react-app-rewired npm install not working with node v15

[stedda]

Hi guys, trying to install

"react-app-rewire-antd-theme": "^1.1.4",
"react-app-rewire-less": "^2.1.3",
"react-app-rewired": "^2.1.6",

with node -v 15.12. On npm install this error shows up:

npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR! 
npm ERR! While resolving: adhoc-web@0.1.1
npm ERR! Found: react-app-rewired@2.1.8

npm ERR! 
npm ERR! Fix the upstream dependency conflict, or retry

Mentioning that with node v14 it works just fine.

Thanks

I believe react-app-rewire-less was written for webpack 2/3, and hadn't been upgraded to webpack 4+. Hence it needs the version 1 generation of react-app-rewired. If you're working on a modern CRA project, you'll need version 2 with webpack 4+ rewires.

Try using addLessLoader from customize-cra for adding less instead.
