Hey guys I have a problem. I'm trying to open a project made in Angular 5.2.0 and its Angular/cli version is 1.7.4, my Angular/cli version is 14.0.7... I executed "npm install" and it doesn't give me any error, but when I write "ng version" to see the local version of angular, it gave me an error "Cannot read properties of undefined (reading 'write')", I tried to execute "ng serve --open" and doesn't work neither.
The steps I followed and their results were: 1.- npm install --> ok; 2.- ng version (to check if the Angular's package local version was installed) --> Error = "Cannot read properties of undefined (reading 'write')"; 3.- ng serve --open (to try open the app) --> Error = same as above.

Reset to default 5This error message is not helpful at all. It turns out it may be a wrong angular version.
Try downgrading to version 14.0.0.
npm -g i @angular/[email protected]
In my case, I discovered downgrading to any version 14 or below seemed to work, but that may not always be the case.
Please recreate incrementally with Angular v14.
