replacing "require" by "include" does not import DataFrames

Hi !

I have a old parallel program that works perfectly with "require" and I can't manage to make it work with "include". The reason I try to do that is that "require" is deprecated.

old program that worked :


main :
require("file.jl")

pmap(function, list_of_dataframes)


file.jl :


using DataFrames

function(df)
  readtable(df)
  some computation
  writetable(df2)
end


new program that never worked :


main :
include("file.jl")

pmap(function, list_of_dataframes)


file.jl :


using DataFrames

@everywhere function(df)
  readtable(df)
  some computation
  writetable(df2)
end



So in summary I replaced "required" by "include" and I had @everywhere in front of the function of the file included. But the problem is that DataFrames is not imported and I can't read any dataframe CapturedException(UndefVarError(:readtable). I tried 
@everywhere using DataFrames
 but it did not solve the problem.


RemoteException(2,CapturedException(UndefVarError(:readtable),Any[(:function,symbol("file.jl"),25,symbol(""),-1,1),(:anonymous,symbol("multi.jl"),923,symbol(""),-1,1),(:run_work_thunk,symbol("multi.jl"),661,symbol(""),-1,1),(:anonymous,symbol("multi.jl"),923,symbol("task.jl"),63,1)]))


thank you for your help !

I found a solution that works partially with warnings :

push!(LOAD_PATH, pwd())
using file


WARNING: requiring "file" in module "Main" did not define a corresponding module.
