在 laravel 中安装作曲家包，该软件包在 laravel componenet 中具有依赖关系

Question

我正在Laravel项目中安装一个软件包。
该包具有以下依赖项：

"require": {
    "illuminate/database": "^5.6",
    "tightenco/collect": "^5.6"
}

如果我在一个新的作曲家项目中安装该软件包，它可以完美运行。

这是我得到的错误。

Answer 1

您尝试添加的软件包具有当前版本的 laravel 不支持的依赖项，因此您需要升级 laravel 框架版本才能安装该软件包。

只需在 composer.json 文件的必需部分中设置"laravel/framework"："5.6.*"，然后运行 composer 更新。
