Broken dependency tree - [email protected]: core-js@<3 is no longer maintained

[sormiston]

Hey all, just wanted to leave a note here for all future learners.

As of March 2021, npm install breaks down with an exit code after hanging on the following line:

npm WARN deprecated [email protected]: 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3 is no longer maintained and not recommended for usage due to the number of issues.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

Here's how to fix it:

1. start clean --> delete node_modules folder and/or package-lock.json, if you have them.

In command line, run:

2. npm install --package-lock-only
3. npm audit fix --force
4. npm install

Happy testing,
Sean
