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

### Function 1

```julia-auto
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:

```julia-auto
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:

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

```

### Function 2

```julia-auto
function df_debug2()
    Pkg.status("DataFrames")
end

```

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

```julia-auto
ERROR: BoundsError: attempt to access "/home/miles/projects/my_project/Project.toml"

```

Outside of the debugger I see:

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

```

That seems to be a [JuliaInterpreter.jl](https://github.com/JuliaDebug/JuliaInterpreter.jl) bug. Care to open an issue over there?

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