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?

In Mac: After all, you are getting this issue, there may be a chance of missing the following in System Preferences -> Network -> Ethernet -> Select Advanced -> Proxies
add the following line,
*.local,localhost
You may need to install or set the location of the Xcode Command Line Tools.
If you have Xcode downloaded you can run the following to set the path:
sudo xcode-select -s /Applications/Xcode.app
If the command line tools haven't been installed yet, you may need to run this first:
xcode-select --install
You may need to accept the Xcode license before installing command line tools:
sudo xcodebuild -license accept
Or adjust the Command Line Tools
setting via Xcode (Xcode > Preferences > Locations
):
For those like me who come to this page with this problem after updating Xcode but don't have an issue with the location setting, restarting my computer did the trick.
For any such problem:
.expo
folderapk-cache
and you are done..
Hope it helps?
I had to accept the XCode license after my first install before I could run it. You can run the following to get the license prompt via command line. You have to type agree
and confirm as well.
sudo xcodebuild -license
1) Go to Xcode Preferences
2) Locate the location tab
3) Set the Xcode verdion in Given Command Line Tools
Now, it ll successfully work.
In my case the problem was that Xcode was not installed.
In my case the SDKROOT environment variable was wrong, which referred to an old version of iPhoneOSxx.x.sdk. (Perhaps this would have automatically resolved itself after a reboot?)
You can check by running echo $SDKROOT
and verifying that it's a valid path.
I fixed it by updating in .bash_profile:
export SDKROOT=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS11.2.sdk
For me, it turns out that there was an iOS system update pending asking to restart the computer. Restart and let the update finish solved my problem.
None of these solutions worked for me. These two similar problems offer temporary solutions that worked, it seems the simulator process isn't being shutdown correctly:
Killing Simulator Processes
From https://stackoverflow.com/a/52533391/11279823
Activity monitor
, selected cpu
option and search for sim
, killing all the process shown as result.sudo xcrun simctl erase all
. It will delete all content of all simulators. By content if you logged in somewhere password will be gone, all developer apps installed in that simulator will be gone.Opening Simulator before starting the package
From https://stackoverflow.com/a/55374768/11279823
open -a Simulator; npm start
Hopefully a permanent solution is found.
