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：

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

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.

-> 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.

这是系统信息：

Answer 1

我认为相关的一行是：

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

为什么要为此使用CPAN呢？如果您拥有标准操作系统安装程序提供的本机软件包，则通常非常糟糕地安装CPAN软件包。

Ubuntu本身提供了许多Perl包，具有以下命名约定：包名始终以lib开头，然后Perl包名称如XML::LibXML被转换为小写并且::被替换要点击-（XML::LibXML =＆gt; xml-libxml），最后添加-perl后缀。换句话说，XML::LibXML的原生包名称为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此软件包，可以使用sudo apt-get remove将其卸载。如果您使用CPAN，则很难可靠地卸载它。

Answer 3

忽略了显而易见的事实：

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

此模块建立并成功安装后
