Bug Report

Problem

Since 25th Nov at about 13:40 GMT, whenever I try to add a platform (ios or android) using cordova platforms add I receive an error and am unable to install the platform.

This issue seems to have been raised for ionic since near the same time yesterday ionic-team/ionic-cli#4615

What is expected to happen?

iOS / Android platform added to project

What does actually happen?

Exception is shown

iOS
Using cordova-fetch for cordova-ios@^6.1.0
Failed to fetch platform cordova-ios@^6.1.0
Probably this is either a connection problem, or platform spec is incorrect.
Check your connection and platform name/version/URL.
CordovaError: TypeError: Cannot assign to read only property 'valueOf' of object

Android
Using cordova-fetch for cordova-android@^9.0.0
Failed to fetch platform cordova-android@^9.0.0
Probably this is either a connection problem, or platform spec is incorrect.
Check your connection and platform name/version/URL.
CordovaError: TypeError: Cannot assign to read only property 'valueOf' of object

Information

Issue started to occur yesterday during build automation in Azure Pipelines, I notices npm versions were different, as it still worked locally, but maybe this was cached, as I updated to the same version locally and it started failing, but when I reverted back, it has been failing ever since.

Command or Code

Issue can be reproduced from new project

cordova create hello com.example.hello HelloWorld
cd hello
cordova platform add ios

Environment, Platform, Device

Tested with multiple macOS
