Answer 1

I had the same problem.

I removed both node_modules and package-lock.json and then did:

npm install 

And it worked.

Edit by @OwlyMoly Due to new updates and the restriction to old dependencies in package-lock.json is causing this conflicts. By doing npm install won't fix this issue. Instead by ditching npm_modules and package-lock.json and doing npm install will load a new node_modules and that supposed to be required by package.json. You have to commit the new package-lock.json along with your latest changes of the project.
