Issue title

The ISSUE-GROUP should be one of:

• console

Problem/Motivation

When running Drupal console i get: [ERROR] Class Drupal\Core\DrupalKernel does not exist. as well as: Drupal Console version 1.9.4 and usage hints as well as command summary; although command summary is not correct list of commands

Details to include:

• Why are we doing this? Above all, a summary should explain why a change is needed, in a few short sentences.

How to reproduce

from drupal root folder: vendor/bin/drupal

Details to include:

• Drupal version: 8.7.10
• Console version: 1.9.4
• Console Launcher version: n/a
• OS: Windows 7

Working version Drupal 8.7.10 install. To start fresh (because composer dependencies preventing me from installing console)

• delete composer.lock

• delete /vendors folder

• only thing in composer.json is require line for drush

• install console: composer require drupal/console:~1.0 --prefer-dist --optimize-autoloader --sort-packages

• drush works

• drupal site works

TEST: vendor\bin\drupal site:status

[ERROR] Class Drupal\Core\DrupalKernel does not exist.

[ERROR] Command "site:status", is not a valid command name.

Solution

??

Install Drupal console per project and either export the project's vendor path to bash or use this path vendor/drupal/console/bin/drupal site:status This has worked for me for 3 sites, all with the same error.
