[ERROR:vcvarsall.bat] Invalid argument found : -vcvars_ver=14.16
[ERROR:~nx0] Error in script usage. The correct usage is:
Syntax:
    vcvarsall.bat [arch]
  or
    vcvarsall.bat [arch] [version]
  or
    vcvarsall.bat [arch] [platform_type] [version]
where :
    [arch]: x86 | amd64 | x86_amd64 | x86_arm | x86_arm64 | amd64_x86 | amd64_arm | amd64_arm64
    [platform_type]: {empty} | store | uwp
    [version] : full Windows 10 SDK number (e.g. 10.0.10240.0) or "8.1" to use the Windows 8.1 SDK.

The store parameter sets environment variables to support Universal Windows Platform application
development and is an alias for 'uwp'.

For example:
    vcvarsall.bat x86_amd64
    vcvarsall.bat x86_amd64 10.0.10240.0
    vcvarsall.bat x86_arm uwp 10.0.10240.0
    vcvarsall.bat x86_arm onecore 10.0.10240.0
    vcvarsall.bat x64 8.1
    vcvarsall.bat x64 store 8.1

Please make sure either Visual Studio or C++ Build SKU is installed.
