I've added

 - core/jquery
 - core/drupal

to mymodule.info.yml

(where mymodule is my module name).

How do I ensure Drupal "sees" these new dependencies?

For example, can I clear the cache, drush cr ?

Or is there another drush command to run or something else to do?

When does Drupal read the info.yml file? When module enabled - yes - but what other times?

I would prefer a command to get it to read that file rather than uninstall my module and reenable my module as this could be inconvenient with regard to config/content needing to be re-setup.

Thank you.


I'm working on solving a problem where anonymous users see Uncaught ReferenceError: Drupal is not defined in console, based on a solution that adds the dependencies I mentioned above: Anonymous Users See Uncaught ReferenceError: Drupal is not defined In console.

  • Are missing another space before the two -? There's only one space, right?

  • Do you mean there are too many spaces on the line before or after the - or do you mean there needs to be an empty line between the 2 dependenices, @leymannx? (thank you for taking the time to look, please let me know your thoughts) Commented Oct 21, 2020 at 14:49

    Before each - there seems to be one space too few. There need to be two spaces before each -. Simply look in other modules in core to compare.

  • +1 Thanks - do you know when, apart from enabling the module, Drupal reads the info.yml file (as per my question)? Also - I notice that some dependencies use a colon, as in drupal:file - should I do the same, instead of the slash? Commented Oct 21, 2020 at 15:06

    hook_requirements() has 3 phases : install (called while the module is installed), runtime (called during regular use of the website), update (called while the update.php is being executed). I am not sure but I guess running an update or cron might read the requirements in .info files.

I think you are mixing dependencies to modules with dependency to libraries. Your code adds a PHP module dependency to core/jquery, and I don't know any module of this name.

(When in module.info.yml)
If you want to add a (JS or CSS) library dependency, use the libraries: key and not dependencies:

(When in module.libraries.yml)
Remember that just defining a library does not automatically load it, you still must add it in module.info (or load it dynamically)
