f# interactive (dotnet fsi) throws System.IO.FileNotFoundException: Newtonsoft.Json

[badgh]

I try to run in fsi this basic example:

// script.fsx
#I @"packages\"
#r @"Newtonsoft.Json\lib\netstandard2.0\Newtonsoft.Json.dll"
#r @"Akka.Serialization.Hyperion\lib\netstandard1.6\Akka.Serialization.Hyperion.dll"
#r @"Akka\lib\netstandard1.6\Akka.dll"
#r @"Akka.Streams\lib\netstandard1.6\Akka.Streams.dll"
#r @"Akkling\lib\netstandard1.6\Akkling.dll"
#r @"Akkling.Streams\lib\netstandard1.6\Akkling.Streams.dll"

open Akka
open Akka.Streams
open Akkling
open Akkling.Streams

let system = System.create "streams-sys" <| Configuration.defaultConfig()
let mat = system.Materializer()

then run the script with: dotnet fsi script.fsx

This gives the following error:

> dotnet fsi .\script.fsx

I also tried all other versions of Newtonsoft.Json.

I use the latest F# Interactive, available by running dotnet fsi:
Microsoft (R) F# Interactive version 10.6.0.0 for F# 4.7
All packages were installed with paket for framework: netstandard2.0
dotnet --info: .NET Core SDK Version: 3.0.100 Commit: 04339c3a26
