“Incompatible peer dependencies” error when updating from Angular v7.2 to v8

Question

I'm usually good about updating my project when a new version of Angular comes out and don't recall ever having any issues, but when trying to update from Angular v7.2.15 to v8.0.1 with ng update @angular/cli @angular/core , I get the following peer dependency errors:

I ran ng update and tried to update each package it listed individually. All of them gave me similar errors. I'm on Node v10.16.0 and NPM v6.9.0

Is there a simple way to fix this?

Answer 1

The issue isn't with the Angular packages, the issue is with the codelyzer package to a minimum version 5.0.0 which includes support for Angular v8.

Once you've updated that package, the ng update command you're using should work as you expect.
