Answer 1

you need to delete package-lock.json or yarn.lock then clear npm caches, you can do this by implementing those commands
rm -rf node_modules
rm package-lock.json yarn.lock
npm cache clear --force
npm install

Answer 2

I encountered this most of the time when I pull a new project.
try doing this.
npm install
npm audit fix
then run it again sometimes the cause of this is missing packages .
