Error: Cannot find module 'sander' when running 'degit'

[heardy]

I followed the getting started guide (https://sapper.svelte.technology/guide#getting-started) but running degit returns an error.

After running npm install -g degit as per the above guide, I ran degit sveltejs/sapper-template my-app and get the following error.

kevin.heard ~/git $ degit sveltejs/sapper-template my-app
module.js:549
    throw err;
    ^

I noticed that sander is in devDependencies, which it looks like it should be in dependencies?

whoops! this was broken in 2.1, but it went undetected because sander was listed as a dev dependency already. Fixed in 2.1.3! thanks
