如何在macOS上安装perl模块? [英] how do I install perl modules on macos?

问题描述

线程>安装缺少的Perl的最简单方法是什么模块?，我做了

The thread perl how can I append STDOUT of list form system call of perl script to a file led to the following solution: use IPC::Run qw( run );. On my macos 10.14.6 running perl 5.18.4, this threw an error: Can't locate IPC/Run.pm in @INC (you may need to install the IPC::Run module). Accordingly, following What's the easiest way to install a missing Perl module?, I did

> cpan IPC::Run
<snip: 403 lines later>
Appending installation info to /Users/BNW/perl5/lib/perl5/darwin-thread-multi-2level/perllocal.pod
  TODDR/IPC-Run-20180523.0.tar.gz
  /usr/bin/make install  -- OK

，然后重新启动了MacBookPro.然后我编辑了Perl脚本bosswrap.pl以开始

and rebooted my MacBookPro. And I edited my perl script, bosswrap.pl, to start

#!/usr/bin/perl
use strict; use warnings;
use IPC::Run qw( run );

但这又会引发与以前相同的错误:

but this again throws apparently the same error as before:

> bosswrap.pl
Can't locate IPC/Run.pm in @INC (you may need to install the IPC::Run module) (@INC contains: /sw/lib/perl5/darwin-thread-multi-2level /sw/lib/perl5 /sw/lib/perl5/darwin /Library/Perl/5.18/darwin-thread-multi-2level /Library/Perl/5.18 /Network/Library/Perl/5.18/darwin-thread-multi-2level /Network/Library/Perl/5.18 /Library/Perl/Updates/5.18.4 /System/Library/Perl/5.18/darwin-thread-multi-2level /System/Library/Perl/5.18 /System/Library/Perl/Extras/5.18/darwin-thread-multi-2level /System/Library/Perl/Extras/5.18 .) at /Users/BNW/u/kh/bin/bosswrap.pl line 3.
BEGIN failed--compilation aborted at /Users/BNW/u/kh/bin/bosswrap.pl line 3.

我在做错什么，或者更确切地说，如何使它正常工作?

What am I doing wrong, or rather, how can I get this to work?

推荐答案

尝试以下操作:

sudo perl -MCPAN -e 'install -force Net::ARP'
