安裝RVM：同步本地端口樹失敗rsync

Question

我是Ruby新手，並且正在使用終端。我安裝了rvm，但我似乎無法安裝Ruby 1.9.3。這個問題似乎與rsync和端口樹同步。我不知道這是什麼意思。

我試過尋找其他的解決方案，但沒有一個與rvm相關（我可以理解，他們都只關注autoupdated macports自身）。我也看到了有關proxys的一些事情，但是如果那是真的，我不知道我需要做什麼。他們都主要關注macports，並使用諸如「sudo」或-d這樣的詞語進行環繞，當我試圖安裝Ruby時，我不知道該如何做。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.

我試着使用一些關鍵字/答案我在最後，這也解釋了./port線下線上看到的。我從xcode安裝了命令行。安裝自制軟件可以解決這個問題嗎？我會很感激任何幫助！

確保下面的命令正確

運行

port selfupdate 

，然後再次嘗試
