在运行php artisan护照时调用成员函数getDateFormat（）null：install(Call to a member function getDateFormat() on null

在运行php artisan护照时调用成员函数getDateFormat（）null：install(Call to a member function getDateFormat() on null when running php artisan passport:install)

我收到此错误消息：

PHP Fatal error: Call to a member function getDateFormat() on null in /usr/local/ampps/www/project/vendor/laravel/framework/src/Illuminate/Database/Eloquent/Model.php on line 2992

当我试图运行这个命令时：

php artisan passport:install

我正在使用全新安装的laravel v5.3.16以及mysql和mongodb数据库结构。

任何想法如何解决这个问题？

I'm getting this error message :

PHP Fatal error: Call to a member function getDateFormat() on null in /usr/local/ampps/www/project/vendor/laravel/framework/src/Illuminate/Database/Eloquent/Model.php on line 2992

when I'm trying to run this command :

php artisan passport:install

I'm using a fresh installed laravel v5.3.16 with mysql and mongodb database structure.

any idea how to fix this ?

最满意答案

我找到了解决方案，我必须安装laravel然后护照包然后修改mongodb迁移以使其工作。

这是这个行为的顺序造成了这个错误。

I've Found the solution, I had to install laravel and then passport package then modify mongodb migrations to make it work.

It was order of this action which made this error.
