After I updated all packages this morning, several packages (e.g., Gadfly, Optim, KernelDensity) refuse to pre-compile, all giving the following error:
LoadError: UndefVarError: @printf not defined
I deleted the
.julia folder, installed the packages afresh, but I’m running into the same problem. Btw,
@printf works fine (after running
using Printf). Does anyone have an idea what happened?
