You have dependency conflict (incorrect and potentially broken dependency) as it says, So try to run the command with --force, or --legacy-peer-deps.

Solution 2: Use –legacy-peer-deps

Use this command

npm install --save --legacy-peer-deps

Solution 3: npm config set legacy-peer-deps true

In addition to using the --legacy-peer-deps command line option, this can also be set more permanently as a config option:

npm config set legacy-peer-deps true

Solution 4: Try npm cache clean –force

Try removing the node modules and package-lock.json file and run the command npm install or Try npm cache clean --force
