BSON doesn't seem to work with Pluto.jl and DataFrames.jl

[BoZenKhaa]

The following code

begin
    using BSON
    using DataFrames
    using DrWatson

    b = DataFrame(v = [1,2],l = ["a", "b"])
    DrWatson.save("./test.bson", Dict(:b=>b))

    BSON.load("./test.bson")
end

fails in Pluto notebook with

UndefVarError: DataFrames not defined

This code runs fine in REPL. When using JLD2, there is no problem in loading saved files, which makes me think this may be a BSON issue and not Pluto or DataFrames issue.

This seems to be a duplicate of https://github.com/JuliaIO/BSON.jl/issues/25. Please use BSON.load("./test.bson", @__MODULE__)

[BoZenKhaa]

Thanks a lot for the tip! However, #25 seems to be closed?

[haozhangphd]

Yes it is closed by #91, but the default value of load(x, init=Main) can still cause confusions...

[BoZenKhaa]

Ok, thank you for clarification. I think it could be worthwhile to keep this issue open since the error message seems very cryptic, at least to me. Or should I close this?
