aptana 安裝emmet出錯

因為一直用zen-coding，最近才去安裝emmet

但安裝時出現下列錯誤


Cannot complete the install because of a conflicting dependency.
  Software being installed: Emmet for Eclipse 1.0.0.201303162055 (io.emmet.eclipse.feature.group 1.0.0.201303162055)

查詢過程：

Looks like emmet wants org.eclipse.core.expressions 3.4.300 which is in Indigo and you have Helios.

JiRybar: I'll try to update my Eclipse and try to install Emmet again.

解法：
因為aptana一陣子沒更新了
所以點 Help->Check for Update 更新aptana 後重開
照其他網頁教學就能安裝emmet了

附上安裝教學：

sublime 安裝emmet

有時候會安裝不成package controll ，隔一天就好了..
就如同 這個安裝教學網站有時候會掛掉一樣...

emmet跳到相對應的html tag( go to matching pair ):
sublime熱鍵 ctrl+alt+j
aptana 熱鍵 無預設，自己設定
