只是试图安装一个CPAN模块，似乎没有丢失任何先决条件，似乎找不到任何指向我需要做什么来解决这个问题的东西。有人能理解这个问题可能是什么吗？我宁愿不强制安装，除非我绝对肯定它可能只是一个问题的测试。我看过以前的问题，问题几乎总是一个失踪的prereq模块，但似乎没有这里的情况。

XML-Liberal-0.30中有两个bug。
不建议强制安装该模块。
下面将修复问题并安装发行版：

wget https://cpan.metacpan.org/authors/id/M/MI/MIYAGAWA/XML-Liberal-0.30.tar.gz
tar xvzf XML-Liberal-0.30.tar.gz
cd XML-Liberal-0.30
perl -pe's/mandate/mandates?/' -i~ lib/XML/Liberal/Remedy/StandaloneAttribute.pm
perl -pe's/->extract_error\(\K\$\@/"\$\@"/' -i~ lib/XML/Liberal.pm
perl -I . Makefile.PL
make test
make install

该模块的逻辑基本如下：
1.默认情况下最多15次：
1.尝试使用XML：：LibXML解析文档，同时捕获错误。
1.如果没有发生错误，
1.成功（返回）
1.对于每个错误消息，
1.对XML应用修复程序以尝试解决错误。
1.失败
现在的问题是libxml 2已经改变了它的一些错误消息。

parser error : Specification mandate value for attribute ...

但是语法错误被修正了。

parser error : Specification mandates value for attribute ...

修复方法很简单，在lib/XML/Liberal/Remedy/StandaloneAttribute.pm中，

my ($attr) = $error->message =~
        /^parser error : Specification mandate value for attribute (\w+)/
            or return 0;

与

my ($attr) = $error->message =~
        /^parser error : Specification mandates? value for attribute (\w+)/
            or return 0;

（我假设libxml 2的某些版本返回Specification mandate value。网络搜索似乎证实了这一点。）
第二个问题是它如何解析错误消息。

my $error = $self->extract_error($@, \$xml);

与

my $error = $self->extract_error("$@", \$xml);

XML/Liberal.pm.
