devbox shell fails

[TimoBechtel]

What happened?

Hi there :) I wanted to try devbox on my Mac, but it always fails when running devbox shell.

The path of the project does not contain spaces. I installed devbox using home-manager.

I am new to nix, but this seems similar to an error I've got before, when trying to use flakes in a git repo without staging new files before.

---

More context:

• I have flakes enabled and home-manager installed using flakes.
• Also tried installing it using the install script, but get the same error.
• devenv works

Steps to reproduce

1. create an empty directory
2. run devbox init
3. run devbox shell

Command

shell

devbox.json

{
    "$schema": "https://raw.githubusercontent.com/jetify-com/devbox/0.10.5/.schema/devbox.schema.json",
    "packages": [],
    "shell": {
      "init_hook": [
        "echo 'Welcome to devbox!' > /dev/null"
      ],
      "scripts": {
        "test": [
          "echo \"Error: no test specified\" && exit 1"
        ]
      }
    }
  }

Devbox version
