我是新手使用PDL并在Ubuntu下安装后（在英特尔®酷睿™i7-3630QM CPU上运行12.04 LTS @ 2.40GHz×8作为Windows 8.1双启动）
我尝试了First Steps with PDL上给出的第一个示例，但收到有关PDL::Graphics::Simple的错误消息，如下所示。我猜它可能很简单？
$ pdl
perlDL shell v1.357
...
Loaded PDL v2.007
Note: AutoLoader not enabled ('use PDL::AutoLoader' recommended)
pdl> use PDL::Graphics::Simple
但收到错误消息：
Can't locate PDL/Graphics/Simple.pm in @INC (@INC contains: /etc/perl /usr/local/lib/perl/5.14.2 /usr/local/share/perl/5.14.2 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.14 /usr/share/perl/5.14 /usr/local/lib/site_perl .) at (eval 70) line 5.
