Upgrade angular 11 to 17 gave errors

Question

I have:

Angular CLI 17

Node: 18.20.2

Package Manager: npm 10.5.0

I have old project with version: 11

I have open it and run npm i thennpm audit fix --force

here I run ng v and got:

@angular-devkit/architect 0.1801.2

@angular-devkit/build-angular 18.1.2

@angular-devkit/core 18.1.2

@angular-devkit/schematics 18.1.2

@angular/cdk 11.2.13

@angular/cli 18.1.2

@angular/material 11.2.13

@angular/material-moment-adapter 11.2.13

@schematics/angular 18.1.2

rxjs 6.6.7

typescript 4.0.8

zone.js 0.10.3

after that I have tried to upgrade angular version to 17

So I started by run: ng update @angular/core@12 @angular/cli@12

but I got error

× Migration failed: Incompatible peer dependencies found. Peer dependency warnings when installing dependencies means that those dependencies might not work correctly together.
You can use the '--force' option to ignore incompatible peer dependencies and instead address these warnings later.
See "C:\Users\username\AppData\Local\Temp\ng-UXBEuC\angular-errors.log" for further details.

how can solve this and upgrade to 17

Answer 1

Try what the message says - you should update if using --force flag. After installing, you should be able to bump packages and everything should work
