Part 1

Hi I am trying to build the latest lesson in this set (lesson-32).

I get the following error

$ npm run build

> dojo-blog@0.1.0 build
> react-scripts build

node:internal/modules/cjs/loader:488
      throw e;
      ^

Part 2

I would like to get this blog working as a server-side rendered app as per the following tutorial (which takes a create-react-app style app and delegates the JavaScript UI rendering to a server). The reason I chose this repository is because it follows the create-react-app closely in terms of convention and layout etc. and therefore is possibly the best app to test converting a React app to SSR

I managed to resolve this error by tidying up my Ubuntu environment.

npm install --save react react-dom react-scripts
npm install -g npm@latest
rm -rf node_modules/
npm install
npm run build

The build is now successful

> dojo-blog@0.1.0 build
> react-scripts build
