Composer installation of drupal console missing functions
I'm having the same issue.  Per some other posts, I've tried starting fresh


Deleted drupal/console from composer.json (in docroot)
Deleted composer.lock
Ran composer require drupal/console:~1.0 --prefer-dist --optimize-autoloader
Ran composer update drupal/console --with-dependencies


vendor/drupal/console/bin/drupal shows I've got 1.9.3, but the only generate command I get from list is gsa as shown in sisko's post.  I get the same thing in both Drupal 8.5 and Drupal 8.7.
