无法在RHEL 7.6中将Perl 5.8升级到5.16

Question

6无法从5.8.9升级我的机器。当我使用yum安装时，它说安装成功，但当我检查版本时，它仍然是旧版本。我需要的版本是5.10或以上。详情如下：

bash$ cat /etc/*release
NAME="Red Hat Enterprise Linux Server"
VERSION="7.6 (Maipo)"
bash$ 
bash$ yum info perl
Name        : perl
Arch        : x86_64
Epoch       : 4
Version     : 5.16.3
Release     : 294.el7_6
Size        : 22 M
Repo        : installed
From repo   : rhel-7-server-rpms
Summary     : Practical Extraction and Report Language
URL         : http://www.perl.org/
bash$ perl -v

This is perl, v5.8.9 built for x86_64-linux-thread-multi
(with 1 registered patch, see perl -V for more detail)

bash$ whereis perl

解决方案：

bash$ whereis perl5.16.3
perl5.16: /usr/bin/perl5.16.3
bash$ ll | grep -i perl
lrwxrwxrwx.  1 root root   19 Jul  2  2019 perl -> /usr/ravi/bin/perl
bash$ sudo ln -s -f /usr/bin/perl5.16.3 perl
bash$ 
bash$ ll | grep -i perl
lrwxrwxrwx   1 root root   19 Feb 22 17:49 perl -> /usr/bin/perl5.16.3
bash$ perl --version
perl -v

This is perl 5, version 16, subversion 3 (v5.16.3) built for x86_64-linux-thread-multi
