ruby-on-rails - 使用 rspec 和 autospec 运行第二次规范后出错

Question

安装 rspec/ZenTest 并运行 autospec 后，它按预期第一次运行了我的规范。在对我的一个规范进行更改并在第二次运行时，我得到以下结果:

/usr/bin/ruby1.8 /usr/lib/ruby/gems/1.8/gems/rspec-1.3.0/bin/spec --autospec /home/schambers/Projects/notebook/spec/models/user_spec.rb -O spec/spec.opts

    from /usr/lib/ruby/gems/1.8/gems/rspec-1.3.0/bin/spec:5

有没有人遇到过这个或者知道这到底是怎么回事？

谢谢

Progress Bar 正在尝试将内容打印到 TTY，以便它可以在运行测试时向您显示漂亮的规范进度输出。我猜测使用 autospec fork 进程继承了 STDOUT 文件描述符，但无法写入它，因此它会抛出管道错误。

尝试从 RSpec 助手中删除进度条。或者，尝试在 fork 后重新初始化进度条插件。
