php - 无法安装 barryvdh/laravel-dompdf

问题描述

我无法barryvdh/laravel-dompdf使用composer require barryvdh/laravel-dompdf.

我得到的错误是：

[无效参数异常] 找不到 barryvdh/laravel-dompdf 的匹配版本。检查包拼写、您的版本约束以及该包的稳定性是否与您的最低稳定性 (dev) 相匹配。

因此，为了修复错误，我将其包含barryvdh/laravel-dompdf: master@dev在 composer.json 中并做了一个composer update. 这次它给了我错误：

在任何版本中都找不到请求的包 barryvdh/laravel-dompdf。包名可能有错别字

下面是我的composer.json：
