IndexError: list index out of range

[Victor-Lerman]

I have tried:

echo "let mutable a =1" > 1.f#
python3 -m polyenv f# 1.f#

but I got

Traceback (most recent call last):

I am working on mac and using python 3.7.

Hello, @Victor-de-shtab Thank you for raising an issue.

The problem is that the F-Sharp extension is fs, not f#. Also, calling this language on polyenv is achieved by using fs-mono or fs-core (for .NET core).

I just called polyenv fs-mono 1.fs with the following content:

open System

[<EntryPoint>]
let main argv =
    printfn "Hello World from F#!"
    0 // return an integer exit code

And got:

Hello World from F#!

Did that help?
