Sounds like an issue with windows trying to build the native sources with node-gyp.

Have you installed windows-build-tools or the windows required sdk packages?

[henbenla]

@makepanic I mess up npm & cnpm, but I install sharp successfully now.

@henbenla @makepanic just got the same issue. What do you mean about npm & cnpm?
Thanks
