For better integration with the oclif framework, it's more idiomatic to use this.error() to handle this version check failure. This method is designed for reporting errors and exiting in an oclif command, providing consistent error formatting and improving testability by allowing this.error to be mocked. The Error: prefix is not needed as this.error() adds it automatically.
