php - 无法使用 Laravel 6.9 安装依赖项

Question

我正在尝试从 https://github.com/barryvdh/laravel-debugbar 安装 barryvdh/laravel-debugbar通过这样做:

composer require barryvdh/laravel-debugbar --dev

我收到这些错误:

c:\wamp64\www\blog>php artisan --version
Laravel Framework 6.9.0

c:\wamp64\www\blog>composer require barryvdh/laravel-debugbar --dev
Using version ^3.2 for barryvdh/laravel-debugbar
./composer.json has been updated

Installation failed, reverting ./composer.json to its original content.

如何解决这个错误？

Answer 1

从您的 composer.json 文件中删除 way/generators 并运行 composer update

"require-dev": {
    .....
    "way/generators": "~2.0"", // <-- remove this line
}

way/generators 适用于 Laravel 4.2 及以下版本，并且您正在使用 Laravel ^6.9
