In summary: I cannot uninstall pdf_reader sucessfully without bringing down my site with this error:
Drupal\Core\Extension\InfoParserException: The 'core' or the 'core_version_requirement' key must be present in modules/contrib/pdf_reader/pdf_reader.info.yml in Drupal\Core\Extension\InfoParserDynamic->parse() (line 73 of core/lib/Drupal/Core/Extension/InfoParserDynamic.php).
( I did search the above error but cannot see anything related).
Have a Drupal 8.9.8 dev site using Composer 1.10.7 (I did try and update to composer 2 but that caused a lot of other errors, which I wanted to save for another day!)
I had pdf_reader installed and wanted to uninstall it.
Used composer to uninstall it:
drush pmu pdf_reader
This completes to success.
I then rebuild the cache with:
drush cache-rebuild
However I noticed in composer.json, there is still an entry:
"drupal/pdf_reader": "1.x-dev",
if I login to drupal and check the installed modules pages I can see it and it's unticked.
At this point if I try and reinstall it using the UI I get the message: PDF Reader is already installed.
If I look in the following directory, I can see the pdf_reader folder still exists /web/modules/contrib/
If I now delete the above folder and clear the cache, it stops the website running with:
The website encountered an unexpected error. Please try again later.
Drupal\Core\Extension\InfoParserException: The 'core' or the 'core_version_requirement' key must be present in modules/contrib/pdf_reader/pdf_reader.info.yml in Drupal\Core\Extension\InfoParserDynamic->parse() (line 73 of core/lib/Drupal/Core/Extension/InfoParserDynamic.php).
At this point if I run:
drush cache-rebuild
I get a similar error:
In ExtensionDiscovery.php line 446:
SplFileInfo::openFile(/var/www/html/web/modules/contrib/pdf_reader/pdf_read
er.info.yml): failed to open stream: No such file or directory
(if I restore the pdf_reader folder and clear the cache the sites come back online).
So it seems like something is out of synch and/or not updating, any help appreciated (I'm far from a drupal expert, so I'm sure it's something simple for an expert))
