Fails to install to a path with spaces

[koterpillar]

When the package is added to a project that has spaces in the path, it fails to install:

$ yarn add cloudflared
yarn add v1.22.22

I have traced it to the line:

const sub = spawn(bin, args, { shell: true, stdio: "inherit" });

Is there a reason shell: true is needed there? Works fine without it in my tests.
