Gleam not seeing StringBuilder

[vital pelican]

I have this issue with gleam:

===> Compiling thoas
  Compiling gleam_json
error: Unknown module
  ┌─ ...\gleam\app\build\packages\gleam_json\src\gleam\json.gleam:6:1
  │

  │ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

No module has been found with the name `gleam/string_builder`.

error: Unknown type
    ┌─ ...\gleam\app\build\packages\gleam_json\src\gleam\json.gleam:141:41

    │                                         ^^^^^^^^^^^^^

The type `StringBuilder` is not defined or imported in this module.

Code:

import gleam/erlang/process
import mist
import wisp
import wisp/wisp_mist

pub fn main() {
  wisp.configure_logger()

  let assert Ok(_) =
  wisp_mist.handler(fn(_) { todo }, "secret_key")
  |> mist.new
  |> mist.port(8000)
  |> mist.start_http

  process.sleep_forever()
}

StringBuilder has been removed in newer versions of the standard library. Seems like you need to update your gleam_json dep

[vital pelican]

It should be up to date, I installed gleam today xd

[arctic wing]

The version of the gleam_json dependency has nothing to do with your Gleam version

[vital pelican]

Dosent it pull latest one if i dont specify verision?

[arctic wing]

That depends on your other dependencies

[vital pelican]

oh, i do have gleam_json 1.sth

[arctic wing]

Yeah

What does your gleam.toml look like?

[vital pelican]

It works after updating to gleam_json@2

Thanks

now i need to battle windows again

Hi @arctic wing, sorry for the direct ping but what if I don't have gleam_json in my deps? How can i trace which other dependency is depending on an outdated version of gleam_json?

mmmh ok nvm, i checked the manifest and saw glitch was the only dep on gleam_json 1.*

removed it and it now compiles

[arctic wing]

gleam deps tree --invert gleam_json will show you what depends on it

[dire timber]

neat, thank you!
