perl - 所有 CPAN 镜像都不能在 CPAN 配置中工作？

Question

我正在尝试在 Centos 6 上安装和配置 CPAN。

我在配置中收到此消息:

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. Would you like to configure as much as possible automatically? [yes]

我选择了是，然后系统提示我这条消息:

Autoconfigured everything but 'urllist'. Now you need to choose your CPAN mirror sites. You can let me pick mirrors for you, you can select them from a list or you can enter them by hand. Would you like me to automatically choose some CPAN mirror sites for you? (This means connecting to the Internet) [yes]

我还选择了是来接收该消息:

Your urllist is empty! The urllist can be edited. E.g. with 'o conf urllist push ftp://myurl/'

Could not fetch MIRRORED.BY We failed to get a copy of the mirror list from the Internet. You will need to provide CPAN mirror URLs yourself.

Now you can enter your own CPAN URLs by hand. A local CPAN mirror can be listed using a 'file:' URL like 'file:///path/to/cpan/'

CPAN.pm needs at least one URL where it can fetch CPAN files from.

Please enter your CPAN site: []

然后我检查了perlmodlib中的镜像列表对于荷兰(我住的地方)，我一一输入，配置终止如下。

Please enter your CPAN site: [] ftp://ftp.quicknet.nl/pub/CPAN/ Enter another URL or ENTER to quit: [] http://mirror.hostfuss.com/CPAN/ Enter another URL or ENTER to quit: [] ftp://mirror.hostfuss.com/CPAN/ Enter another URL or ENTER to quit: [] http://mirrors3.kernel.org/cpan/ Enter another URL or ENTER to quit: [] ftp://mirrors3.kernel.org/pub/CPAN/ Enter another URL or ENTER to quit: [] http://cpan.mirror.versatel.nl/ Enter another URL or ENTER to quit: [] ftp://ftp.mirror.versatel.nl/cpan/ Enter another URL or ENTER to quit: [] ftp://download.xs4all.nl/pub/mirror/CPAN/ Enter another URL or ENTER to quit: [] http://mirror.leaseweb.com/CPAN/ Enter another URL or ENTER to quit: [] ftp://mirror.leaseweb.com/CPAN/ Enter another URL or ENTER to quit: [] ftp://ftp.cpan.nl/pub/CPAN/ Enter another URL or ENTER to quit: [] http://archive.cs.uu.nl/mirror/CPAN/ Enter another URL or ENTER to quit: [] ftp://ftp.cs.uu.nl/mirror/CPAN/ Enter another URL or ENTER to quit: [] http://luxitude.net/cpan/ Enter another URL or ENTER to quit: []

Autoconfiguration complete.

You can re-run configuration any time with 'o conf init' in the CPAN shell

现在，每当我尝试安装任何模块时，都会出现错误，例如尝试安装 XML::Simple ，我在试验结束时得到以下信息:

Please check, if the URLs I found in your configuration file (ftp://ftp.quicknet.nl/pub/CPAN/, http://mirror.hostfuss.com/CPAN/, ftp://mirror.hostfuss.com/CPAN/, http://mirrors3.kernel.org/cpan/, ftp://mirrors3.kernel.org/pub/CPAN/, http://cpan.mirror.versatel.nl/, ftp://ftp.mirror.versatel.nl/cpan/, ftp://download.xs4all.nl/pub/mirror/CPAN/, http://mirror.leaseweb.com/CPAN/, ftp://mirror.leaseweb.com/CPAN/, ftp://ftp.cpan.nl/pub/CPAN/, http://archive.cs.uu.nl/mirror/CPAN/, ftp://ftp.cs.uu.nl/mirror/CPAN/, http://luxitude.net/cpan/) are valid. The urllist can be edited. E.g. with 'o conf urllist push ftp://myurl/'

Could not fetch authors/01mailrc.txt.gz Lockfile removed.

我该如何解决这个问题？

您似乎在代理后面。您必须在 CPAN shell 中配置代理:

o conf http_proxy 'http://user:password@proxy.com'
