Terminus does not install on a drupal-composer/drupal-project project

[mherchel]

Expected behavior

I expect to be able to install Terminus on a drupal-composer/drupal-project project

Actual behavior

When installing drupal-composer/drupal-project project and then Terminus, I receive the following error:

  my_site_name_dir curl -O  https://raw.githubusercontent.com/pantheon-systems/terminus-installer/master/builds/installer.phar && php installer.phar install

Installation failed, reverting ./composer.json to its original content.

Steps to reproduce the behavior

Running MacOS Mojave

# Create and cd into an empty directory
composer create-project drupal-composer/drupal-project:8.x-dev my_site_name_dir --no-interaction
curl -O  https://raw.githubusercontent.com/pantheon-systems/terminus-installer/master/builds/installer.phar && php installer.phar install

[greg-1-anderson]

Terminus is not designed to be installed as part of a Drupal site. Please install it standalone; the .phar is preferred.

@greg-1-anderson I'm pretty sure it is with Lando Might be a different issue but I have a loop drupal/upgrade_status requires nikic/php-parser:^4 pantheon-systems/terminus requres psy/psysh:^0.8 psy/psysh 0.8.18 requres nikic/php-parser:^3

Therefore I have 2 options. No install upgrade_status module which tells me how to get ready for Drupal 9 OR Uninstall terminus from lando and lose all of the terminus integration

[greg-1-anderson]

If the Lando Terminus integration installs Terminus as part of the Drupal project, that's a Lando configuration bug.

[reynoldsalec]

Note that Lando does not install Terminus as part of the Drupal project; you an see in the Dockerfiles for the Pantheon integration how Lando installs Terminus: https://github.com/lando/pantheon/blob/a21b5aaee731afa07ea7005deca10fdcb289d49c/recipes/pantheon/7.3-fpm/Dockerfile

[iStryker]

Thanks for the quick response by the both of you. That is very helpful @reynoldsalec. Currently using the Drupal8/9 recipes not pantheons. Side-note: I feel like lando/lando documentions of https://docs.lando.dev/config/pantheon.html should be updated as I had no clue how pantheon recipe was being built. Should be link/comment inserted to lando/pantheon git repo. And taking it one set further Acquia/Platform.sh etc docs should be updated as well.

[reynoldsalec]

Good point @iStryker; we haven't actually started deploying lando/pantheon to people, but that will start in the next release...as you can see all issues/development is now happening in the integration repos, not lando/lando.
