英文:
Perl/cpan: Can't locate JSON/Parse.pm @INC
问题
我正在运行 CentOS 7。
我已经通过 cpan 安装了 JSON::Parse,但出现了错误。
无法在 @INC 中定位 JSON/Parse.pm (@INC 包含:
/home/truckassist/modules
/usr/local/lib64/perl5
/usr/local/share/perl5
/usr/lib64/perl5/vendor_perl
/usr/share/perl5/vendor_perl
/usr/lib64/perl5
/usr/share/perl5 .)
当运行 cpan JSON::Parse
时,我得到了以下结果:JSON::Parse 已经是最新版本 (0.62)
到目前为止,我尝试了以下方法...
perl -e "print qq(@INC)"
输出:
/root/perl5/lib/perl5/5.16.3
/root/perl5/lib/perl5/x86_64-linux-thread-multi
/root/perl5/lib/perl5
/usr/local/lib64/perl5
/usr/local/share/perl5
/usr/lib64/perl5/vendor_perl
/usr/share/perl5/vendor_perl
/usr/lib64/perl5
/usr/share/perl5
还有:
find /root/perl5 -iname '*json*'
输出:
/root/perl5/bin/json_pp
/root/perl5/bin/validjson

/root/perl5/man/man3/JSON::MaybeXS.3pm
/root/perl5/man/man3/JSON::Tokenize.3pm
/root/perl5/man/man3/JSON::Whitespace.3pm
我只能假设它正在查看错误的 cpan/perl 目录。
是否有人可以协助或提供一些方向?

I'm running on CentOS 7.
I've installed JSON::Parse via cpan but getting the error.
Can't locate JSON/Parse.pm in @INC (@INC contains:

When running cpan JSON::Parse
I get the following: JSON::Parse is up to date (0.62)
I've tried the following so far...
perl -e "print qq(@INC)"

I can only assume it's looking at the incorrect cpan/perl directory.
Can anyone please assist or provide some direction?

你将模块安装在非标准目录 (/root/perl5/lib/perl5/x86_64-linux-thread-multi
),[1] 且你没有告诉 perl
关于它的存在[2],或者你没有足够的权限来访问它。
确保其他用户具备访问 /root/perl5
及其内容所需的权限。
要通知 perl
在哪里查找这些模块,你可以使用
export PERL5LIB=/root/perl5/lib/perl5
或者,停止在安装给机器上的所有人时将模块安装在不寻常的位置。
在以 root 身份时取消设置 PERL_MB_OPT
和 PERL_MM_OPT
(以及 PERL5LIB
),然后重新安装该模块。你可能想要摆脱 /root/perl5
以避免混淆。
- 你作为 root 使用 local::lib,为 root 安装模块 "仅限 root"。
- 除非以 root 身份运行,这就是为什么
cpan
在以 root 身份运行时找到它的原因。 - 例如,不要在以 root 身份时使用 local::lib。
英文:
You installed the module in a non-standard directory (/root/perl5/lib/perl5/x86_64-linux-thread-multi
),<sup>[1]</sup> and you didn't tell perl
about it<sup>[2]</sup>, or you don't have sufficient permissions to access it.
Make sure other users have the permissions needed to access /root/perl5
and its contents.
And to let perl
know where the find the modules, you could use
export PERL5LIB=/root/perl5/lib/perl5
Alternatively, stop installing the module in an unusual location when installing for everyone on the machine.
Unset PERL_MB_OPT
and PERL_MM_OPT
(and PERL5LIB
) when root,<sup>[3]</sup> then re-install the module. You might want to get rid of /root/perl5
to avoid confusion.
- You are using local::lib as root, installing modules "just for root".
- Except when running as root, which is why
cpan
finds it when root. - For example, by not using local::lib as root.
