尝试在openshift中转发端口时权限被拒绝

Question

我是openshift的新手，我正试着尝试一下。同时按照this教程运行rhc port-forward -a命令。我收到了一个权限被拒绝的错误。你知道我做错了什么吗？

问题不在于密码。如果您输入了错误的密码，则会收到不同的错误消息

谢谢

看起来您运行的是较旧版本的rhc客户端工具(1.2.7)。请在更新您的客户端工具(gem update rhc)后重试。

该错误指示您的主机无法绑定特定的本地端口，可能是因为该端口正在使用中。最新的rhc客户端通过绑定到下一个打开的端口来响应。如果您在更新后仍有问题，请让我们知道。
