Error of "[preflight] Unable to parse at line 2 (near "<?php")." when trying to run remote:drush commands

[alphex]

Expected behavior

Running terminus remote:drush sitename.dev uli should get me a login URL for admin.

Actual behavior

It errors out with [preflight] Unable to parse at line 2 (near "<?php").

Steps to reproduce the behavior

None that I can document. Its just happening.

This is a D8 site in question(updated to 8.5.2), and I'm able to run the same command successfully on another D852 site.

I see this on a site without using terminus, just drush. Maybe not terminus related.

@alphex Just ran into this myself — so far I don’t have any other info besides the fact that my colleague and I had a ton of composer-related issues with our vendor folder. Did you manage to isolate/replicate this?

FWIW I do not have issues with the same site running on a local lando instance — drush executes cleanly

Mark.Pantheon support says it has to do with DRUSH 9, as in, its not supported on Pantheon yet. When you do composer require drush/drush it gives you drush 9. you need to force drush 8. I have not yet, though, received a straight word on if Drush 8 is even useful for Drupal 8.5+ See the compatibility chart here : http://docs.drush.org/en/master/install/ ] duran goodyear] alphex information solutions, llc] w: http://alphex.com // v: 267.225.7439 // e: [email protected] On Wed, May 9, 2018 3:13 PM, Mark Llobrera [email protected] wrote: @alphex Just ran into this myself — so far I don’t have any other info besides the fact that my colleague and I had a ton of composer-related issues with our vendor folder.

@alphex Ah! Ty Duran

@alphex Downgrading to 8.1.16 solved this. I tried:

composer remove drush/drush

but that failed.

I had to manually change my composer.json and run composer update. Not sure that was proper, but it worked after I pushed code to Pantheon.

The status of Drush 8 for Drupal 8.4+ is "happens to work". Depending on what happens in Drupal core, it may or may not be possible for Drush 8 to continue to work e.g with Drupal 8.6+. It is also possible that a contrib module could become incompatible with Drush 8, depending on what APIs it uses.

Work is underway to improve support for Drush 9 on Pantheon. It will probably be a while yet before Drush 9 is fully supported on Pantheon.

Is there an update on this issue? I used drupal-composer/drupal-project to bring up a Drupal 8 site on Pantheon and terminus remote:drush sitename.dev -- uli works correctly. Like @alphex pointed out, Drush 8 is not recommended on newer versions of Drupal 8.

[greg-1-anderson]

A stock drupal-composer/drupal-project does not work on Pantheon. Use https://github.com/pantheon-systems/example-drops-8-composer instead. See https://pantheon.io/docs/guides/build-tools/ and https://pantheon.io/docs/guides/drupal-8-composer-no-ci/

The actual issue is that we are trying to figure out how to get our distribution to run on Pantheon.io, but keep our distribution up to date w/latest dependencies. It seems to run fine with Drush 9, so wondering if Drush 9 is supported yet, and if not if it is being worked on.

[greg-1-anderson]

Drupal 8 is supported on Pantheon; however, combining Drops-8 in a distribution can be tricky. Again, I would use https://github.com/pantheon-systems/example-drops-8-composer as a starting point. I would recommend looking at a couple of examples:

• Lightning v2 on Pantheon example-drops-8-composer#33
• Contenta JSON API profile. example-drops-8-composer#93

Note that these examples are old / out-of-date / not maintained. You'll need to start with the latest example-drops-8-composer template and update per those examples.

Drupal 8.8.0 will make it much easier to make a Drupal 8 site with Pantheon + profile additions, but the needed bits have not all been committed to 8.8.x-dev yet.

If you want to chat about any issues specific to your use-case, hit me up on slack (@greg).

[cnovak]

Sorry @greg-1-anderson , meant to say "Drush 9", I updated my comment. Thanks for the update however on "making Drupal 8 site + profile additions". That is another problem I am facing, but did not mean to take over this issue w/separate discussion.

[greg-1-anderson]

Drush 9 is essentially at a functional level on Pantheon right now. The main things that are outstanding is alias file generation and of course updated documentation. Drupal sites using Drush 9 should pretty much work on the platform at this point.
