My system is:
OS-X 10.14.1 Mojave
To determine the xcode version I ran pkgutil --pkg-info=com.apple.pkg.CLTools_Executables
giving the output:

It appears that my xcode version is 10.1.
Also when I run brew doctor
I see this output:

Warning: Anaconda is known to frequently break Homebrew builds, including Vim and
MacVim, due to bundling many duplicates of system and Homebrew-available
tools.
If you encounter a build failure please temporarily remove Anaconda
from your $PATH and attempt the build again prior to reporting the
failure to us. Thanks!
