能已移动.

以下是我Gemfile的申请

source 'http://rubygems.org'
gem 'rails', '3.0.5'
gem 'sqlite3'

group :development do
  gem 'rspec-rails', '2.5.0'
end

group :test do
  gem 'rspec', '2.5.0'
  gem 'webrat', '0.7.1'
  gem 'spork', '0.9.0.rc4'
end

gem 'rake','~> 0.8.7'

什么想法可能会出错？

@odin这是我的heroku日志,谢谢

Answer 1

我知道这是一个老问题,但我也碰到了它.我意识到config/routes.rb在推动之前我没有改变根路线.不改变它可能会导致本地欢迎页面,但在heroku上它将得到上述错误.

Answer 2

我遇到了同样的问题; 然而,改变production.rb的1个代码后位于config/environments/production.rb从

config.assets.compile = false

至

config.assets.compile = true

提交新的变化.然后我的示例应用程序在heroku上工作正常

Answer 3

我正在使用postgresql,而且我的页面也没有显示在heroku上.

这个命令修复了它:

heroku run rake db:setup

然后

heroku rake db:migrate

我之前已经迁移过,但是没有先完成设置.

我也尝试过设置

config.assets.compile = true

在production.rb中,但没有区别.
