测试在我的Ubuntu pc上运行，但不在我的Mac OS X Lion 10.7.3，Ruby 1.9.3，Rails 3.2.1上运行

Question

我在Dropbox和两台运行的笔记本电脑上有一个项目：一个是Ubuntu，另一个是Mac OS X Lion 10.7.3。 当我尝试在ubuntu上运行rspec或者黄瓜时它们运行良好，但是当我尝试在Mac上运行测试时，我在config / application.rb中 Bundler.require(*Rails.groups(:assets => %w(development test)))了相同的错误：13： Bundler.require(*Rails.groups(:assets => %w(development test)))

黄瓜：

Using the default profile...

我该如何解决？ 任何帮助赞赏。 谢谢。

Answer 1

问题出在我的Gemfile中的两个宝石中：

gem 'rb-inotify', '0.8.8'
gem 'libnotify', '0.5.9'

据我所知，这些宝石只与Ubuntu兼容。

UPD：

您应该将特定于操作系统的宝石添加到组中。 将所有OS X特定的gems添加到Gemfile中的darwin组，并将所有特定于Linux的gem添加到linux组：

# Gemfile
group :darwin do
  gem 'rb-fsevent'
  gem 'growl'
end

group :linux do
  gem 'rb-inotify'
end

要在正确的环境中需要适当的gem，请将以下内容添加到config / application.rb ：

platform = RUBY_PLATFORM.match(/(linux|darwin)/)[0].to_sym
Bundler.require(platform)

Answer 2

我的宝石有问题。

更新捆绑包

正确阅读错误，它会告诉你哪个宝石是罪魁祸首。

事实是，并非所有宝石都与操作系统兼容。
