ErrorException 未定义的偏移量：0 laravel

Question

in my laravel project the barryvdh debugger was installed, I was trying to make pdf using barryvdh pdf package for that i run the composer command on my dev server which was

composer require barryvdh/laravel-dompdf

之后它显示了 class 的错误，因为我使用了命令

php artisan vendor:publish

之后它显示错误 ErrorException (E_NOTICE) Undefined offset: 0 ErrorException …/vendor/laravel/framework/src/Illuminate/Support/Collection.php1802

它在开发服务器上显示错误。所有 API 工作正常，但 web 视图不起作用。 请帮帮我。 提前致谢。

Answer 1

php artisan vendor:publish

尝试这个：

php artisan vendor:publish --provider="Barryvdh\DomPDF\ServiceProvider"
