Answer 1

在composer.json文件中指定了一个依赖冲突，你说你想要"laravel/passport": "^7.2"或更高版本，但正如你 在喜欢的 composer 文件中看到 的那样，它需要laravel/passport 5.0所以降级您的依赖性要求。

此外，我很确定护照 5.x 与 Laravel 5.6 兼容，因此您也需要将 Laravel 降级到^5.6 。

改变：

"laravel/framework": "5.7.*",

"laravel/passport": "^7.2",

和：

"laravel/framework": "5.6.*",

"laravel/passport": "^5.0",

然后执行composer update

Answer 2

在您的composer.json文件中删除此内容：

"require": {
    "avored/ecommerce": "2.*",
}

然后更新作曲家： composer update

这个包（ avored/ecommerce ）与 Laravel 5.7 不兼容

出于测试目的，我在 Laravel 5.5、5.6 和 5.7 中尝试了此命令（ composer require avored/ecommerce ecommerce ）

它仅适用于Laravel5.5 ，其他 5.6 和 5.7 我也遇到了与您相同的错误。
