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: 
you need to upgrade node version to 14.5 or latest version with:

```
sudo n latest // on mac or linux for latest version

```

for windows just reinstall you node with latest version
Fixed this problem by upgrading node.js to v14.5.0. After upgrading, I also had to delete my node\_modules folder and rerun `npm install`.
