我尝试在docker下安装laravel 5.5 / postgres应用，但遇到错误：

Carbon 1 is deprecated,see how to migrate to Carbon 2.
https://carbon.nesbot.com/docs/#api-carbon-2
    You can run './vendor/bin/upgrade-carbon' to get help in updating carbon and other frameworks and libraries that depend on it.

要在composer.json文件中修复它，我添加了以下行：

"nesbot/carbon": "2 as 1.24.1"

因此composer.json具有：

        ]

    },"config": {
        "preferred-install": "dist","sort-packages": true,"optimize-autoloader": true
    }
}

运行我的应用程序后，出现错误：

[2019-11-11 08:31:40] local.ERROR: Method addSeconds does not exist. {"exception":"[object] (BadMethodCallException(code: 0): Method addSeconds does not exist. at /var/www/lprods_docker_root/vendor/laravel/framework/src/Illuminate/Support/Traits/Macroable.php:96)
[stacktrace]
#0 /var/www/lprods_docker_root/vendor/laravel/framework/src/Illuminate/Support/InteractsWithTime.php(37): Illuminate\\Support\\Carbon->__call('addSeconds',Array)

我看到在供应商/目录下使用了几次addSeconds。

是版本问题吗？如何解决？

# php artisan --version        
Laravel Framework 5.5.44
