My Ionic project was running fine a month ago. Today when I tried ionic serve or ionic build then I get the below error:

My simple question is What CLI version is compatible with Angular version 12.2.13? If you really want to know why I am asking this question you can ready further.

So I followed the advice to upgrade to Angular 13 on the official Angular website, I used the following command: npm @angular/cli@13 update @angular/core@13 @angular/cli@13. This route asked me to upgrade my Node.js to version 16 (latest, current). After upgrading node.js to v16 I retried to upgrade to Angular 13 and during this process the installation failed/stopped due to unsupported dependencies and so on. I Googled most solutions and tried and winded up with a project where all my plugins can't be found and so on. So I reversed the above process by uninstalling node.js v16 to v12, removed npm, node_modules and now I am back at the point where I am getting the below error in the pic.

Here's my dev environment from ionic info:

I had the same error but I was using V 11.2.14

The simple solution is to go to package.json file and change "@angular-devkit/build-angular": "^13.0.2" ( it is inside dependencies )

to your compatible version.

So when I changed it to

"@angular-devkit/build-angular": "~0.1102.3",

it worked

This has my solution npm i @angular-devkit/[email protected] --force npm i @angular/cli@12
