无法安装 barryvdh/laravel-dompdf

Question

我无法使用 composer require barryvdh/laravel-dompdf 安装 barryvdh/laravel-dompdf。

我得到的错误是：

[Invalid argument exception] Could not find a matching version of barryvdh/laravel-dompdf. Check the package spelling, your version constraint and that the package is available in a stability which matches your minimum-stability (dev).

所以为了修复这个错误，我在composer.json中包含了barryvdh/laravel-dompdf: master@dev并且做了一个composer update。这次它给了我错误：

The requested package barryvdh/laravel-dompdf could not be found in any version. there may be a typo in the package name

下面是我的composer.json:

{
    "name": "laravel/laravel",
    "description": "The Laravel Framework.",
    "keywords": ["framework", "laravel"],
    "license": "MIT",
    "type": "project",

        "post-root-package-install": [

        ],
        "post-create-project-cmd": [
            "@php artisan key:generate"
        ],
        "post-autoload-dump": [
            "Illuminate\Foundation\ComposerScripts::postAutoloadDump",
            "@php artisan package:discover"
        ]
    },

        "sort-packages": true,
        "optimize-autoloader": true
    },
    "minimum-stability": "dev",
    "prefer-stable": true
}

你认为我在这里遗漏了什么？

Answer 1

使用

"barryvdh/laravel-dompdf": "^0.8.4",

而不是

"barryvdh/laravel-dompdf": "master@dev"

Answer 2

通常，在安装 third-party 包时，建议不要直接编辑 composer.json。您可以从文件中删除行 "barryvdh/laravel-dompdf": "master@dev"，然后从项目根目录中删除运行此命令：

composer require barryvdh/laravel-dompdf

它安装最新的稳定 third-party 包并自动更新 composer.json 和 composer.lock 文件。

更新：要解决 composer.json 文件的问题，请将存储库密钥更改为：

"repositories" : 
[
    {
        "type": "composer",
        "url": "https://packagist.org"
    },
    {
        "packagist": false
    }
]

Answer 3

在您的 composer.json 文件中删除这一行

"require": {
    "barryvdh/laravel-dompdf": "master@dev"
},

之后，运行在您的命令提示符中执行此命令

composer require barryvdh/laravel-dompdf

这还将下载软件包和 dompdf + fontlib 库。这将为您的项目生成最新版本

请检查：barryvdh/laravel-dompdf

Answer 4

从我的 composer.json 中删除存储库部分后安装了软件包。
