安装RVM：同步本地端口树失败rsync

Question

我是Ruby新手，并且正在使用终端。我安装了rvm，但我似乎无法安装Ruby 1.9.3。这个问题似乎与rsync和端口树同步。我不知道这是什么意思。

我试过寻找其他的解决方案，但没有一个与rvm相关（我可以理解，他们都只关注autoupdated macports自身）。我也看到了有关proxys的一些事情，但是如果那是真的，我不知道我需要做什么。他们都主要关注macports，并使用诸如“sudo”或-d这样的词语进行环绕，当我试图安装Ruby时，我不知道该如何做。以下是我得到：

$ rvm install 1.9.3 
Searching for binary rubies, this might take some time. 
No binary rubies available for: osx/10.7/x86_64/ruby-1.9.3-p429. 
Continuing with compilation. Please read 'rvm mount' to get more information on binary rubies. 
Installing requirements for osx, might require sudo password.

我试着使用一些关键字/答案我在最后，这也解释了./port线下线上看到的。我从xcode安装了命令行。安装自制软件可以解决这个问题吗？我会很感激任何帮助！

确保下面的命令正确

运行

port selfupdate 

，然后再次尝试
