Laravel 9 upgrade issue during deployment-CodePudding

I have an existing Laravel 8 application that is deployed in Google cloud App Engine.

I'm trying to upgrade to Laravel 9, however facing a strange issue while trying to deploy -

Updating service [default]...failed.

Script php artisan config:clear handling the post-install-cmd event returned with error code 1

The error occurs while trying to clear either of route, cache or config. This is the relevant section in composer.json that triggers the error -

"scripts": {
        "post-autoload-dump": [
            "Illuminate\\Foundation\\ComposerScripts::postAutoloadDump",
            "@php artisan package:discover --ansi"
        ],     
        "post-root-package-install": [
            "@php -r \"file_exists('.env') || copy('.env.example', '.env');\""
        ],
        "post-create-project-cmd": [
            "@php artisan key:generate --ansi"
        ],
        "post-install-cmd": [
            "chmod -R 755 bootstrap\/cache",
            "php artisan config:clear"
            "php artisan route:clear",
            "php artisan cache:clear"
        ]
    }

I have tried to Google but haven't found any relevant answer yet. I am not quite sure what is causing this issue and kind of exhausted all the avenues I could think of. Any help on this would be greatly appreciated.

I am upgrading from Laravel 8.0 to 9.11 and PHP 7.2 to 8.0.2.

In my app.yaml, runtime of app engine is set to php81.

Some users had similar error because of storage directory structure. I have the following directory structure under storage, however I don't think the error is related to this. My directory structure hasn't changed at all, the only change is the upgrade of Laravel and PHP.

storage
 - framework
   - cache
      - data
   - sessions
   - views

Thanks in advance.

Try setting the runtime to php80: https://github.com/symfony/symfony/issues/42231

CodePudding user response：

Once you installed the new PHP version did you run composer global update so that you upgrade the global composer dependencies?

You can try running composer self-update and then try running global update.
