Your kernel headers for kernel 4.19.6+ cannot be found at/lib/modules/4.19.6+/build

I have same problem here but not always, I have the issue on some raspberry and some other not ! I always first update raspbian to be sure it’s well latest (november 2018) release that is used and sometimes install of Seeed drivers works fine and sometimes fail with that error unless it has installed headers first !!



Someone else ? as not sure what’s the problem exactly !
