you need to upgrade your settings.yml file. mine has:

compiler:
[...]
    Visual Studio: &visual_studio
        runtime: [MD, MT, MTd, MDd]
        version: ["8", "9", "10", "11", "12", "14", "15", "16"]
        toolset: [None, v90, v100, v110, v110_xp, v120, v120_xp,
                  v140, v140_xp, v140_clang_c2, LLVM-vs2012, LLVM-vs2012_xp,
                  LLVM-vs2013, LLVM-vs2013_xp, LLVM-vs2014, LLVM-vs2014_xp,
                  LLVM-vs2017, LLVM-vs2017_xp, v141, v141_xp, v141_clang_c2, v142]
        cppstd: [None, 14, 17, 20]
