解决Xcode 4.0.1 and iOS SDK4.3安装后无法启动Xcode!

我是用虚拟机安装的Mac OS X 10.6.6并更新到10.6.8
Xcode 4.0.1 and iOS SDK4.3

安装一切正常，我以为都OK了``可是当我要运行Xcode时，
却提示“由于某个问题，Xcode不能打！”

　　弄了半天搞不定，不知是什么原因，害得我又是重装系统又是重装xcode,还是不行。后来在国外外网站上看在一个帖子，总算弄明白了。原来是xcode的路径不正确。
　　xcode安装成功后，为了每次能够快速打开，我把在/developer/Applications/目录中的xcode拖放到屏幕下方工具栏的“应用程序”文件夹里面，路径错了！其实直接拖放到工具栏上就行了。有时拖放到桌面上也会遇到此问题。

anyone seen this before?

Macpomme回复：
Where did you install XCode?

Older versions, I believe, had to be installed into a specific location.

RomanT 追问：
Steve - I reinstalled it last night, to no avail.

Venom - default directory. This is the latest xcode from my knowledge.

I don't use it - but I don't like things not working, so I want to fix it, just in the case I decide to tinker with it one day.

Steve Joynt 回复：
My XCode is in /Developer/Applications, but from the error message it looks like yours is in /Applications. Did you move it by any chance? Are you running Leopard?

RomanT 回复：
Steve - you're the man!

I was playing with aliases, and obviously ended up having a copy in my /Applications folder. I use Quicksilver, and always asked for XCode, and by default it just grabbed on from /Applications as opposed to /Developer/Applications.

all is good now.

Many thanks.
