Encountering an error while trying to run your React Native app from the terminal on iOS can be frustrating. This guide aims to provide a step-by-step solution to resolve the common issue related to the Xcode Command Line Tools, which is often the root cause of this problem.
Understanding the Problem
When running react-native run-ios, you might see an error message like:
Found Xcode project TestProject.xcodeproj
xcrun: error: unable to find utility "instruments", not a developer tool or in PATH
Command failed: xcrun instruments -s
This error indicates a problem with the Command Line Tools setting in Xcode.
Solution Steps
Follow these steps to resolve the issue:
1. Set the Command Line Tools Location
- Open Xcode.
- Select the Xcode menu, then Preferences.
- Navigate to the Locations tab.
- Select your Xcode version from the dropdown under Command Line Tools.
2. Install or Update Xcode Command Line Tools
Use the command line to ensure your Command Line Tools are correctly installed:
sudo xcode-select -s /Applications/Xcode.app
xcode-select --install
sudo xcodebuild -license accept
These commands will set the path, install the Command Line Tools if necessary, and accept the Xcode license agreement.
3. Update React Native
If you’re using Xcode 13 or later, the instruments command has been removed. Ensure your React Native version is up to date by updating your package.json file.
4. Additional Checks
- If the issue persists, try restarting your computer to ensure all settings are applied.
- Check for pending iOS system updates and complete them as needed.
