Ruby on rails 设置RVM时的Macports问题

在一台新的笔记本电脑上安装rails和RVM，我在运行时遇到了这个错误

Error running 'requirements_osx_port_update_system ruby-2.0.0-p247',
please read /Users/#####/.rvm/log/1380821805_ruby-2.0.0-p247/update_system.log
Requirements installation failed with status: 1.

当运行此

sudo rvm install ruby

它产生了这个代码

我已经安装了Xcode和Xcode命令行工具。以前有人修复过类似的问题。

您需要确保可以首先运行此命令：

sudo port -dv selfupdate

这可能是暂时的网络问题-如果没有按照显示的说明进行操作。

意识到可能是某些网络配置在工作中阻塞了端口。检查您的网络权限或尝试其他网络。
