I just upgraded XCode to 4.3.1. I'm using a script to build (and then deploy through Testflight) my app. But I now receive this error:
Error: No developer directory found at /Developer. Run /usr/bin/xcode-select to update the developer directory path.
I've no /Developer dir in my machine: how can I fix it?
sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer
You could also do this instead ...
sudo ln -s /Applications/Xcode.app/Contents/Developer /Developer
Everything you guys answered is correct. But for those who hit the following error are missing a step:
Error:
"xcode-select: Error: Path "/Applications/Xcode.app/Contents/Developer" is not a directory."
Missing step:
Double click your xcode 432.dmg. Now don't double click the xcode.app to use it. Instead copy it /Applications folder and then open it from there to install xcode.
Now use terminal command
sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer
Thats it. Your error won't happen again and Filemerge will work now.
This solved for me:
Mostly this error occurs when you have installed a newer version of xcode. And the command line tools are yet to be initialized.
To resolve this: Go under Xcode Preferences > Locations (tab) > And the bottom options is Command Line Tools. Please select the Xcode version for tools.
Example (For Xcode 8.3.3): Go under Xcode Preferences > Locations (tab) > And the bottom options is Command Line Tools. Select Xcode 8.3.3 (7D1014).
