每当我尝试运行rake spec或bundle exec rspec spec时，我都会收到Permission denied - bind(2)错误。

是否支持cloud9规范？
答案 0 :(得分：0)
我能够在cloud9上运行mini-test，test :: unit和rspec测试。 我认为你得到的错误要么是因为spork还是试图使用drb（带警卫或其他东西）
我试图让它也能正常工作，但我无法将spork绑定到$ PORT，而且似乎不允许绑定到任何其他端口。
我也无法得到正确的工作。它会看到文件发生了变化，但是当运行规范时，我收到了有关Unknown开关-f -r -out的错误。对它的研究指向了bundler，并且可能需要在将命令发送到系统之前将命令包装在引号中。 （也许）
如果你摆脱任何与drb或spork相关的东西，我打赌你的测试会有效。
