rails应用程序未部署到heroku（应用程序错误消息）

Question

我正在尝试将一个简单的hello world Rails应用程序部署到Heroku，但是我遇到了一个应用程序错误。奇怪的是它对我的其他Rails应用程序工作正常，但它对这一个不起作用，即使我对两者做了相同的更改，包括具有相同的Gemfile，控制器操作和根路由。它在本地工作正常，但在部署时却没有。

这是运行heroku run rails console和heroku logs时的错误输出。

非常感谢任何帮助，找出我收到此错误的原因。

这是我的Gemfile.lock：

BUNDLED WITH
   1.10.6

这是spring gem文件

#!/usr/bin/env ruby

# This file loads spring without using Bundler, in order to be fast.
# It gets overwritten when you run the `spring binstub` command.

unless defined?(Spring)
  require 'rubygems'
  require 'bundler'

  if (match = Bundler.default_lockfile.read.match(/^GEM$.*?^    (?:  )*spring \((.*?)\)$.*?^$/m))
    Gem.paths = { 'GEM_PATH' => [Bundler.bundle_path.to_s, *Gem.path].uniq }
    gem 'spring', match[1]
    require 'spring/binstub'
  end
end

您可能不需要在here

中包含弹簧测试组

仅将其保留在开发组下。

你的gemlock中的spring版本也是1.4.3而heroku抱怨1.4.2。也许你需要在你的gemfile中明确指定一个版本，删除你的Gemfile.lock（不应该总是这样），再次运行bundle，提交你的更改并重新部署。
