我试图安装一个包。连接到soft-download.org 失败。我不知道它为什么要尝试连接到该主机。

我尝试重新加载索引，但它仍然尝试访问soft-download.org。

【解决方案2】：

解决方案 1：删除坏存储库

不带参数运行cpan，然后输入

o conf urllist

这将列出要使用的存储库。

urllist
    0 [http://good1/]
    1 [http://good2/]
    2 [http://bad/]

重新输入没有坏的存储库，如下所示：

o conf urllist http://good1/ http://good2/

最后，按如下方式保存您的更改：

o conf commit

解决方案 2：找到最适合您的存储库

不带参数运行cpan，然后输入

o conf init urllist

当被问到“你想让我自动选择一些 CPAN 镜像吗？适合您的网站？”，按 Enter。

最后，按如下方式保存您的更改：

o conf commit

解决方案 3：按区域查找存储库

不带参数运行cpan，然后输入

o conf init urllist

当被问到“你想让我自动选择一些 CPAN 镜像吗？您的网站？”，输入no。

当询问“您要编辑 urllist 还是从列表中选择新镜像？”时，按 Enter。

当被问到“我应该使用缓存的镜像列表吗？”时，输入no。

按照提示选择镜像。

最后，按如下方式保存您的更改：

o conf commit
