DBIx :: Class :: Schema :: Loader安装失败

Question

那么，我一直试图在过去两天得到这个工作，重新安装依赖关系，更新模块，但我还没有找到任何解决方案。

安装的命令行：

$> cpan DBIx::Class::Schema::Loader 

我得到失败的测试，如：

UPDATE

由于abraxxa建议，我尝试了新的perl版本：

icsl8684> perl -v 

This is perl 5, version 12, subversion 2 (v5.12.2) built for x86_64-linux 

另外，我使用local :: lib，因为我没有root权限。 我重新运行测试，并再次失败。 不过，我没有看到的perl版本在CPAN已经改变了安装proccess：

PERL_DL_NONLAZY=1 /usr/bin/perl "-MExtUtils::Command::MM" "-e" "test_harness(0, 'inc', 'blib/lib', 'blib/arch')" t/*.t t/backcompat/0.04006/*.t 
t/01use.t ............................... ok  
t/02pod.t ............................... ok  
t/10_01sqlite_common.t .................. 6/294 
# Failed test 'Correct number of warnings' 
# at t/lib/dbixcsl_common_tests.pm line 323. 
#   got: '10' 
#  expected: '9' 
# Column 'dbix_class_testcomponent' in table 'loader_test2' collides with an inherited method. 
# See "COLUMN ACCESSOR COLLISIONS" in perldoc DBIx::Class::Schema::Loader::Base . 
# Column 'dbix_class_testcomponentmap' in table 'loader_test2' collides with an inherited method. 

第一行是使用/usr/bin/perl代替

~/.perl/perl

我已经改变了我对$PATH使用更新的Perl版本，实际上它是（请参阅perl -v行）。

我觉得这里有东西搞砸了。我也尝试安装cpan[5]> install Devel::DProf，并得到以下错误： 无法为模块Devel加载'〜/ .cpan/build/Devel-DProf-20110802.00-cJFc6O/blib/arch/auto/Devel/DProf/DProf.so' :: DProf：〜/ .cpan/build/Devel-DProf-20110802.00-cJFc6O/blib/arch/auto/Devel/DProf/DProf.so：undefined symbol：get_cvn_flags在/usr/lib/perl5/5.8.8/x86_64 -linux-thread-multi/DynaLoader.pm line 230. at dprof/test8_t line 0.

正如您所看到的，它会尝试从/ usr/lib /而不是local :: lib加载DynaLoader我有。

DBIx :: Class维护者采用了一种很大的方式使其向下兼容版本为在其META文件中声明的Perl 5.8.1。可能是某些其他组件（如DBD :: SQLite或DBIx :: Class :: Schema :: Loader）在您的特定版本（RedHat Enterprise Linux 4？）上存在一个错误。 DBIx :: Class在其疑难解答文档中甚至有一节：Perl Performance Issues on Red Hat Systems

如果要安装自己的Perl，推荐的方法是使用perlbrew。您甚至不需要root访问权限，您可以将它安装在您的主目录中，甚至可以安装多个完全分离的不同版本或不同版本的安装，例如每个应用程序一个。
