If you DON'T install a log service, the errors are actually printed to the console.
If you DO have a log service then just use the command “log <level>” to list the most recent log entries at that level or above. For example “log warn” will give all the warnings and errors but not info or debug. This has a small advantage over printing to the console because you can show the entries at any time rather than scrolling back to when they happened.
