Question

我对stackoverflow post Github link提出了几乎相同的问题，但在我的案例中似乎都没有帮助。我解释原因。一切都在我的本地机器和heroku测试实例上工作得非常好，然后突然我将代码推送到带有消息的heroku测试实例上

“应用程序错误”

我检查了日志并发现了错误

`require'：无法加载此类文件 - simplecov（LoadError）

完整的日志在

之下

/app/vendor/bundle/ruby/2.2.0/gems/activesupport-4.2.5.1/lib/active_support/dependencies.rb:274:in NONE TOTAL, NOT SPECIFIED ALL CLASSES WINTER SPRING, (EXCL DURUM) ALL CLASSES IRRIGATED IRRIGATION METHOD NON-IRRIGATED IRRIGATION STATUS阻止在'来自' /app/vendor/bundle/ruby/2.2.0/gems/activesupport-4.2.5.1/lib/active_support/dependencies.rb:240:in require': cannot load such file -- simplecov (LoadError) from /app/vendor/bundle/ruby/2.2.0/gems/activesupport-4.2.5.1/lib/active_support/dependencies.rb:274:in需要'来自 /app/vendor/bundle/ruby/2.2.0/gems/codeclimate-test-reporter-1.0.1/lib/code_climate/test_reporter/formatter.rb:7:in `'

而我的load_dependency' from /app/vendor/bundle/ruby/2.2.0/gems/activesupport-4.2.5.1/lib/active_support/dependencies.rb:274:in工作正常。我查看了更多日志，发现heroku正试图在localhost中查看simplecov文件，而我在我的gemfile中明确提到了rvm ruby 2.2.0。这似乎是一个错误原因。我无法将整个应用程序降级到2.2.4，因此我尝试了许多解决方案，例如2.2.0，并删除并重新安装bundle update rspec但所有徒劳。任何帮助都会非常感激

更新：下面是我的gemfile测试组

simplecov

我运行了以下命令

出现

和上述错误

Answer 1

SimpleCov是一种代码覆盖工具，可以在本地计算机或CI（如Travis CI）上运行。它不应该在用于生产或分期的Heroku上运行。

您应该将simple_cov和任何与测试相关的宝石放在gemfile的test组中：

group :test do
  gem 'simplecov', '~> 0.12.0'
end

运行bundle以重新生成Gemfile.lock并提交结果。通过推送更改将应用程序重新部署到Heroku。

更新

您的Gemfile在测试组之外有gem 'codeclimate-test-reporter'。这导致了这个错误。您还有listen，这也是一个不适合生产的工具。

所有环境中所需的所有gem都应放在Gemfile的顶部，然后列出组。

首选使用group选项将宝石置于组块中。一般来说，在添加依赖项时要更加小心，不要让你的Gemfile变得一团糟，因为这就是你最初如何解决这些问题。
