Cause
ERESOLVE issues with npm@7 are common, because npm7.x is stricter about some things than npm6.x. Usually, the easiest fix is ​​to pass the --legacy-peer-deps flag to npm (eg, npm i --legacy-peer-deps ), or use npm@6.

If this doesn't work right away, maybe remove node_modules and package-lock.json first. They will be recreated.

Solution
Downgrade npm to version 6

or

Use npx to specify the version of npm

npx -p npm@6 npm i --legacy-peer-deps
