DBIx :: Class :: Schema :: Loader安装失败

Question

好吧，过去两天我一直在努力完成这项工作，重新安装依赖项，更新模块，但没有找到任何解决方案。

安装命令行：

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

我的测试失败，例如：

更新

正如abraxxa所建议的，我尝试了更新的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是因为我没有root权限。 我重新运行测试，它们再次失败。 但是，我看不出cpan安装过程中的perl版本已更改：

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

#          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.

第一行使用/usr/bin/perl代替

~/.perl/perl

我已更改$PATH以使用较新的perl版本，的确如此（请参阅perl -v行）。

我感到这里有些混乱。 我还尝试安装cpan[5]> install Devel::DProf并收到以下错误：无法加载'〜/ .cpan / build / Devel-DProf-20110802.00-cJFc6O / blib / arch / auto / Devel / DProf /DProf.so'用于模块Devel :: DProf：〜/ .cpan / build / Devel-DProf-20110802.00-cJFc6O / blib / arch / auto / Devel / DProf / DProf.so：未定义符号：/ usr / lib中的get_cvn_flags /perl5/5.8.8/x86_64-linux-thread-multi/DynaLoader.pm第230行。位于dprof / test8_t第0行。

如您所见，它尝试从/ usr / lib /而不是我的local :: lib加载DynaLoader。

Answer 1

DBIx :: Class维护者在很大程度上使其向下兼容其META文件中声明的Perl 5.8.1版本。 可能是某些其他组件（例如DBD :: SQLite或DBIx :: Class :: Schema :: Loader）在您的特定版本（RedHat Enterprise Linux 4？）上存在错误。 DBIx :: Class在其故障排除文档中甚至有一节： 红帽系统上的Perl性能问题

如果要安装自己的Perl，建议的方法是使用perlbrew 。 您甚至不需要root用户访问权限，您可以将其安装在主目录中，甚至可以安装多个完全分开的不同或相同版本的安装，例如每个应用程序一个。
