It should be there, if you have installed Xcode or the command line tools. > :debug:build > SDKROOT='/Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk' Does the directory /Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk exist? Does the file /Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/usr/include/sys/types.h exist? They should. If they don't, reinstall the command line tools. If you have Xcode installed, what version? If you've upgraded to Xcode 11, since you're on Mojave, you may have fewer problems by downgrading to Xcode 10. This is just general advice for Mojave users, and probably does not relate to this problem you're experiencing now.
