Netlify dev with netlify cms gatsby starter fails

I’m trying to set up local development for the Netlify CMS Gatsby starter. I followed the steps here: and was able to get the site setup in Netlify, can access the admin, etc.

Then, following along here: on Win10, I used ‘netlify init’, linked it to github, no issues there.

First time running ‘netlify dev’ it failed and said I needed to run ‘npm install’, so I did that, now ‘netlify dev’ is mostly working, it opens a browser window at ‘localhost:8888’ but it’s blank, and the output has a few errors:

◈ Netlify Dev ◈
◈ Injected netlify.toml file env var: NODE_VERSION
◈ Injected netlify.toml file env var: YARN_VERSION
◈ Injected netlify.toml file env var: YARN_FLAGS
◈ Functions server is listening on 60256
◈ Starting Netlify Dev with gatsby

Update: I found an issue on the github page for the netlify cms gatsby starter, and one of the posts had a suggestion about the sass plugin that fixed the problem:
