I tried to set the environment variable export SDKROOT=$(xcrun --sdk macosx --show-sdk-path) but it didn't work.
Running the command xcrun --sdk macosx --show-sdk-path yielded the following result:

`/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX13.0.sdk`
