When I build program. It throw errors cause of c++ version. But I already set config in "binding.gyp". It still throw that error. How to solve this problem !!

binding.gyp "cflags_cc": [ "/std=c++17" ], "msvs_settings": { "VCLinkerTool": { "AdditionalOptions": [ "/std:c++17" ] } },

If one answer solution doesn't work, try another one mentioned. Sometimes ClCompile, sometimes VCCLCompilerTool
