How should I fix it?
npm@7 has stricter dependency resolution than previous versions. If you can update the version of webpack in your root project, that may resolve it. An alternative easy quick thing to try is npm install --legacy-peer-deps.
I met the same problem.
try to run the command with --force , if you don't use the related package.
e.g.
npm install --verbose --force
Downgrade to a lower npm version with, for example,
npm install npm@6
