any help appreciated!

Objective & Problem

• Objective: Use F# as scripting language on Linux, while resolving and installing automatically the package dependencies
• Problem: The #r loading of Nuget package assemblies via Paket doesn't work

In that simplified example, I will use Fake to run a system command:

#r "paket:
nuget Fake.Core"

open Fake.Core

printfn "Test OK"

When I run the script, I got the following error:

$ dotnet fsi test.fsx

/home/mat/fsx-test/test.fsx(1,1): error FS3216: Package manager key 'paket' was not registered in [/usr/share/dotnet/sdk/3.1.403/FSharp; /usr/share/dotnet/sdk/3.1.403/FSharp/], []. Currently registered: nuget

/home/mat/fsx-test/test.fsx(1,1): error FS3217: Processing of a script fragment has stopped because an exception has been raised
