after moving my App to another computer I have trouble with runing npm-install. Here is a content of my package.json:

After running npm-install here goes the Error:

I tried running npm-install --legacy-peer-deps, but the command install Angular Version 14?? Instead of 8 and the app won't even run. Could someone help me understand what is causing the error? Thanks in advance.

Update: Problem Solved. Solved it by manually editing Angular packages to match:

"@angular/compiler-cli": "^8.2.14"

The Angular packages now looks like:

    "@angular/animations": "8.2.14",
    "@angular/common": "8.2.14",
    "@angular/compiler": "8.2.14",
    "@angular/core": "8.2.14",
    "@angular/forms": "8.2.14",
    "@angular/localize": "^9.1.13",
    "@angular/material": "^8.2.3",
    "@angular/platform-browser": "8.2.14",
    "@angular/platform-browser-dynamic": "8.2.14",
    "@angular/platform-server": "8.2.14",
    "@angular/router": "8.2.14",
