但是安装了好多次都没有出现提示，均告失败！
今天再次鼓起勇气安装试试：
首先安装Komodo-Edit-4.3.2-1263; 成功！
然后：
下载extjs_api_catalogs-2.0.2-ko.xpi ；
http://community.activestate.com/komodo-extension/extjs-api-catalog-collection
to install it and let komodo edit manage its update in future releases:
1. open up tools --> extension manager
2. wait for the extension manager's dialog to open then click on install on the bottom left
3. select the xpi file you just download
4. another dialog will open so that you may install it. the dialog is the same as when you add extensions to Firefox.
5. restart Komodo
to activate it:
1. open up edit --> Preferences
2. click on Code Intelligence on the left menu
3. select either ExtJs v111 or ExtJs 2.0 by clicking in the little space on the left.
对于执行到to activate it 时就找不到cix文件，所以需要下载，好不容易找到
这是地址：http://community.activestate.com/forum-topic/javascript-extjs-yui-ext（也许是自己有些笨吧，呵呵）
然后就可以 对照to activate it:得步骤进行安装了；
现在安装完成！重启后进行测试看是不是能有提示出现，期待中！
测试成功！提示出现！哈哈！
