npm WARN deprecated core-js@2.6.11

Question

When I enter $ npm install --save react react-dom next, I got this warning:

npm WARN deprecated core-js@2.6.11: core-js@<3 is no longer maintained and not recommended for usage due to the number of issues. Please, upgrade your dependencies to the actual version of core-js@3.

I tried updating it with $ npm install --save core-js@^3, but it shows the same error.

How can I update core?

Answer 1

npm uninstall core-js then npm i core-js should work.
