Question

我正在尝试在Perlbrew下安装XML :: Simple，但是遇到了似乎需要root用户访问才能修复的错误。但是，使用perlbrew（或至少其中一个）的全部目的是使您的perl环境与操作系统安装的perl版本脱离关联。

我已经安装了perlbrew（5.10.1，传统代码要求）和几个模块。它目前正在按预期运行。但是，尝试安装XML :: Simple时出现错误。

$ cpanm XML::Simple

这是日志文件的输出（切至相关部分）：

我尝试通过以下方式在本地安装expat：

wget https://sourceforge.net/projects/expat/files/expat/2.2.4/expat-2.2.4.tar.bz2
tar xjf expat-2.2.4.tar.bz2
cd expat-2.2.4
./configure --prefix=/home/user1/perl5/perlbrew/perls/perl-5.10.1/
make
make install

我已验证expat.h在〜/ perl5 / perlbrew / perls / perl-5.10.1 / include中。我更新了路径以包含该位置。

我看到的每个修复都是通过操作系统工具安装expat（针对各种口味）。

问题是我没有超级用户访问权限，尽管我可以从技术上要求管理员安装它，但是我的项目需要一种不需要超级用户访问权限的解决方案，因为它将通过多个环境和服务器进行复制。 / p>

有没有办法安装XML :: Simple而没有外国人？还是一种在perlbrew中安装expat的方式，以便XML :: Simple可以找到并使用它？

手动安装XML::Parser，并告诉ExtUtils::MakeMaker在哪里找到C库。参见INC和LIBS。

cpanm --look XML::Parser
PERLPREFIX=/home/user1/perl5/perlbrew/perls/perl-5.10.1/
perl Makefile.PL INC=-I$PERLPREFIX/include LIBS=-L$PERLPREFIX/lib
make && make test && make install

如果使用cpan而不是cpanm，则可以使此操作永久生效。设置option makepl_arg，例如通过在CPAN shell提示符下运行）：

o conf makepl_arg "INC=-I/home/user1/perl5/perlbrew/perls/perl-5.10.1/include LIBS=-L/home/user1/perl5/perlbrew/perls/perl-5.10.1/lib"
o conf commit

P.S。 expat 2.2.5没了

无法在Perlbrew上安装XML :: Simple
