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 !      Fred    May 27   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.
