Question

您好我想通过cpan安装软件包，但是我收到以下错误：

cpan[1]> install Log::Log4perl

architecture they are running on.
Perl thinks: [5.22.1]

它说要检查我的perl安装，即：

perl --version

此处@INC：

/usr/lib/x86_64-linux-gnu/perl/5.22.1/ /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

我得到的是：

paulzierep@naproxen:~$ perl -E 'say for @INC'

Answer 1

这通常发生在你调用的perl在其他perls留下的库目录中查找时。部分错误是：

您的perl和您的Config.pm似乎对此有不同的看法他们正在运行的架构。

开始在那里调查。找出它找到不匹配的Config.pm的位置并解决该问题。运行perl -V以查看@INC中的内容会有所帮助。

除此之外，您还必须告诉我们有关您的设置的更多信息。

Answer 2

您应该再看看上一个问题的评论

Why does the default cpan on Ubuntu 16.04 give the error "Can't locate B.pm in @INC"?

我发现您的@INC包含 last 位置中的主目录/home/paulzierep

我询问是否设置了环境变量PERL5LIB或PERL5OPT，并且您的唯一回复是

我将PERL5LIB environement var更改为usr / lib / x86_64-linux-gnu / perl / 5.22.1 /实际上我可以打开cpan shell，但我现在尝试安装，我得到：你的perl你的Config.pm似乎对它们运行的架构有不同的看法

我不知道您在@INC末尾获取主目录所做的工作。 PERL5LIB和-I命令行选项都使用unshift而不是push，并将位置添加到@INC的 start } array

默认情况下，很可能在@INC中使用您的主目录构建一个新的perl映像，但如果您已经这样做了，那么您肯定会这样说过吗？

让我明确一点：PERL5LIB和PERL5OPT应该未定义以进行perl的正常操作

Answer 3

您之前曾提到过添加一个您不应添加的PERL5LIB目录。请撤消此更改，此问题将消失。

Answer 4

因此，在删除与perl相关的环境变量后，我回到了之前的错误帖子cpan command gives the error "Can't locate B.pm in @INC"。我设法解决了，所以我认为这也回答了这篇文章。

Perl搞砸了，Cpan无法安装
