Laravel版本：5.8.29
PHP 版本 $ php --version: PHP 7.2.24 (cli)
数据库驱动程序和版本$ mysql --version：mysql Ver 8.0.23-0ubuntu0.20.04.1
Doctrine/Inflector: 1.4

        "doctrine/inflector": "1.4.0"
    },

问题陈述：

以下关系在本地主机上工作但在服务器上抛出错误。这似乎是 Doctrine/Inflector 包的问题。

Note: Its working on Localhost but not on server setup.

$ php artisan tinker
>>> $borrower = Borrower::with('application')->find(2);

PHP Deprecated:  The "Doctrine/Common/Inflector/Inflector::pluralize" method is deprecated and will be dropped in doctrine/inflector 2.0. Please update to the new Inflector API. in /path/vendor/doctrine/inflector/lib/Doctrine/Common/Inflector/Inflector.php on line 264

Answer 1

问题是 doctrine inflector 方法，也许你需要升级它，否则其他解决方案是将你的 Laravel 版本至少升级到 7.x。

尝试在命令行中升级您的软件包版本：

composer update

然后安装新的 doctrine/inflector:

composer require doctrine/inflector
