Creating new code sharing project in Nativescript gives dependency error on tslint and tslint-rules - nativescript

Question

I'm working on a Nativescript project that needs to be converted into native Android code. I have little Nativescript experience so I'm doing a tutorial on "code sharing".
https://docs.nativescript.org/code-sharing/creating-a-new-project
I've gone through the setup and have all dependencies installed. I can confirm this with tns doctor:
✔ Getting environment information
No issues were detected.
✔ Your ANDROID_HOME environment variable is set and points to correct directory.
✔ Your adb from the Android SDK is correctly installed.
✔ The Android SDK is installed.
✔ A compatible Android SDK for compilation is found.
✔ Javac is installed and is configured properly.
✔ The Java Development Kit (JDK) is installed and is configured properly.
✔ Xcode is installed and is configured properly.
✔ xcodeproj is installed and is configured properly.
✔ CocoaPods are installed.
✔ CocoaPods update is not required.
✔ CocoaPods are configured properly.
✔ Your current CocoaPods version is newer than 1.0.0.
✔ Python installed and configured correctly.
✔ The Python 'six' package is found.
✔ Xcode version 12.4.0 satisfies minimum required version 10.
✔ Getting NativeScript components versions information...
✔ Component nativescript has 7.2.1 version and is up to date.
Then I've run the 2 mentioned commands:
$ npm i -g #nativescript/schematics

run `npm fund` for details
And then the second one, but the issue seems to be already in the first command:

Any help would be greatly appreciated.
This issue seems to be the same. I've also tried --force and --legacy-peer-deps
Downgrading node as suggested in this thread I could try as a last resort but the question does not answer which specific version I should downgrade to then.
