每次我尝试运行rake spec或bundle exec rspec spec出现 Permission denied - bind(2)错误时。痕迹：

cloud9 是否支持规范？

我能够在 cloud9 上运行 mini-test、test::unit 和 rspec 测试。我认为您遇到的错误是由于 spork 或尝试使用 drb （带有警卫或其他东西）

我试图让它也能正常工作，但我无法让 spork 绑定到 $PORT，而且似乎不允许您绑定到任何其他端口。

我也无法让警卫正常工作。它会看到文件已更改，但在运行规范时，我收到有关未知开关 -f -r -out 的错误。对此的研究指向捆绑器，并且可能需要在将命令发送到系统之前将它们用引号括起来。（也许）

如果你摆脱了任何与 drb 或 spork 相关的东西，我敢打赌你的测试会奏效。
