It sounds like you are using Visual Studio's Web Compiler extension. There is an open issue for this found here: https://github.com/madskristensen/WebCompiler/issues/413

There is a workaround posted in that issue:

1. Close Visual Studio
2. Head to C:\Users\USERNAME\AppData\Local\Temp\WebCompilerX.X.X (X is the version of WebCompiler)
3. Delete following folders from node_modules folder: caniuse-lite and browserslist Open up CMD (inside C:\Users\USERNAME\AppData\Local\Temp\WebCompilerX.X.X) and run: npm i caniuse-lite browserslist

For Angular Developers

Although, I'm answering this very late. I have a bad habit of checking changelogs of every library I use and while checking the release notes of Angular CLI, I figured out that they released a new patch yesterday (9th Jan 2020) which fixes this issue.

https://github.com/angular/angular-cli/releases/tag/v8.3.22

So when you will run ng update, you should get updates for @angular/cli:

And running ng update @angular/cli will fix this warning.

Cheers!
