Thanks this solved my problem! I had installing xgboost which gave me the following error: FATAL:/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../libexec/as/x86_64/as: I don't understand 'm' flag!
I noticed something was wrong with the assembler since running $as --version also gave me a similar error. Replacing /usr/bin/as with the above solved the problem.
