Crash in module installer if a dependency is missing

Not able to reproduce the issue, Please provide more details.

Here is the full error message I'm getting:

OK, but 12k sites use the module and it works for the others. So we do need more details as asked in #2.

What info do you need?

OK I looked carefully at your debug trance and I can reproduce it.

You are missing one of the dependencies of this module. The instructions are here https://www.drupal.org/docs/contributed-modules/drupal-symfony-mailer/ge... → .

This module has a bug in the case of missing dependencies. Although it works fine on the status report, it doesn't work in the module installer. The code in drupal_check_module() uses the returned requirement data is a somewhat strange way.

Thanks I got it working

I encountered the same problem when enabling Drupal Symfony Mailer.

AdamPS & fabricet, could you please share what dependencies are needed? I couldn't find any from the link in #7.

Here are my trace information:

I run into same issue, but I downloaded symfony libraries with ludwig, then I could activate/install the module.

I wonder why is it so hard to document it... :-))

The required dependencies are:

composer require html2text/html2text
composer require symfony/mailer
composer require tijsverkoyen/css-to-inline-styles

It's there in the .install file but not every Drupal admin is a programmer and would to know where to look.
