bug: poetry cannot install gojsonnet

[MatteoVoges]

Describe the bug/feature
I can't install gojsonnet using poetry.

To Reproduce
Steps to reproduce the behavior:

1. I made a fresh virtual env and cloned kapitan with its submodule reclass.
2. poetry install --all-extras
3. PoetryException

Expected behavior
Poetry should resolve and install all dependencies including gojsonnet.

Screenshots
If applicable, add screenshots to help explain your problem/idea.

If it's a bug (please complete the following information):

• python --version: 3.10
• pip3 --version: 22.0.2
• poetry --version: 1.3.2
• Are you using pyenv or virtualenv? using venv

Additional context

Note: In this example I already run `poetry install` and after that `poetry install --all-extras`

Hello !

From the error message

    × Building wheel for gojsonnet (pyproject.toml) did not run successfully.
    │ exit code: 1

I'd say you don't have golang installed or in your path, which is required to compile gojsonnet.

You're right, thank you. Somehow I completely missed that.
