I have installed Xcode 5 developer preview 3. Before it i had developer preview 2 and now, sometimes in my terminal I see error, for example when I try to autocomplete some commands by tab:
error: active developer path ("/Applications/Xcode5-DP2.app/Contents/Developer") does not exist, use xcode-select to change
I try to change this directory by executing command:
sudo xcode-select -switch /Applications/Xcode5-DP3.app/Contents/Developer
Now xcode has correct path because command
sudo xcode-select -print-path
shows me result:
/Applications/Xcode5-DP3.app/Contents/Developer
but I still see the same error in terminal, see attached: https://dzwonsemrish7.cloudfront.net/items/120Z1S0b1Q302w3J453U/Screen%20Shot%202013-07-24%20at%2016.34.23.png?v=45e9961b
It happened to me once: xcode-select -print-path did stick to the same value and wasn't changing. It appeared that it was always equal to DEVELOPER_DIR environment variable. According to the manpage of xcode-select:
When DEVELOPER_DIR is set, its value will be used instead of the value last passed to -switch xcode_path
So, unsetting DEVELOPER_DIR makes xcode-select -switch working.
Try changing the path in xcode itself.
If you do a:
man xcode-select
It tells you to use the path as:
xcode-select /Application/Xcode-DP4.app
As I've just switched to DP4 to test. That worked for me. I didn't see it point to any of the .app contents. I guess this was probably changed from previous versions...
If you are running beta release. Path should be look like this.
sudo xcode-select -switch /Applications/Xcode-beta.app/Contents/Developer
I've got this error after I change the name of Xcode app. I changed Xcode app to Xcode8.1.app. Then I run command
sudo xcode-select -switch /Applications/Xcode8.1.app/Contents/Developer
and now everything work as beginning.
Not sure are you in my case and your problem is solved or not. Maybe help another one.
