Question

请参阅第2部分，其中列出了安装模块continued post时的最新错误。

通常当我尝试使用标准cpan＆gt;安装XML :: Xerces CPAN模块时安装XML :: Xercers比我在一些处理后得到以下错误消息：

XML-Xerces-2.7.0-0/samples/SEnumVal.pl

   WARNING

You have not defined any of the following environment variables:
   XERCESCROOT
   XERCES_LIB
   XERCES_INCLUDE

These instruct me how to locate the Xerces header files, and the
Xerces dynamic library. If they are installed in a standard system
directory, I will located them without those variables.

However, if they have been installed in a non-standard location
(e.g. '/usr/include/xerces'), then I will need help. See the README
for more info.

Proceeding ...

Without these I cannot find the config.status file that was used to
build your Xerces-C library. Without that file, I may not be able to properly
build the C++ glue files that come with Xerces.pm.

Proceeding anyway ...

将环境变量设置为/home/username/XML-Xerces-2.7.0-0/XML-Xerces-2.7.0-0/Xerces.pm后，请注意我不确定是否应将环境变量指向Xerces.pm或Xerces.cpp或Xerces-extra.pm或Xerces.i ，但是现在我将环境变量指向/home/username/XML-Xerces-2.7.0-0/XML-Xerces-2.7.0-0/Xerces.pm

按照上述设置环境变量并输入cpan>install XML::Xerces后，我收到以下消息：

注意：我尝试下载XML::Xerces并尝试再次安装它，既可以手动也可以使用CPAN，但我会收到上述错误消息。

可能的原因是什么，可以提出什么建议来解决这个问题呢？

更新：即使在构建Xerces-C之后，XML :: Xerces模块也没有构建，并且收到错误消息。

You are attempt to build XML::Xerces-2.7.0-0 using Xerces-C-2.8.0,
this will most likely fail, so I am aborting.

You must use Xerces-C-2.7.0

Answer 1

这是一般规则：任何名为“ROOT”的环境变量都要求的是目录，而不是文件。

但是，您似乎没有安装Xerces库，这在安装perl模块之前是必需的。我将引用您提供的输出的某些部分，因为您错过了下一步该做什么：

“... 这些指示我如何找到Xerces头文件和Xerces动态库 ......”

“没有这些，我找不到曾经使用的config.status文件 构建您的Xerces-C库“

那么，你安装了Xerces-C吗？在此之后安装Perl模块会有更好的结果。

Answer 2

您是否尝试使用PPM安装XML :: Xerces？

如何安装XML :: Xerces？
