cpan 配置错误-如何更改？

我似乎错误地配置了垃圾邮件，现在正试图更改它。我在其他地方读到删除 /root/.cpam 的方法，我照做了，但这并没有帮助我获得启动对话框。

当我在控制台中输入 o config 时，我得到了：

perl -MCPAN -e shell
Terminal does not support AddHistory.

ReadLine support available (try 'install Bundle::CPAN')

显然，当我尝试安装 DateTime 模块时我做错了什么。

我该如何修复？我使用的是 suse 10.3

答案1

摘录自人CPAN如下：

o conf init稍后，可以通过在 CPAN shell 中发出命令来再次启动配置对话框。可以通过发出命令来运行配置对话框的子集o conf init WORD，其中 WORD 是任何有效的配置变量或正则表达式。

答案2

CPAN.pm 配置保存在~/.cpan/CPAN/MyConfig.pm您就可以编辑该文件。

如果您想通过 shell 更改 CPAN.pm 配置。运行cpan不带参数的命令以进入 shell。从那里，o conf将显示所有选项。o conf OPTION将显示某些内容的当前值，并o conf OPTION VALUE设置新值。完成后，使用o conf commit保存更改。请参阅CPAN::首次了解选项的详细信息。

$ cpan
Terminal does not support AddHistory.

To fix that, maybe try>  install Term::ReadLine::Perl

Enter 'h' for help.
