I'm following the first lecture in the plutus pioneer program but I cannot set up the local environment. The error happens when running npm start on a nix-shell after initializing the playground server.

The following purescript packages are needed by the generated code:

  - plutus-playground-client
  - purescript-either
  - purescript-foreign-generic
  - purescript-maybe
  - purescript-ordered-collections
  - purescript-profunctor-lenses
  - web-common

Successfully created your PureScript modules!
plutus-playground-server: user error (Error evaluating simulation: JsonDecodingError {expected = "EvaluationResult", decodingError = "Error in $: not enough input", input = ""})

I'm using windows 10 with WSL2

  • I would recommend opening an issue on the plutus issue tracker for this kind of case: github.com/input-output-hk/plutus/issues

  • Might be this? "If you're using Windows and WSL, make sure the plutus repo clone is located in the WSL filesystem" (stackoverflow.com/questions/68276780/…)

  • No, it is located in the WSL filesystem. I'm planning to switch to ubuntu

I recommend installing Virtual Box and using NixOS or just installing NixOS on a flash drive.

Here is an installation guide.

    Are you running in a Nix shell?
