調用未定義的方法App \\ Console \\ Kernel :: load（）-Laravel 5.4

Question

我將我的應用程序從5.5 to 5.4降級5.5 to 5.4 ，運行php artisan serve時出現此錯誤

調用未定義的方法App \\ Console \\ Kernel :: load（）-Laravel 5.4

查看其他解決方案，我運行composer dump-autoload來解決此問題，但該問題仍然存在。 同樣的錯誤。 我真的不知道這是否是由下面的composer.json文件中的包引起的

我現在該怎么解決？

提前致謝

Answer 1

問題是您不能確保將代碼更新為與Laravel 5.4兼容。

在Laravel 5.5+隨附的Kernel.php樣板中，

$this->load(__DIR__.'/Commands');

在5.5中添加了此命令，以自動檢測app / Console / Commands目錄中的任何命令。

為了使此代碼在5.4中起作用，您需要刪除該行並在同一文件中protected $commands = [ ]數組下手動注冊所有命令。

如果您想嘗試對其進行調整並將其放入自己的庫中，則load的源代碼位於https://github.com/laravel/framework/blob/5.5/src/Illuminate/Foundation/Console/Kernel.php#L196中Kernel.php

Answer 2

運行composer install命令后刪除供應商文件夾和composer.lock文件

Answer 3

轉到your_project / app / Console / Kernel.php並刪除行

$ this-> load（ DIR 。'/ Commands'）;

在commands（）函數中
