UnexpectedValueException 尝试安装 laravelcollective 时无法解析版本约束

问题描述

我是 laravel 的新手，我正在尝试安装 laravelcollective.我只是关注文档here，我在我的项目目录中使用它:

作曲家需要 "laravelcollective/html":"^5.4.0"

不幸的是，在我按下 ented 后，我立即收到以下错误:

[意外值异常]无法解析版本约束:5.4.0:无效的版本字符串:5.4.0"

我只是不知道如何解决这个问题.我在谷歌上没有找到太多东西，再加上我对 laravel 缺乏经验，这让我陷入了困境.

有人可以帮忙吗?

解决方案

你可以在composer.json中手动添加，然后使用composer update.

只需在 "laravel/framework":"5.4.*", 的行下添加 "laravelcollective/html": "5.4.*",>

像这样:

要求":{"php": ">=7.0.0",fideloper/代理":~3.3"，laravel/框架":5.4.*"，"laravelcollective/html": "5.4.*", <-- 添加这一行laravel/修补匠":~1.0"},

I am new to laravel and I am trying to install laravelcollective. I am just following to documentation here and I am using this from my project directory:

composer require "laravelcollective/html":"^5.4.0"

Unfortunately, immediately after I press ented I get the following error :

I just don't know how to troubleshoot this. I didn't find much on google and this combined with my lack of experience with laravel leaves me stuck.

Can someone help?

解决方案

You can add it manually in composer.json then use composer update.

Just add "laravelcollective/html": "5.4.*", under the row with "laravel/framework":"5.4.*",

Like this :

"require": {
        "php": ">=7.0.0",
        "fideloper/proxy": "~3.3",
        "laravel/framework": "5.4.*",
        "laravelcollective/html": "5.4.*", <-- Add this row
        "laravel/tinker": "~1.0"
    },
