Xcode 4 install errors

Use 'Activity Monitor', locate and stop iTunes Helper then try the installer again.

Also note that Xcode 3.2.6 works fine for me w/Lion after doing the required JAVA update.

I have the same issue after upgrading to Lion. I had two Developer folders Developer Old and Developer. I used Clean my Mac to remove Dev Old but still had something leftover - i decided to remove dev completely and re-install from MAS. Now I have no xcode installed but MAS shows installed - I still have install Xcode in Applications and Launchpad but I get exacly same error as chaoskcw while trying to install.

Is there any way I can remove whatever is left after previous xcode to have install available in MAS?

+1 on OS X 10.7.1 (11B26), late 2008 macbook. i wanted to install the unix development package with it this time. please resolve asap. (wish Mr Jobs' health is good and improving)

I managed to uninstall xcode completely. I browsed /Library/Developer/4.1/ and found uninstall-devtools asked me for sudo so I run:

sudo /Library/Developer/4.1/uninstall-devtools --mode=all

sudo /Library/Developer/Shared/uninstall-devtools --mode=all - both worked fine

Then I looked at the logs /var/log/system.log and saw something strange:

Aug 28 04:41:28 Hadouken com.apple.kextd[16]: Can't load /System/Library/Extensions/iSpy.kext - no code for running kernel's architecture.

Aug 28 04:41:18 Hadouken com.apple.launchd[1] (com.taoeffect.ispyd): Throttling respawn: Will start in 10 seconds

I don't know what the iSpy is so I went /System/Library/Extensions and removed iSpy.kext and I got:

Aug 28 05:27:51 Hadouken com.apple.launchd[1] (com.taoeffect.ispyd[6406]): posix_spawn("/Library/iSpy/ispyd", ...): No such file or directory

Aug 28 05:27:51 Hadouken com.apple.launchd[1] (com.taoeffect.ispyd[6406]): Exited with code: 1

I navigated to /System/Library/LaunchDeamons and removed com.taoeffect.ispyd.plist

Restart and viola - worked!

I hope this helps and I hope someone would be able to explain what the iSpy was - sounds scary.

EDIT:

Xcode installed and working just fine however I still get:

Aug 28 06:09:34 Hadouken com.apple.launchd[1] (com.taoeffect.ispyd[1762]): posix_spawn("/Library/iSpy/ispyd", ...): No such file or directory

Aug 28 06:09:34 Hadouken com.apple.launchd[1] (com.taoeffect.ispyd[1762]): Exited with code: 1

Aug 28 06:09:34 Hadouken com.apple.launchd[1] (com.taoeffect.ispyd): Throttling respawn: Will start in 10 seconds

And I dont know how to remove it anymore :/

I get same problem but:

• Any iTunes process on system.
• Any helper process on system
• /Library/Developer don't exist

Apreciate help

If you are having trouble installing Xcode try this it worked for me:

1. Open Terminal

2. type 'sudo open'

3. drag the 'Install Xcode' from Applications into the Terminal window

4. press Enter/Return (you may have to enter your password)

5. contiune with the installation.

Hope this helps.

Same problem after tips markpb91.

Just right click on the install xcode app. Then choose show package contents. Follow this path "/Applications/Install Xcode.app/Contents/Resources/Xcode.mpkg" double click and boom 😉

I have also downloaded Xcode installer yesterday to my iMac from App Store and it shows this ( Trying to locate volume at / ):

if I click Show contents package/Contents/Resources and click on Xcode.mpkg i got this error (The installer is damaged - The installer can't open the package. There may be a problem with file ownership permissions):

So if I extract all the files to some folders, click get info, the permissions are all set to Read & Write and I don't know what this is.

Anyone got same problem, what should I do? I don't have iTuenesHelper ON or something.

However, on my MacBook Pro I installed without problems..

Some days ago I have added full permission to whole Macintosch HDD and all subfiles, cuz of problems with some other plugin... Could this cause the problem?

I CANNOT get the xcode app to install, after trying numerous things. So far, I have wasted three hours on what should be a simple upgrade, (Love the informative error message they give)

That worked for me. THANKS!

May I ask...

What is the error appearing on your screen

Cheers.

Thanks work for me too.😉
