What happened?

If I try to install the toga library through pip inside .venv it gives me this error:

(devbox)

installing cairo or pycairo doesn't solve it

Steps to reproduce

Create a devbox with the latest version of python and try to install toga through .venv

Command

add, shell

devbox.json

{
  "packages": [
    "pipx@latest",
    "python@latest",
    "cairo@latest",
    "python312Packages.pycairo@latest"
  ],
  "shell": {
    "init_hook": [
      ". $VENV_DIR/bin/activate"
    ],
    "scripts": {
      "test": [
        "echo \"Error: no test specified\" && exit 1"
      ]
    }
  }
}

Devbox version

0.9.0

Nix version

nix (Nix) 2.18.1

Hi @Heus-Sueh, you're definitely in the right place! It looks like toga requires a few native libraries.

Try removing python312Packages.pycairo (we recommend just using a pip virtual environment) and installing the dev outputs for cairo and gobject-introspection. You'll also need pkg-config so that pip can find the libraries:

dx rm python312Packages.pycairo
dx add pkg-config@latest
dx add cairo@latest -o out,dev
dx add gobject-introspection@latest -o out,dev

That should get you a devbox.json that looks something like:

{
  "packages": {
    "pipx":       "latest",
    "python":     "latest",
    "pkg-config": "latest",
    "cairo": {
      "version": "latest",
      "outputs": ["out", "dev"]
    },
    "gobject-introspection": {
      "version": "latest",
      "outputs": ["out", "dev"]
    }
  },
  "shell": {
    "init_hook": [
      ". $VENV_DIR/bin/activate"
    ]
  }
}

  }
}

Thanks for the help, I'll test this solution later
