在自己的ubuntu 16.04安装了perl6，想玩一把。
一般ubuntu主机都自带了perl5。
在终端输入perl –version，打印如下：
This is perl 5, version 22, subversion 1 (v5.22.1) built for x86_64-linux-gnu-thread-multi
(with 58 registered patches, see perl -V for more detail)

其实安装perl6之后perl5和perl6是可以共存的。
官网：https://www.perl6.org/ 中安装说明如下：
% wget https://rakudo.perl6.org/downloads/star/rakudo-star-2017.01.tar.gz
% tar xfz rakudo-star-2017.01.tar.gz
% cd rakudo-star-2017.01
# perl Configure.pl --gen-moar --prefix /opt/rakudo-star-2017.01
# make install
然后注意把perl6加入命令中，做法如下：
在终端输入 vi ~/.bashrc 编辑该文件：
输入：
alias perl6="cd /home/soft_file/rakudo && ./perl6"
这里你把/home/soft_file/rakudo换成你的perl6包解压目录即可。
然后source ~/.bashrc使环境变量生效。
再次在终端输入perl6 –version，打印结果如下：
This is Rakudo version 2017.01 built on MoarVM version 2017.01
implementing Perl 6.c.
说明perl6安装配置成功。
