Question

我正在尝试使用 cpan App::cpanminus 安装 App::cpanminus Perl 模块。我收到以下错误。如何修复错误并安装模块？

Answer 1

更新：尽管下面的答案对我有用，但我后来了解到更好的答案，以及对根本原因的正确解释。请参阅上面 ikegami 的答案，了解首选和接受的方法。出于历史目的保留下面的答案，因为它也有效。

~~错误的原因是文件02packages.details.txt.gz，and/or可能其他文件已损坏。~~移动.cpan目录到新目录位置并再次重新运行命令。它现在应该可以工作了。

cd && mv .cpan .cpan-bak
cpan App::cpanminus

打印：

CPAN.pm requires configuration, but most of it can be done automatically.
If you answer 'no' below, you will enter an interactive dialog for each
configuration option instead.

Answer 2

在我看来，有人尝试使用多种方法下载文件，但都失败了，没有文件或文件为空。

这表明存在网络问题。您需要解决网络问题才能继续。也许您需要使用不同的镜像，或者可能需要引导下载者使用代理。

请注意，您可以删除该文件，强制再次尝试下载它。

更新：我检查了 URL 的有效性，您的 cpan 配置为使用 (http://mirrors.ccs.neu.edu/CPAN)，它是错误的。无法解析名称 mirrors.ccs.neu.edu。因此，您需要配置 cpan 以使用不同的镜像。

要告诉 cpan 使用其他东西，运行 cpan。从内部，使用 o conf init urllist 或 o conf urllist http://www.cpan.org/。不要忘记在退出前使用 o conf commit 保存设置 (quit)。

你也可以使用像

这样的东西

printf '%s\n%s\n' 'o conf urllist http://www.cpan.org/' 'o conf commit' | cpan
