  2. Node or Prebuilt Installer

code -v

To verify that NPM is installed, type

npm -v

Since October 4, 2021, NPM versions on before version 7, will produce an error stating that TLS 1.2 or higher must be used when installing packages.

Or, you could try upgrading to the latest version of NPM using the command line,

npm install -g npm

or (depending on your existing version of NPM)

npm install --location=global npm

Then test your version is at least version 7 or higher.

npm -v
