如何在Ubuntu上安装XML :: LibXML

Question

这是安装的标准输出：

$sudo cpanm XML::LibXML
--> Working on XML::LibXML
Fetching http://www.cpan.org/authors/id/S/SH/SHLOMIF/XML-LibXML-2.0014.tar.gz ... OK
Configuring XML-LibXML-2.0014 ... N/A
! Configure failed for XML-LibXML-2.0014. See /home/kahmed/.cpanm/build.log for details.

细节：

Unpacking XML-LibXML-2.0014.tar.gz
Entering XML-LibXML-2.0014
Checking configure dependencies from META.yml
Checking if you have ExtUtils::MakeMaker 0 ... Yes (6.55_02)
Configuring XML-LibXML-2.0014
Running Makefile.PL
enable native perl UTF8
running xml2-config...ok (2.9.0)
Checking for ability to link against xml2...no
Checking for ability to link against libxml2...libxml2, zlib, and/or the Math library (-lm) have not been found.
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.
-> N/A
-> FAIL Configure failed for XML-LibXML-2.0014. See /home/kahmed/.cpanm/build.log for details.

我尝试手动安装libxml2，但仍然遇到同样的问题。

另外，我检查了libxml2-dev：

 sudo apt-get install libxml2-dev
Reading package lists... Done
Building dependency tree       
Reading state information... Done
libxml2-dev is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 78 not upgraded.

这是系统信息：

Answer 1

我认为相关的是：

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

所以，你已经覆盖了libxml。 你安装了适当的zlib包吗？ 尝试：

sudo apt-get install zlib1g-dev

然后再次尝试安装XML :: LibXML。

Answer 2

你为什么要为此使用CPAN呢？ 如果您具有标准操作系统安装程序提供的本机程序包，则通常非常不明智地安装CPAN程序包。

Ubuntu的提供了很多的Perl包本身，具有以下命名约定：包名称总是开头lib ，像然后Perl包名称XML::LibXML被转换为小写和::更换冲- XML::LibXML => xml-libxml ），最后添加-perl后缀。 换句话说， XML::LibXML本机包名称是libxml-libxml-perl 。

因此，在您的情况下，您只需运行此命令，它将自动提取所有必需的依赖项：

sudo apt-get install libxml-libxml-perl

如果您因任何原因不喜欢这个软件包，可以使用sudo apt-get remove卸载它。 如果使用CPAN，则很难可靠地卸载它。

Answer 3

忽略了显而易见的：

sudo apt-get install --reinstall zlibc zlib1g zlib1g-dev

然后：

sudo cpanm XML::LibXML

作品！

Answer 4

也许这是新版本。 我做了：

sudo apt-get install libxml2-dev

此模块构建并成功安装后
