Question: When installing `create-react-app`, I get this error when I start the development server (npm start):

```
./src/index.css (./node_modules/css-loader/dist/cjs.js??ref--6-oneOf-3-1!./node_modules/postcss-loader/src??postcss!./src/index.css)
Error: No valid exports main found for 'myproject\node_modules\colorette'

```

I've reinstalled `create-react-app` globally with `create-react-app -g` and tried running it with `npx`, but I still get this error.
Is there anything else I can do?

Answer: 
Node version 13 has an issue for ReactJs, please check your version.
You can update or degrade(LTS version) your node version to work ReactJs properly
This is because latest version of colorette doesn't supported on node Version < 14.
Try below steps if you don't want to install node V14.5

To uninstall colorette:
npm uninstall colorette

To install colorette version 1.2.0:
npm install colorette@1.2.0

This fixed my issue.

Else you can simply upgrade the node version.
