generate:module gives Fatal error: Call to a member function getPath()

[liquidcms]

[ ISSUE-GROUP ] Short description

The ISSUE-GROUP should be one of: generate:module

Problem/Motivation

Just set up console and tried to run gm command.

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

gives: Fatal error: Call to a member function getPath() on null in E:\www\drupal8a\vendor\drupal\console\src\Generator\ComposerGenerator.php on line 46

Details to include:

• Why are we doing this? Above all, a summary should explain why a change is needed, in a few short sentences.

How to reproduce

Include steps related how to reproduce.

Details to include:

• Drupal version (you can obtain this by running drupal site:status). 8.7.3
• Console version (you can obtain this by running composer show | grep drupal/console). 1.9.1
• Console Launcher version (you can obtain this by running outside of a drupal site drupal --version). 1.9.1
• Steps to reproduce 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

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:

 Enter the module machine name [che_migration]:

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

Composer 1.9.3 PHP 7.2.28

[johnbburg]

I am also running into this. Here is ComposerGenerator::generate():

public function generate(array $parameters)
    {
        $machineName = $parameters['machine_name'];
        $this->renderFile(
          'module/composer.json.twig',
          $this->extensionManager->getModule($machineName)
            ->getPath() . '/composer.json',
          $parameters
        );
    }

$machineName Is the value of the --machine-name= parameter I presume, and this $this->extensionManager->getModule($machineName) is returning a null value because the module you are creating doesn't exist in the list of modules at the time it is called.

I don't have any answers, I just ran into this and attempted to trace it down.

Also confirmed that this appears to work when not using the dependencies option.

[johnbburg]

I just created a pull request to try to address this. The PR doesn't really fix the issue, but it provides some more helpful information. Running the generator will appear as this on error instead of the stack trace you see now:

 [ERROR] Unable to load module: "my_module" from extension manager. This may be an unresolved issue in the
         module generator. This will prevent the generator from creating the composer.json file. Try calling the command
         without setting dependencies. See https://github.com/hechoendrupal/drupal-console/issues/4118

[liquidcms]

Isn't it funny when you google an issue and first result in Google is the post you made a year ago.

anyway, still getting this error a year later. Looking through comments above i was able to get it working by removing --composer and then also answering no when it asked if i wanted to include dependencies.

Also, when using module_path as "/modules/custom", i thought it was odd that it was trying to create the module in D:\Git\Git\modules\custom when i ran the command from the docroot of my site: E:/web/drupal8/web. When i specified absolute path it put the new module in the correct location (E:/www/drupal8/web/modules/custom).

Hi, I was working with Drupal Console and when I was using the drupal gm command (generate module) I got this error message:

// generate:composer
Error: Call to a member function getPath() on null in /var/www/html/vendor/drupal/console/src/Generator/ComposerGenerator.php on line 46 #0 /var/www/html/vendor/drupal/console/src/Command/Generate/ComposerCommand.php(410): Drupal\Console\Generator\ComposerGenerator->generate(Array)

Hey guys,

As @johnbburg mentioned the composer.json is generated through through ComposerGenerator::generate(). But the function $this->extensionManager->getModule($machineName)->getPath() . '/composer.json' is responsible for setting the path.

So you can only generate a composer.json IF you generated the module in the modules folder of your drupal root where it is discoverable for Drupal.

This logic is faulty because (I think most) developers generate their modules outside of the webroot so they can require their module through composer itself. This is the correct procedure to keep dependency management intact.

My proposal is to add the --module-path option that is defined in: https://github.com/hechoendrupal/drupal-console/blob/e582d885aadcf57694043dc8b02acd151f8fdf98/src/Command/Generate/ModuleCommand.php#L122-L127

As an optional option to: https://github.com/hechoendrupal/drupal-console/blob/master/src/Command/Generate/ComposerCommand.php#L61

And if this option is set use that path, instead of the (empty) path provided by the extensionManager.

So for now, if you want to generate modules with a composer.json it's best to generate it in the default location modules/custom so Drupal can provide the path in which to generate the composer.json. After that you can just move the module to where you prefer it.

I'll see if I can provide a patch for you guys in the coming days.

[seanr]

I have not tried that PR, but this fails even when in modules/custom:

drupal generate:module --module="Yeego Connect: Color" \
--machine-name="yeegoconnect_color" \
--module-path="modules/custom" \
--description="Color API enhancements for Yeego." \
--core="9.x" \
--package="Yeego Connect" \
--module-file \
--composer \
--test

It's worth noting that it did generate all of the expected files except for composer.json. It is thus slightly different than (I think) described by @verbruggenalex but that solution may well resolve it. I'm not in an ideal position to test that at the moment so this is purely informational. :)
