Case 1: No matching version found for @babel/helper-member-expression-to-functions

After upgrading Angular version from v-10 to V-11, I tried to install the packages, but it didn´t work as expected.

Current Behavior
Run npm install
npm ERR! code ETARGET
npm ERR! notarget No matching version found for @babel/helper-member-expression-to-functions
npm ERR! notarget In most cases you or one of your dependencies are requesting
npm ERR! notarget a package version that doesn't exist.

npm ERR! A complete log of this run can be found in:
npm ERR! /Users/darpanrangari/.npm/_logs/2020-04-08T09_41_15_890Z-debug.log

Possible Solution / How I fixed the bug ?

By downgrading the karma-coverage-istanbul-reporter dependency to version 2.0.0 fixed the problem.

Case 2 : `Error: node_modules/@angular/material/radio/radio.d.ts:199:9 – error TS2611: ‘disabled’ is defined as a property in class ‘CanDisableRipple & HasTabIndex & MatRadioButtonBase’, but is overridden here in ‘_MatRadioButtonBase’ as an accessor.

 get disabled(): boolean;

Possible Solution

I've solved this issue via updating angular material
