Windows npm start error

[johnroper100]

I ran npm install, and then npm start, and got this error:

npm start

Hi @johnroper100, it looks like this is an issue with the way our package.json works with Windows. In the meantime does running node_modules\.bin\webpack-dev-server --port 8601 --content-base=build work for you?

[johnroper100]

Yes!

I get these errors in the web browser though:

@johnroper100 Please confirm this is resolved in the most recent version of master. Those console warnings are expected and coming from scratch-blocks, not the gui. The first one is a suggestion I recommend as well, the extension is very useful.
