Building binary file failed

On Thu, 14 Jul 2022 15:00:18 +0800

The .zip is zero size. The double-click it and found the folder empty.

What if you remove the file first? I re-read the source, and now I
think that zip is called only once per R CMD INSTALL --build. If the
file doesn't exist in the first place, it can't have invalid structure,
right?

Best regards,
