PHP Fatal error: Trait 'Robo\TaskAccessor' not found

Try running drush radix "SUB THEME".

I got the same issue, upgrade drush fixed.

Similar issue: https://www.drupal.org/project/bootstrap_storybook/issues/3178927

#2 works for me.

Please reopen if this is still an issue. Documentation needs update, also Drush 8 is required, Drush 9/10 is recommended.

Hi, on a fresh drupal 9 installation i get the following error

drush --include="web/themes/contrib/radix" radix:create "test"
PHP Fatal error:  Trait 'Robo\Task\Archive\loadTasks' not found in /Users/user/www/d9/web/themes/contrib/radix/Commands/radix/SubThemeCommands.php on line 27

Can you help ?
Thank you

Fixed: i was able to fix the issue above by adding to the main drupal composer.json file the missing Robo library. I am using drush 10.6, drupal 9.2.7, components 8.x-2.4 and radix 4.x-dev .
My updated composer.json file looks like this (in the bottom of the composer.json file):
//Last lines of composer.json file
"require-dev": {
"consolidation/robo": "^1.0.0",
"drush/drush": "^10.6"
}
}
Do not forget to run "composer update" after adding the missing Robo library.

it is necessary to install composer require "boedah/robo-drush"

I'm still not able to install radix subtheme in a starting Drupal 9.3 installation. Same error for me...
I've installed consolidation/robo and boedah/robo-drush.

drush --include="themes/contrib/radix" radix:create "appstato_radix"

@charly71 you could try this patch.

Ran into this issue on a fresh Drupal 9 instance with drush:10.6.2 and drupal/radix:4.x-dev.

Patch from #12 fixed this issue for me.

Edit: Sorry, I pasted the error twice.

On a fresh Drupal 9.3.3 with drush 11.0.2 im having this issue. The patch fixes the issue, however it throws a new issue.

Im guessing that this is related to dependecy issue, since radix requires consolidation/robo:^1.1.4 || ^2 and drush 11.x uses consolidation/robo:^3

@Endika Melero, consider reporting that in a new issue, perhaps to support Drush 11.

In that case, @Endika Melero has also tested patch #12 works. In order to see this merged, should documentation be updated to state that, for now, Radix supports Drush 9 and 10 only?

Thanks to @Endika, pushed the #12 patch to the dev release, have to look into the Drush 11 issue afterward

Closing this and created a related task: https://www.drupal.org/project/radix/issues/3259559

Anyone willing to tell me how to apply / install the patch?

@mauzilla try the latest dev instance with Drush 10 for now, should be okay

@mauzilla, you may find this article helpful: https://www.mediacurrent.com/blog/composer-patches-dependency-your-proje...

I also had this issue, again.
This time from the groud I've used Drush Version 10.6.1 and performed this:
drush --include="docroot/themes/contrib/radix" radix:create "radix subtheme"

and have got an error like this:
PHP Fatal error: Trait 'Robo\Task\Archive\Tasks' not found in /var/www/html/docroot/themes/contrib/radix/Commands/radix/SubThemeCommands.php on line 24

I've tried a lot of methods to fixed that, unfortunately pacth hadn't work for me, and only one thing helped me - updating consolidation/robo by using next command:
composer require consolidation/robo:^3 -W

and creating a radix subtheme was successfull:

drush --include="docroot/themes/contrib/radix" radix:create "radix subtheme"
 2/2 [============================] 100%

i was able to create a subtheme only with after updating the robo to ^3 as KateKarpenko in
