使用 rspec 和 autospec 运行第二个规范后出错

Question

安装 rspec/ZenTest 并运行 autospec 后，它会按预期第一次运行我的规范。在对我的一项规格进行更改并第二次运行时，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知道这里到底发生了什么？

谢谢

进度栏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 分叉进程会继承 STDOUT 文件描述符，但无法写入它，因此会引发管道错误。

尝试从 RSpec 帮助程序中删除进度条。或者，尝试在 fork 后重新初始化进度条插件。
