在Ubuntu运行Perl报错：

Can't locate XML/LibXML.pm in @INC (you may need to install the XML::LibXML module) (@INC contains: /etc/perl /usr/local/lib/x86_64-linux-gnu/perl/5.22.1 /usr/local/share/perl/5.22.1 /usr/lib/x86_64-linux-gnu/perl5/5.22 /usr/share/perl5 /usr/lib/x86_64-linux-gnu/perl/5.22 /usr/share/perl/5.22 /usr/local/lib/site_perl /usr/lib/x86_64-linux-gnu/perl-base .) at ./run_test.pl line 15.

尝试使用以下命令安装LibXML Perl模块：

sudo cpan install XML::LibXML

但是这个命令又遇到了麻烦。完整的输出是这样的：

If this is wrong, Re-run as:

Checking for ability to link against xml2…no

Try setting LIBS and INC values on the command line

Or get libxml2 from

http://xmlsoft.org/

If you install via RPMs, make sure you also install the -devel

RPMs, as this is where the headers (.h files) are.
Also, you may try to run perl Makefile.PL with the DEBUG=1 parameter

to see the exact reason why the detection of libxml2 installation

failed or why Makefile.PL was not able to compile a test program.

如何在Ubuntu或者任何其他基于Ubuntu的Linux发行版上安装LibXML模块。

如何在Ubuntu Linux上安装LibXML Perl模块

上面显示的错误输出中突出显示了LibXML安装失败的原因：

Checking for ability to link against libxml2…libxml2, zlib, and/or the Math library (-lm) have not been found.

显然，系统缺少libxml2和zlib库。要解决此问题，我们所需要做的就是使用以下命令安装所需的库：

sudo apt-get install zlib1g-dev libxml2-dev

一旦安装了库，就以常规方式继续安装LibXML Perl模块：

sudo cpan install XML::LibXML
