Expected or Desired Behavior

yo @microsoft/sharepoint should be updated to use Gulp 4.

Observed Behavior

Command yo @microsoft/sharepoint with all default settings for SharePoint Online Application Customizer generates project with dev-dependency from gulp 3.9.1.
Gulp 3 is not compatible with NodeJS 12 LTS. It crashes with exception https://github.com/gulpjs/gulp/issues/2324
The single solution is to use Gulp 4 that doesn't depend on outdated packages.

Steps to Reproduce

1. Install NodeJS LTS (it's 12.13.0 currently)
2. run npm install -g yo gulp @microsoft/generator-sharepoint
3. run yo @microsoft/sharepoint with all defaults
4. try to build solution gulp bundle --ship
5. You will receive exception https://github.com/gulpjs/gulp/issues/2324

Thanks for the comment.

Unfortunately, you are using an unsupported version of Node. SPFx currently only supports Node 10x. Please uninstall Node 12, and re-install Node 10.
