系统版本：ubuntu16.04LTS

软件安装提示：
Here are the steps to install and run it:

make sure perl and cpan are installed.
Install perl packages by
cpan AnyEvent::HTTP Data::Dumper JSON

于是，我在终端下切换到root权限后使用命令



进行安装，安装过程提示：

当时我也没细看，即开始执行



却出现错误如下：

Can't locate AnyEvent/HTTP.pm in @INC (you may need to install the AnyEvent::HTTP 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 .) at iotScanner.pl line 1.
BEGIN failed--compilation aborted at iotScanner.pl line 1.

不知道怎么解决这个错误，请教！！！

当时没仔细看，现在可以仔细看了吧？

现在仔细看了还是不知道咋办
