构建dssp时无法找到Data / Dumper.pm-已安装perl但找不到？

问题描述

我正在尝试在服务器节点（而不是服务器登录）上构建dssp（https://github.com/cmbi/dssp），并且我正面临系统如何查找依赖项的问题。我正在使用centos 7。

构建dssp的过程是：run ./autogen获得configure.sh文件，然后执行该文件。然后运行make。

运行whereis perl和whereis perl5我得到：

[mavridks@haswell-182 dssp-2.3.0]$ whereis perl
perl: /usr/bin/perl /usr/share/man/man1/perl.1.gz

[mavridks@haswell-182 dssp-2.3.0]$ whereis perl5
perl5: /usr/lib64/perl5 /usr/share/perl5

然后运行./autogen，我得到了错误：

Can't locate Data/Dumper.pm in @INC
   (@INC contains:
   /hits/sw/shared/apps/Autoconf/2.69-GCC-4.8.4/share/autoconf

（添加了换行符以提高可读性。）

在我看来，调用autoconf时出现此错误是与无法正确定位Perl文件或具有比应有的路径更多有关？另一个想法是我在服务器上没有root特权，也许这会引起问题？

欢迎任何想法或建议。

注意：服务器使用模块系统来加载各种依赖项。我需要自动工具和Boost。我正在使用的模块（如果这很重要）是

在HåkonHægland发表评论后，我得到了：

在提供了许多有用的评论和答案之后，我添加了更多信息：

第一个连接到服务器登录节点。运行whereis perl会给出：

[mavridks @ haswell-login〜] $ whereis perl

perl：/ usr / bin / perl /usr/share/man/man1/perl.1.gz

也可以运行

[mavridks@haswell-login ~]$ perl --version

This is perl 5,version 16,subversion 3 (v5.16.3) built for x86_64- 
linux-thread-multi
(with 39 registered patches,see perl -V for more detail)

。最后一个得到：

[mavridks@haswell-login ~]$ perl -MData::Dumper -E 'say 
$INC{"Data/Dumper.pm"}'
/usr/lib64/perl5/vendor_perl/Data/Dumper.pm

旁注：运行perl -V会得到什么？

    /usr/lib64/perl5
    /usr/share/perl5
    .

然后连接到一个gpu节点。看来我们仍然有相同的perl：

[mavridks @ haswell-179〜] $ whereis perl perl：/ usr / bin / perl /usr/share/man/man1/perl.1.gz

但是现在Data / Dumber不再可用了（运行perl -MData :: Dumper -E'say $ INC {“ Data / Dumper.pm”}'））：

[mavridks@haswell-179 ~]$ perl -MData::Dumper -E 'say $INC{"Data/Dumper.pm"}'
Can't locate Data/Dumper.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .).
BEGIN Failed--compilation aborted.

然后，IT部门建议加载perl模块。服务器建立在模块系统上，其中所有组都可以将软件作为模块加载（在路径中附加正确的文件-这是https://lmod.readthedocs.io/en/latest/#overview使用的系统）。因此，如果我们运行模块加载Perl，我们将：

[mavridks @ haswell-179〜] $ whereis perl perl：/ usr / bin / perl /hits/sw/shared/apps/Perl/5.30.0-GCCcore-8.3.0/bin/perl /usr/share/man/man1/perl.1.gz

这意味着我们已经更改了某些内容（我可以说使用的分布是什么？）。但是现在我们有了：

[mavridks@haswell-179 ~]$ perl -MData::Dumper -E 'say $INC{"Data/Dumper.pm"}'
/hits/sw/shared/apps/Perl/5.30.0-GCCcore-8.3.0/lib/perl5/5.30.0/x86_64-linux-thread-multi/Data/Dumper.pm

这意味着我们在系统上有数据/转储器。

最后，还需要将所有自动工具作为模块加载。然后，似乎autogen.sh脚本的执行是在系统中寻找perl模块（一个来自login而不是gpu的模块），但是当然找不到它们。

[mavridks @ haswell-179 dssp-2.3.0] $ ./autogen.sh 无法在@INC中找到Data / Dumper.pm（@INC包含：/hits/sw/shared/apps/Autoconf/2.69-GCC-4.8.4/share/autoconf / usr / local / lib64 / perl5 / usr /本地/共享/ perl5 / usr / lib64 / perl5 / vendor_perl / usr / share / perl5 / vendor_perl / usr / lib64 / perl5 / usr / share / perl5。）在/hits/sw/shared/apps/Autoconf/2.69-GCC -4.8.4 / share / autoconf / Autom4te / C4che.pm第33行。 BEGIN失败-在/hits/sw/shared/apps/Autoconf/2.69-GCC-4.8.4/share/autoconf/Autom4te/C4che.pm第33行中，编译中止。在/hits/sw/shared/apps/Autoconf/2.69-GCC-4.8.4/bin/autom4te第37行，要求中的编译失败。 BEGIN失败-编译在/hits/sw/shared/apps/Autoconf/2.69-GCC-4.8.4/bin/autom4te第37行中止。 aclocal：错误：回显失败，退出状态：2

解决方法

您已经安装了两个perl版本。

/usr/bin/perl，v5.16.3 ^[1]
/hits/sw/shared/apps/Perl/5.30.0-GCCcore-8.3.0/bin/perl，v5.30.0 ^[2]

我将分别命名为“系统perl”和“模块化perl”。

系统perl未安装Data :: Dumper。^[3]
模块化perl确实安装了Data :: Dumper。^[4]

whereis在您的PATH中仅显示系统perl，但以后的命令显示perl调用模块化perl。因此，perl是模块化perl的别名，^[5]，或者您在不同的环境中运行测试（即，更改了PATH）。

设置PERL5LIB是否合适？

有一次，您将环境变量PERL5LIB设置为/hits/sw/shared/apps/Perl/5.30.0-GCCcore-8.3.0/lib/perl5/5.30.0。这不合适。

这对于系统perl是不正确的。^[6]

对于模块化perl，这是不必要的。这是多余的。^[7]

为什么系统perl上没有安装Data :: Dumper？

Perl随附某些模块。实际上，只要Perl中一直存在对模块的支持，就包括Data :: Dumper。 Data :: Dumper应该始终可用。

但是，某些Linux发行版将Perl分为多个软件包。似乎在CentOS 7的perl(Data::Dumper) package中找到了Data :: Dumper。

因此解决方案是安装该软件包。

由于Data :: Dumper具有双重作用，因此也可以从CPAN安装它。这不需要任何特殊权限。也就是说，我通常建议在本地安装perl而不是弄乱系统perl。看来您已经有了这样的Perl。这会将我们引向下一个子答案。

我要使用模块化的perl怎么办？

我不确定。

快速实验使我相信，只需将模块化perl放在/usr/bin之前的PATH中即可解决。

export PATH="/hits/sw/shared/apps/Perl/5.30.0-GCCcore-8.3.0/bin:$PATH"

或者，快速实验表明以下两种方法也可以工作：

./configure PERL=/hits/sw/shared/apps/Perl/5.30.0-GCCcore-8.3.0/bin/perl

PERL=/hits/sw/shared/apps/Perl/5.30.0-GCCcore-8.3.0/bin/perl ./configure

如果这些方法不能解决问题，可以将其作为一个单独的问题进行询问。

如果我不同意此答案中的某些内容怎么办？

我的某些陈述是猜测。例如，问题中的任何地方都没有提到/hits/sw/shared/apps/Perl/5.30.0-GCCcore-8.3.0/bin/perl。如果您认为我做错了，请提供以下命令的输出（parens和全部）：
