you'll need to do a few things to npm link this:
bump react and react-dom in filecoin-web-wallet to 16.13.1
bump styled-components to 5.2.0
npm link the components repo
cd into <components repo>/node_modules
rm -rf react react-dom
ln -s ../filecoin-web-wallet/node_modules/react
ln -s ../filecoin-web-wallet/node_modules/react-dom
cd .. (out of node_modules)
yarn build (build the components)
cd ../filecoin-web-wallet
npm run dev
