如何安装 XML::Xerces？

Question

请参阅第 2 部分，其中列出了安装模块时的最新错误续帖。

通常，当我尝试使用标准 cpan> 安装 XML::Xerces CPAN 模块时，安装 XML::Xercers 比我在一些处理后收到以下错误消息：

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 ...

   WARNING

You have not defined any of the following environment variables:

   XERCES_CONFIG

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 后。 pm，请注意，我不确定是否应该将环境变量指向 Xerces.pm 或 Xerces.cpp 或 Xerces-extra.pm< /code> 或 Xerces.i，但目前我将环境变量指向 /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： 我已尝试下载 XML::Xerces 并尝试再次安装它，无论是手动还是使用 CPAN，但我收到上述错误消息。

可能的原因是什么？可以建议采取什么措施来解决这个问题？

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

Update2这是收到的错误，它表示存在某种版本不匹配。

      *** Version Mismatch ***

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

一般规则如下：任何名为“ROOT”之类的环境变量都要求提供目录，而不是文件。

但是，您似乎没有安装 Xerces 库，而这是安装 perl 模块之前所必需的。我将引用您提供的输出的某些部分，作为您错过的下一步操作的提示：

---

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

“如果没有这些，我无法找到用于的 config.status 文件
构建您的 Xerces-C 库”

---

那么，您是否安装了 Xerces-C< /a>? 之后安装 Perl 模块会得到更好的结果。

Answer 2

您是否尝试使用 PPM 安装 XML::Xerces？
