Hi Xiaonan,

Your mail doesn't really contain enough information for us to help troubleshoot this, but the end result looks very similar to https://github.com/openenclave/openenclave/issues/2849. Can you ensure that you're running the x64 version of the Build Tools Command prompt?

If you are seeing a different error, can you file an issue with your detailed errors at https://github.com/openenclave/openenclave/issues?

Thanks,
Simon
