DataFrames doesn't precompile

Tooling

I did a Pkg.update(), which installed a new version of DataFrames (0.11.6+), but it won’t precompile, giving the following error message:

I often see errors like this when I attempt to update a package which I’ve already imported in the current Julia session. That is:

using Foo
Pkg.update()
using Foo # this throws a precompilation error

The solution in that case is simply to restart Julia and do using Foo again. Does that help in your case?

This looks like JuliaPro? I don’t think it supports package updates…

@robin it didn’t – I already tried and keep getting the same error message.

@david yes, it’s JuliaPro – so I suppose in that case I should simply install JuliaPro anew?
