cpan命令给出错误“无法在@INC中找到B.pm”。 [英] cpan command gives the error "Can't locate B.pm in @INC"

问题描述

我想使用CPAN安装一些Perl软件包，但是当我尝试启动CPAN shell时出现以下错误：

  paulzierep @ naproxen：〜$ cpan 
在@INC中找不到B.pm（您可能需要安装B模块）（@ INC包含：/ etc / perl /usr/local/lib/x86_64-linux-gnu/perl/5.22.1 /usr/local/share/perl/5.22.1 /usr/lib/x86_64-linux-gnu/perl5/5.22 / usr / share / perl5 /usr/lib/x86_64-linux-gnu/perl/5.22 /usr/share/perl/5.22 / usr / local / lib / site_perl / usr / lib / x86_64-linux-gnu / perl-base / home / paulzierep） /usr/share/perl/5.22/Safe.pm第34行。

编译在/ usr / bin / cpan第9行的require中失败。
 BEGIN失败-在/ usr / bin / cpan第9行的编译中止。
  

我不知道如何在没有cpan的情况下安装缺少的B模块。我猜应该默认安装。

我在Ubuntu 16.04上使用Perl 5.22.1。

更新

所以我将 PERL5LIB 或 PERL5OPT 设置为找到 / usr /lib/x86_64-linux-gnu/perl/5.22.1/B.pm ，并且CPAN运行，但是由于以下错误，我无法安装任何软件

所以它解决了问题，给我带来了另一个问题。对这个有什么帮助吗？

那是我得到的：

解决方案

我遇到了同样的问题。由于某些未知原因，目录 / usr / lib / x86_64-linux-gnu / perl 为空。我的解决方案是重新安装 libperl5.22 软件包。

  sudo apt -get install --reinstall libperl5.22 
  

I wanted to use CPAN to install some Perl packages, but I get the following error when I try to start the CPAN shell:

paulzierep@naproxen:~$ cpan
Can't locate B.pm in @INC (you may need to install the B module) (@INC contains: /etc/perl /usr/local/lib/x86_64-linux-gnu/perl/5.22.1 /usr/local/share/perl/5.22.1 /usr/lib/x86_64-linux-gnu/perl5/5.22 /usr/share/perl5 /usr/lib/x86_64-linux-gnu/perl/5.22 /usr/share/perl/5.22 /usr/local/lib/site_perl /usr/lib/x86_64-linux-gnu/perl-base /home/paulzierep) at /usr/share/perl/5.22/Safe.pm line 34.

Compilation failed in require at /usr/bin/cpan line 9.
BEGIN failed--compilation aborted at /usr/bin/cpan line 9.

I can't figure out how to install the missing B module without cpan. I guess this should be installed by default.

I'm using Perl 5.22.1 on Ubuntu 16.04.

Update

So I set the PERL5LIB or PERL5OPT to make it find /usr/lib/x86_64-linux-gnu/perl/5.22.1/B.pm, and CPAN runs, but I can not install anything due to the following error

cpan[1]> install Log::Log4perl

Failed during this command:

So it kind of fixed it and left me with another problem. Any help on this one?

That what I get for:

paulzierep@naproxen:~$ perl -E 'say for @INC'
/etc/perl
/usr/local/lib/x86_64-linux-gnu/perl/5.22.1
/usr/local/share/perl/5.22.1

/usr/share/perl/5.22
/usr/local/lib/site_perl
/usr/lib/x86_64-linux-gnu/perl-base
.

/usr/local/bin

解决方案

I had the same problem. For some unknown reason, the directory /usr/lib/x86_64-linux-gnu/perl was empty. My solution was to reinstall the libperl5.22 package.

sudo apt-get install --reinstall libperl5.22
