As discussed in Drupal slack, current work around is to follow instructions from https://github.com/mglaman/drupal-check/wiki/Drupal-9-Readiness and use the phar version, I haven't tried yet, will try and update.

[mglaman]

I blame zaporylie/composer-drupal-optimizations or drush/drush-launcher. The former because drupal/core is a dev dependency. The latter... because it seems likely :)

[nikunjkotecha]

It was zaporylie/composer-drupal-optimizations, after removing it, I was able to install drupal-check

thanks @mglaman @zaporylie

drush/drush 9.6.2 requires symfony/console ^3.4 -> satisfiable by symfony/console[3.4.x-dev].

where as drupal-check require symfony/console v4.2

I am also running into this issue. I need this to run with local project composer and not globally. Using the phar is not really the best practice for this.

There are several dependencies that cause this. drush is mentioned above. behat is another. All of these could be fixed if drupal-check allowed symfony/console 3.4. I recommend changing the composer requirement to:
"symfony/console": "~3.2 || ~3.4 || ~4.0"

(sorry, above comment was from me...was logged into wrong gitlab account)

[mglaman]

This was done, and I think it was released. Can you try upgrading?

[mike-potter]

When I looked here at the composer.json in the "master" branch, it still says:
"symfony/console": "~3.2 || ~4.0",
Should I be looking somewhere else?

[mglaman]

Oh, dur I missed the ~3.4

@mike-potter mind opening a specific issue on that? I have tests running against this.

  test_global_require_with_drush:
    <<: *defaults
    steps:
      - start-project
      - run:
          name: Install Drush globally (which is not recommended by Drush team)
          command: |
            composer global require drush/drush
      - global-require

so I'd like to have better coverage against it
