尝试通过PEAR安装CAS时出现php_network_getaddress错误

我按照说明安装PHPCA

加梨 最新稳定版本（当前1.3.4）： 安装新的

        pear install  https://developer.jasig.org/cas-clients/php/current.tgz

但是我得到了这个错误

$> sudo pear install  https://developer.jasig.org/cas-clients/php/current.tgz
downloading current.tgz ...
Starting to download current.tgz (96,108 bytes)
.....................done: 96,108 bytes
Connection to `__uri:443' failed: php_network_getaddresses: getaddrinfo failed: Name or service not known

我在谷歌上搜索了一下，没有找到任何关于PEAR的

php\u network\u getaddresses

我的curl或wget库（PEAR使用的）似乎很好：

如何解决此错误

我也试着用我的安装程序来安装这个软件包，但得到了相同的错误。包本身可能有问题。 尝试下载文件并从本地源安装
