Updating to composer 2.2.1 replaced ocaramius package-version to 1.11.99 which causes this : Fatal error: Class PackageVersions\Installer contains 2 abstract methods and must therefore be declared abstract or implement the remaining methods (Composer\Plugin\PluginInterface::deactivate, Composer\Plugin\PluginInterface::uninstall)

[Rituparna007]

Hello

I have upgraded composer version to 2.2.1 and PHP version is 7.3.29. After upgrading I am getting this error

Installing ocramius/package-versions (1.5.1): Extracting archive
For additional security you should declare the allow-plugins config with a list of packages names that are allowed to run code. See https://getcomposer.org/allow-plugins
You have until July 2022 to add the setting. Composer will then switch the default behavior to disallow all plugins.

Can you please guide me how can I solve this issue?

[nicolas-grekas]

can you run the command with --no-plugins and share the output of composer why ocramius/package-versions please?
did you update Symfony deps also?

[Rituparna007]

Output of composer why ocramius/package-versions

composer/package-versions-deprecated 1.11.99.4 replaces ocramius/package-versions (1.11.99)
ocramius/package-versions 2.5.0 replaces composer/package-versions-deprecated (*)

Can you please tell me should I run composer update with --no-plugins?
No I did not update Symfony deps.

[Seldaek]

Running composer update --no-plugins composer/package-versions-deprecated ocramius/package-versions should resolve it I'm hoping. The failure in OP is due to it installing 1.5.1 but that's a very old version I assume it came from your lock file?

[Rituparna007]

Thanks for your response. I have applied the command you mentioned here. That's not working. Same error message is showing.

Can you run the update I mentioned above, then run composer why -t ocramius/package-versions and share the output? Also make sure you commit the updated lock file so your deploy uses latest.

It seems to use 1.5.1 because you use PHP 7.3, and ocramius/package-versions 1.6+ requires PHP 7.4 or more, but that's why composer/package-versions-deprecated should be installed instead as that supports php 7.0+.

Maybe you need to explicitly require it if nothing else does require it. e.g. composer require composer/package-versions-deprecated, but the best would be to identify why ocramius/package-versions is needed and get rid of that IMO.
