THEOS cannot be compiled after the project is created

Sometimes you cannot make a project created with THEOS, and the following error is reported:
/Users/XXX/xxproject/THEOS/makefiles/targets/Darwin/iPhone. mk: 12: *** first argument to 'word' function must be greater than 0. Stop.

Solution: Go back to the following directory, and then
Run the following command: sudo xcode-select-switch/applications/xcode. APP/contents/developer/

Then execute make to complete the compilation.
