I ran just gm command with no options and simply answered questions.. this worked. Guessing one of the arguments no longer matches the documentation. Perhaps a better error message would be useful?

[hjuarez20]

Hi @liquidcms The problem is that you are using an absolute path that doesn't exist in the --module-path option. You can use the absolute path if the folder is valid

If you try

drupal generate:module \
--module="Qleva" \
--machine-name="qleva" \
--module-path="modules" \
--description="Custom functions for Qleva mini-site." \
--core="8.x" \
--package="Qleva" \
--module-file \
--no-interaction

Everything will work fine, I will change the examples in the languages repository.

Thank you.

[solody]

I got this error too, even I don't use the absolute module path.
The module files generate successfully except the composer.json file.
What to do :(

bash-4.4# su - application -c "cd /app/web/sites && /usr/local/bin/drupal gm"

 // Welcome to the Drupal module generator

 Enter the new module name:
 > Che Migration

 Enter the module machine name [che_migration]:
 > 

 Enter the module Path [modules/custom]:
 > profiles/custom/che/modules/custom

 Enter module description [My Awesome Module]:
 > Che project's migration functionalities.

 Enter package name [Custom]:
 > Che

 Enter Drupal Core version [8.x]:
 >

I found why my problem, the path profiles/custom/che/modules/custom dosen't exist.
Please make sure that the path inputed had created.

[enzolutions]

@solody thank for your report, could you create a new issue, thanks in advance

[solody]

I'm back again, I found that it's a bug actually.
This time, the path profiles/custom/che/modules/custom is actually exist, and the error still occur.

[MakaziMtingwa]

I encountered this same problem from my Drupal root folder. Changing the module path from module/custom to web/module/custom fixed the problem.

Encountered this again and was able to fix by not specifying dependencies. Didn't need to include 'web' for the module path.

[aleixq]

For me it works if no dependencies are specified.

[Cprofessionals]

For me it works if no dependencies are specified.

this was my work around as well.

[GiorgosK]

For me clearly the problem was trying to create composer.json. Answering no to relevant question allowed for the operation to complete.

[karol-haltenberger]

Actually, the error occures if BOTH composer.json and dependencies are selected.
It happens with the parameters specified and in interactive mode too.

(-n option used to avoid extra questions)

This works, creates a composer file, no dependencies
drupal generate:module -n --module="AAA" --machine-name="aaa" --module-path="modules/custom" --description="AAA" --core="8.x" --package="Custom" --module-file --test --twigtemplate --composer

This also works, adds dependencies, no composer file
drupal generate:module -n --module="BBB" --machine-name="bbb" --module-path="modules/custom" --description="BBB" --core="8.x" --package="Custom" --module-file --test --twigtemplate --dependencies user

This fails and does not create the composer.json file
drupal generate:module -n --module="CCC" --machine-name="ccc" --module-path="modules/custom" --description="CCC" --core="8.x" --package="Custom" --module-file --test --twigtemplate --composer --dependencies user
