Upgrade kylekatarnls/update-helper breaks all extensions

zullin

Hey!

I'm trying fix the error:
Fatal error: Class UpdateHelper\ComposerPlugin contains 2 abstract methods and must therefore be declared abstract or implement the remaining methods (Composer\Plugin\PluginInterface::deactivate, Composer\Plugin\PluginInterface::uninstall) in /var/www/flarum/vendor/kylekatarnls/update-helper/src/UpdateHelper/ComposerPlugin.php on line 11

After completing the steps from the issue all flarum extensions disappear from the admin panel:

I would be grateful for the help!

PHP version: 7.4.12
Composer version: 2.0.13
Flarum version: 0.1.0-beta.12
kylekatarnls/update-helper version: 1.2.0

zullin Flarum version: 0.1.0-beta.12

Where did this error come from? Beta 12 is ancient at this point, is there a reason for using it?

askvortsov, the error described occurs with any composer command. Right now I want to upgrade flarum version, but this error prevents this 😟

For example:

/var/www/flarum # composer list

Fatal error: Class UpdateHelper\ComposerPlugin contains 2 abstract methods and must therefore be declared abstract or implement the remaining methods (Composer\Plugin\PluginInterface::deactivate, Composer\Plugin\PluginInterface::uninstall) in /var/www/flarum/vendor/kylekatarnls/update-helper/src/UpdateHelper/ComposerPlugin.php on line 11

/var/www/flarum # composer help

Fatal error: Class UpdateHelper\ComposerPlugin contains 2 abstract methods and must therefore be declared abstract or implement the remaining methods (Composer\Plugin\PluginInterface::deactivate, Composer\Plugin\PluginInterface::uninstall) in /var/www/flarum/vendor/kylekatarnls/update-helper/src/UpdateHelper/ComposerPlugin.php on line 11
