Different behavior on Linux vs Darwin

[djacu]

I am trying to create a devShell and am getting different behavior on Linux vs Darwin. Specifically the prepare script is causing issues on Linux. See this commit hash for reference.

In the package.json file there is a line "prepare": "husky install". On Darwin, this executes without issue. On Linux, the following error occurs.

In fact, the Darwin environment can seemingly execute any code. We switched it to "prepare": "astro --version" and it showed up in the build logs. Is the prepare script supposed to work differently on Darwin vs Linux or is there some other more general issue?

For reference, this is the flake file.
