配置的前提條件：ruby on rails（ruby1.9.2 和rails 3.07） 完整的開發(fā)環(huán)境已經(jīng)配置好，jdk1.5或1.6，eclipse3.5已安裝完畢并能正確運(yùn)行。
You should also make sure that your login PATH is set up correctly such that you can execute the ruby, gem, rails, and git commands correctly. Setting these things up in your .bashrc (or equivalent) isn't sufficient, because it doesn't get evaluated by default when GUI applications like Aptana Studio 3 get launched.
Ruby switching utilities like rvm should also work, provided that you set them up in your login PATH as well.
安裝過程很簡單：
1.打開eclipse在幫助按鈕（Help）中選擇安裝新軟件（Install New Software）
2.在彈出的可選軟件（Available Software）對話框中點擊添加按鈕（Add..）
3.在彈出的對話框中Name處輸入Aptane3(這個名字可以隨便填)，在Location處輸入網(wǎng)址：
http://download.aptana.com/studio3/plugin/install按后點確定（OK）按鈕回到可選軟件（Available Software）對話框，稍等一下會看到Aptana Studio 3 選中它并點下一步（next）然后需要等一段時間進(jìn)入license page，選擇接受協(xié)議，并點完成（Finish），之后就是一段漫長的等待了。最終安裝成功重啟eclipse。搞定！
