Uninstalling Xcode 3.2.6 from Lion 10.7.2

Question

I've installed xCode 3.2.6 on my Lion 10.7.2.

After install I can't find the xCode icon to launch it. I've got to know 3.2.6 doesn't support Lion.

However, the worst thing happen when I tried to uninstall it with

sudo /Developer/Library/uninstall-devtools --mode=all

Unfortunately uninstall-devtools wasn't there. I'm stuck middle of nowhere.

Does anybody have any idea how to uninstall it and install xCode 4.2?

Answer 1

Following command fire on terminal and remove the all files and folder of xcode

sudo /Developer/Library/uninstall-devtools --mode=all

also more information and show log of the uninstal so go refrence link here

Answer 2

If /Developer/Library/uninstall-devtools does not exist skip that step.

Delete the /Develop folder if it exists.

Install xCode 4.2. Th eXcode icon will be in /Developer/Applications

The Xcode latest beta is even easier to install, get it if you have access.

Answer 3

If you install Xcode 3 from the GUI on Lion, you'll end up with a bunch of random tools but not the actual Xcode Toolset. In that case, you can use the uninstall-dev-tools located in /Library/Developer/Shared (rather than /Developer/Library).

You can fully install XCode 3 on Lion via the Terminal with the following commands:

export COMMAND_LINE_INSTALL=1
open "/Volumes/Xcode and iOS SDK/Xcode and iOS SDK.mpkg"

Answer 4

careful: if you work in ruby, you better stay with xCode 4.1
