Question

我正在尝试使用HTML::WikiConverter::MediaWiki安装的yum install perl-HTML-WikiConverter-MediaWiki.noarch。

根据perldoc我应该

use HTML::WikiConverter;
my $wc = new HTML::WikiConverter( dialect => 'MediaWiki' );

然后我得到了

Can't locate HTML/WikiConverter.pm in @INC (@INC contains: /usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/site_perl/5.8.8 /usr/lib/perl5/site_perl /usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.8 /usr/lib/perl5/vendor_perl /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/5.8.8 .) at ./test.pl line 3.
BEGIN failed--compilation aborted at ./test.pl line 3.

如果我尝试

use HTML::WikiConverter::MediaWiki;
my $wc = new HTML::WikiConverter( dialect => 'MediaWiki' );

然后我得到

Can't locate object method "new" via package "HTML::WikiConverter" at ./test.pl line 4.

如果我尝试

use HTML::WikiConverter::MediaWiki;
my $wc = new HTML::WikiConverter::MediaWiki( dialect => 'MediaWiki' );

然后我得到

Can't locate object method "new" via package "HTML::WikiConverter::MediaWiki" at ./test.pl line 4.

问题

有人能看出什么问题吗？

Answer 1

您没有安装HTML::WikiConverter。所以，安装它。从命令行，执行

cpan HTML::WikiConverter

并且不仅要安装HTML::WikiConverter，还应安装任何缺少的先决条件。

此外，根据您的用户权限，您可能需要以root身份运行该命令（即sudo cpan HTML::WikiConverter）。

Answer 2

听起来您没有在需要的地方安装基本行为HTML::WikiConverter。我不知道为什么HTML::WikiConverter::MediaWiki中的use base没有失败。 HTML::WikiConverter是与HTML::WikiConverter::MediaWiki的单独分发，而HWM使用HW的构造函数，因此如果您无法加载此模块，则Perl无法识别new的分派。

Answer 3

当您运行yum install perl-HTML-WikiConverter-MediaWiki.noarch时，您是否获得了任何提及安装perl-HTML-WikiConverter的输出？

您从运行rpm -q perl-HTML-WikiConverter和rpm -q perl-HTML-WikiConverter-MediaWiki获得了哪些输出。

您运行的是哪个版本的Perl（perl -v），它安装在哪里（which perl）以及它是如何安装的（使用yum或下载源代码并编译它）？

我怀疑您的系统在安装了yum的CPAN模块和cpan-install CPAN模块之间感到困惑。将两者混合在同一系统上永远不是一个好主意。如果要使用Perl的系统版本，则只使用yum安装CPAN模块。如果要使用cpan（或cpanp或cpanm）安装CPAN模块，请构建自己的Perl版本，并将其安装在远离标准Perl位置的位置。

为什么这个错误“找不到对象方法新”？
