Php 编写器需要LarvelCollective html'；不下载依赖性

请协助

我是laravel的新手，无法下载laravelcollective/html的依赖项。。。我使用的是laravel 5.5.13

我需要laravelcollective/html

然而，我面临以下问题

运行时：

composer需要“laravelcollective/html:5.2.*”

（与运行composer update时类似）：

---

我决定使用AngularJS作为前端

---

请注意，此解决方案可能不适用于所有人，使用此解决方案，由于需要其他编写器要求，将来可能会出现问题，例如我需要的身份验证依赖项。

尝试运行

composer Required laravelcollective/html

，它将为您安装最新版本的laravelcollective软件包。

那么您需要哪个版本的

5.2.

或

~5.3.@dev

？你不能同时拥有两者。这是作曲家的一个基本限制。。。如果您需要5.3，那么尝试安装

“laravelcollective/html:5.2.*”

对我来说毫无意义。无论如何，您已经在

composer.json

中安装了v5.3，所以只需

composer安装它即可。我刚刚添加了一个图像，描述了运行composer安装时得到的结果。。。（在帖子**的第一行）**它说已成功生成包清单，但我无法在供应商文件夹中看到已安装的laravelcollective…如果您使用的是Laravel5.5，则此包也应使用版本5.5。。。。

  Problem 1
    - The requested package laravelcollective/html could not be found in any version, there may be a typo in the package name.

Potential causes:
 - A typo in the package name
 - The package is not available in a stable-enough version according to your minimum-stability setting
   see <https://getcomposer.org/doc/04-schema.md#minimum-stability> for more details.

Read <https://getcomposer.org/doc/articles/troubleshooting.md> for further common problems.

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