Got this working by simply creating a file that imports gsap and contains the animation script, then referencing it in the “scripts” property in block.json.

The Composer Project-based and Global installations were giving me the errors I posted in my last reply. However, I was successful with the command on the composer-installer page:

composer require --dev dealerdirect/phpcodesniffer-composer-installer

Following those official instructions, I get either a permissions issue when the script tries to write to composer.json, or it can’t find that file as in the following case:

? composer config allow-plugins.dealerdirect/phpcodesniffer-composer-installer true

In ConfigCommand.php line 218:
                                                                   
  File "./composer.json" cannot be found in the current directory  
                                                                   

I’ve tried creating composer.json before running the command again, as well as changing its permissions and those of the parent directory, but no luck.

I’m on a Mac with an M2 chip.
