我目前正在尝试用以下方式安装这个模块：

perl -MCPAN -e shell install XML::Parser::Style::Tree

它没有把它安装上，但安装了CPAN。在CPAN内，我再次执行了以下命令：

install XML::Parser::Style::Tree

起初，进程还算顺利。随后突然收到这些错误信息：

Can't locate File/ShareDir/Install.pm in @INC (@INC contains: ./inc /etc/perl /usr/local/lib/perl/5.10.1 /usr/local/share/perl/5.10.1 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.10 /usr/share/perl/5.10 /usr/local/lib/site_perl .) at Makefile.PL line 7.

因此，我愿意听取关于如何解决问题的建议。

解决方案

File::ShareDir::Install 是XML-Parser发行版的前提条件。

File::ShareDir::Install 尚未安装。

它被声明为依赖项，因此安装程序本应已安装它，但在访问一个关键文件时遇到了问题：

无法读取 '/home/leopoldo/.cpan/build/XML-Parser-2.58-jE9k8s/META.yml'。

请调整构建目录的权限。
