Question

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

我得到的错误是：

[无效的参数异常]找不到匹配版本的barryvdh / laravel-dompdf。检查程序包的拼写，版本约束以及程序包的稳定性是否与最低稳定性（dev）相匹配。

因此，为了纠正错误，我在composer.json中加入了barryvdh/laravel-dompdf: master@dev并做了一个composer update。这次它给了我错误：

在任何版本中都找不到所请求的软件包barryvdh / laravel-dompdf。包裹名称中可能有错字

下面是我的composer.json：

您认为我在这里想念什么？

Answer 1

使用

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

代替

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

Answer 2

通常，建议在安装第三方软件包时不要直接编辑composer.json。您可以从文件中删除行"barryvdh/laravel-dompdf": "master@dev"，然后从项目根目录运行此命令：

composer require barryvdh/laravel-dompdf

它将安装最新的稳定的第三方软件包，并自动更新composer.json和composer.lock文件。

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

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

Answer 3

在您的composer.json文件中删除此行

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

之后，在命令提示符下运行此命令

composer require barryvdh/laravel-dompdf

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

Answer 4

从我的composer.json中删除存储库部分后，安装了该软件包。
