【问题描述】：

我厌倦了使用 perl 脚本并行运行多个作业，该脚本使用 parallel:ForkManager。

#!/usr/bin/perl  -w

use Parallel::ForkManager;

my @make_obj = qw(
 mode1_testlist
 mode1_testlist1
 mode1_testlist2
);

my $fm = $pm = Parallel::ForkManager-> new(3);
foreach my $obj (@make_obj) 
  $fm->start and next;
  print("make regression MODE=1 MODELIST=$make_obj");
  $fm->finish();

但它使我陷入错误。

无法在 @INC 中找到 Parallel/ForkManager.pm（@INC 包含：/usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/ site_perl/5.8.8 /usr/lib/perl5/site_perl /usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.8 /usr/lib/ perl5/vendor_perl /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/5.8.8 .) 在 parallel_run.pl 第 3 行。 BEGIN 失败——编译在 parallel_run.pl 第 3 行中止。

我已经下载了 Parallel-ForkManager-1.03.tar.gz 但我不知道放在哪里我的意思是如何安装它。

我试过 perl Makefile.PL && make test && make install

【参考方案1】：

随便用

cpan Parallel::ForkManager

或者，在确保已安装其依赖项（POSIX、Storable、File::Spec、File::Temp、File::Path 2.00 和 Test::More 0.81_01）后执行以下命令：

tar xvzf Parallel-ForkManager-1.03.tar.gz
cd Parallel-ForkManager-1.03
perl Makefile.PL && make test && make install

【讨论】：

它需要 File::Path 2.00 或更高版本，即使在 Makefile.PL 中没有指定版本。即使在 Makefile.PL 中指定了 0.80，它也需要 Test::More 0.81_01。

仅供参考，我不是该服务器的管理员。我需要并行运行一些工作！如果还有其他出路，比如一些脚本，请告诉我！

查看了这个 deps.cpantesters.org/… 的依赖关系，我认为你不需要安装所有依赖模块，因为它们是核心模块，所以它应该很容易与 perl 一起使用。 perl Makefile.PL && make test && make install 对我来说效果很好。当您运行此命令时，日志会显示什么内容？

@SuvasishSarker 我已经通过添加错误日志来编辑我的问题，这是我在运行perl Makefile.PL && make test && make install时得到的@

当我尝试安装 TEST:MORE make install 给我以下警告时！Warning: You do not have permissions to install into /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi at /usr/lib/perl5/5.8.8/ExtUtils/Install.pm line 114. Cannot forceunlink /usr/lib/perl5/5.8.8/Test/Builder.pm: Permission denied at /usr/lib/perl5/5.8.8/File/Find.pm line 924 我想我应该有管理员权限来安装它！

【参考方案2】：

就像已接受答案中的一些 cmets 所暗示的那样，可能缺少依赖项。以下对我有用：

cpan 升级测试::More

cpan Parallel::ForkManager

【参考方案3】：

你需要运行 dmake，而不是 make

perl Makefile.PL && dmake test && dmake install
