请在安装模块时查看第2部分列出最新错误 继续发布.

通常，当我尝试使用标准CPAN安装XML :: XERCES CPAN模块> Install XML :: Xercers比我在处理后的以下错误消息：

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

XML-Xerces-2.7.0-0/postSource.pl

Removing previously used /home/adoshi/.cpan/build/XML-Xerces-2.7.0-0

  CPAN.pm: Going to build J/JA/JASONS/XML-Xerces-2.7.0-0.tar.gz


   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:
   XERCESCROOT
   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 ...

Running make install

将环境变量设置为 /home/username/XML-Xerces-2.7.0-0/XML-Xerces-2.7.0-0/Xerces.pm, ，请注意，不确定我是否应该将环境变量指向 Xerces.pm 或者 Xerces.cpp 或者 Xerces-extra.pm 或者 Xerces.i, ，但就目前而言，将环境变量指向 /home/username/XML-Xerces-2.7.0-0/XML-Xerces-2.7.0-0/Xerces.pm

在设置环境变量之后，如上所述并输入 cpan>install XML::Xerces 我得到以下消息：

笔记： 我尝试下载 XML::Xerces并尝试再次安装它，无论是手动还是使用CPAN，但是都上述错误消息。

有什么可能的原因，可以建议解决这个问题？

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

[adoshi@upc01.dev XML-Xerces-2.7.0-0]$ perl Makefile.PL

Using XERCES_INCLUDE = /adoshi/include/xerces

 properly build the C++ glue files that come with Xerces.pm.

Proceeding anyway ...

Update2这是遇到的错误，它说版本不匹配有些不匹配。

      *** 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
有帮助吗？

解决方案

这是一个通用规则：任何名为“ root”的环境变量都要求目录，而不是文件。

但是，似乎您已经安装了Xerces库，这是在安装Perl模块之前所必需的。我将引用您提供的输出的某些部分，这是您错过下一步做什么的提示：

"...这些指示我如何找到Xerces标头文件，以及Xerces Dynamic Library..."

“没有这些，我找不到config.status文件 它用于构建您的Xerces-c库"

所以，你安装了 Xerces-c？此后，您将有更好的结果安装PERL模块。

其他提示

您是否尝试使用PPM安装XML :: Xerces？
