I got the same error when using npm@7.13.0 and was able to fix it by either downgrading to npm@7.5.4 or by running npm update --force command.

Try:

npm i --legacy-peer-deps

For more information have a look on:

its something definitely wrong with npm 7.*.* .. i tried npm i --legacy-peer-deps and it worked for me...

however it shouldn't be like this and dependencies should handled in latest stable version..

here is the detailed reasoning of why it may cause:

What does npm install --legacy-peer-deps do exactly? When is it recommended / What's a potential use case?
