DBIx :: Class :: Schema :: Loader安裝失敗

Question

那麼，我一直試圖在過去兩天得到這個工作，重新安裝依賴關係，更新模塊，但我還沒有找到任何解決方案。

安裝的命令行：

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

我得到失敗的測試，如：

UPDATE

由於abraxxa建議，我嘗試了新的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，因爲我沒有root權限。 我重新運行測試，並再次失敗。 不過，我沒有看到的perl版本在CPAN已經改變了安裝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

我已經改變了我對$PATH使用更新的Perl版本，實際上它是（請參閱perl -v行）。

我覺得這裏有東西搞砸了。我也嘗試安裝cpan[5]> install Devel::DProf，並得到以下錯誤： 無法爲模塊Devel加載'〜/ .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，它會嘗試從/ usr/lib /而不是local :: lib加載DynaLoader我有。

DBIx :: Class維護者採用了一種很大的方式使其向下兼容版本爲在其META文件中聲明的Perl 5.8.1。可能是某些其他組件（如DBD :: SQLite或DBIx :: Class :: Schema :: Loader）在您的特定版本（RedHat Enterprise Linux 4？）上存在一個錯誤。 DBIx :: Class在其疑難解答文檔中甚至有一節：Perl Performance Issues on Red Hat Systems

如果要安裝自己的Perl，推薦的方法是使用perlbrew。您甚至不需要root訪問權限，您可以將它安裝在您的主目錄中，甚至可以安裝多個完全分離的不同版本或不同版本的安裝，例如每個應用程序一個。
