Npm install gives warnings, npm audit fix not working

Often times, this is related to package-lock.json messing. I would suggest to try to:

1 - Delete your package-lock.json

2 - Delete your node_modules folder

3 - Try npm install again

This used to fix several issues when adding new packages in my angular apps.

Good luck!

The best thing I recently learn was install the npm-check-updates. It does everything automatically.

run ncu for list in my case was this:

 $ ncu

 babel-core           ^6.26.0  →  ^6.26.3
 babel-loader          ^7.1.5  →   ^8.0.6
 babel-preset-env      ^1.6.1  →   ^1.7.0
 copy-webpack-plugin   ^4.6.0  →   ^5.0.5
 style-loader         ^0.20.2  →   ^1.0.1
 webpack                4.0.0  →   4.41.2

then run ncu -u to upgrade automatically.
