Error Running React Native App From Terminal (iOS)

Full error message

I am following the tutorial on the official React Native website.

Using the following to build my project:

react-native run-ios

I get the error:

Found Xcode project TestProject.xcodeproj
xcrun: error: unable to find utility "instruments", not a developer   
tool or in PATH

Command failed: xcrun instruments -s
xcrun: error: unable to find utility "instruments", not a developer 
tool or in PATH

Although, when I run the app from the .xcodeproj, everything works fine.

Any suggestions?

Check out this link (Running react-native run-ios occurs an error?). It appears to be a problem with the location of Command line tools. In Xcode, select Xcode menu, then Preferences, then Locations tab. Select your Xcode version from the dropdown and exit Xcode.
