Answer 1

Open your command prompt / terminal and run the following command:

Windows users

set NODE_OPTIONS=--openssl-legacy-provider

Mac users

export NODE_OPTIONS=--openssl-legacy-provider
            

OR

Downgrade node version

Answer 2

This error is because of NodeJS being v17 or later.

You will need to follow the following steps:

• Uninstall your current NodeJS version
• Install NodeJS v16 (https://nodejs.org/download/release/v16.19.1/)
• Run Angular as usual

If you want to run it with NodeJS > v16 then upgrade your Angular application first to the latest version and install the current NodeJS LTS.
