我是通过XAMPP在本地计算机上运行的。我试图安装几次，它仍然给我同样的错误。试图ping google.com，并显示没有错误（为了清除我自己，这不是DNS问题）。在GitHub问题上没有发现与此相关的具体内容。
当我尝试通过Composer要求barryvdh / laravel-dompdf时，我收到此错误。
Failed to download dompdf/dompdf from dist: The "https://api.github.com/repos/dompdf/dompdf/zipball/5113accd9ae5d466077cce5208dcf3fb871bf8f6" file could not be downloaded: php_network_getaddresses: getaddrinfo failed: No such host is known.

以下是bash的复制详情。
