当我练习 Ruby on Rails 教程的第三章时。在大多是静态页面之后：结论。我试图将我的应用程序推送到heroku，但出现如下错误：（我到处搜索此错误但无法找到解决方案）

我的 Gemfile 是这样的：

source 'https://rubygems.org'

gem 'rails', '3.2.8'

gem 'sqlite3', :group => [:development, :test]

gem 'rb-fsevent', '~> 0.9.1'
gem "ZenTest", "~> 4.8.2"
gem 'rake', '~> 0.8.7'

group :development, :test do
  gem 'guard-spork', '1.2.0'
  gem 'spork', '0.9.2'
end

group :production do
  gem 'thin'
  gem 'pg'
end

group :assets do
  gem 'sass-rails',   '~> 3.2.3'
  gem 'coffee-rails', '~> 3.2.1'
  gem 'uglifier', '>= 1.0.3'
end

gem 'jquery-rails'

group :development do
  gem 'rspec-rails', '2.11.0'
end

group :text do
  gem 'rspec', '2.11.0'
  gem 'webrat', '0.7.2'
end

我不知道这个应用程序有什么问题。我更改了 Zentest 版本并投入测试或生产，它没有工作。

ZenTest 似乎限制了允许的最新 ruby​​gems。它的解决方案是更新 ZenTest 以及 ruby​​gems，因为最新的 ZenTest 似乎工作得更好。
