Pkg.status and DataFrame operations fail in Juno Debugger

Tooling Juno
1

I cannot execute either of the following functions successfully with the Juno debugger.
They run fine outside of the debugger, however.

Function 1

function df_debug1()
    df = DataFrame(A=1:3, B=4:6)
    df1 = hcat(df[!,[:A]], df[!,[:B]])
end

In the debugger from Juno.@enter df_debug1(), I see:

ERROR: MethodError: no method matching getfield(Core, Symbol("#kw##invoke"))(::NamedTuple{(:makeunique, :copycols),Tuple{Bool,Bool}}, ::typeof(invoke), ::typeof(DataFrames.hcat!), ::Type{Tuple{DataFrame,AbstractDataFrame}}, ::DataFrame, ::DataFrame)

Outside of the debugger I see:

3×2 DataFrame
│ Row │ A     │ B     │
│     │ Int64 │ Int64 │
├─────┼───────┼───────┤
│ 1   │ 1     │ 4     │
│ 2   │ 2     │ 5     │
│ 3   │ 3     │ 6     │

Function 2

function df_debug2()
    Pkg.status("DataFrames")
end

In the debugger from Juno.@enter df_debug2(), I see:

ERROR: BoundsError: attempt to access "/home/miles/projects/my_project/Project.toml"

Outside of the debugger I see:

    Status `~/projects/my_project/Project.toml`
  [a93c6f00] + DataFrames v0.19.3

That seems to be a JuliaInterpreter.jl bug. Care to open an issue over there?

Thanks for the tip. Did not consider using the CLI debugger outside of Juno.
