工作需要开始学Perl,下载个Window版(5.16)的: 下载链接
http://www.activestate.com/activeperl/downloads
安装好了之后，写第一个perl程序
复制代码 代码如下:
#!/usr/bin/perl
print \”Hello,World!\\n\”;
运行结果: (很像Python哦)
复制代码 代码如下:
c:\\Perl>perl HelloWorld.pl
Hello,World!
接着学了下:cpan,虽然不知道这家伙具体是干嘛，应该是能安装各种包，9000多种。
命令如下：看第二次输出的结果，应该是类似于数据库的东东吧。
复制代码 代码如下:
c:\\Perl>cpan App::cpanminus
Set up gcc environment – 3.4.5 (mingw-vista special r3)
CPAN: Term::ANSIColor loaded ok (v4.02)
CPAN: Storable loaded ok (v2.34)
Reading \’C:\\Perl\\cpan\\Metadata\’
Database was generated on Fri, 07 Mar 2014 13:06:13 GMT
CPAN: Module::CoreList loaded ok (v2.80)
App::cpanminus is up to date (1.7001).
然后用cpanm安装模块，命令如下: (cpanm Module::Name)
复制代码 代码如下:
c:\\Perl>cpanm YAML
Set up gcc environment – 3.4.5 (mingw-vista special r3)
–> Working on YAML
Fetching http://www.cpan.org/authors/id/I/IN/INGY/YAML-0.90.tar.gz … OK
Configuring YAML-0.90 … OK
Building and testing YAML-0.90 … OK
Successfully installed YAML-0.90
1 distribution installed
如果实在不晓得如何用的话: cpanm –help //–>会看到很多提示。
复制代码 代码如下:
c:\\Perl>cpanm –help
Set up gcc environment – 3.4.5 (mingw-vista special r3)
Usage: cpanm [options] Module […]
Options:
-v,–verbose Turns on chatty output
-q,–quiet Turns off the most output
看上面的安装过程，好像是可以执行cpanm Link,果然是可以:
复制代码 代码如下:
c:\\Perl>cpanm http://search.cpan.org/CPAN/authors/id/S/SH/SHARYANTO/Alt-Base-0.0
2.tar.gz
Set up gcc environment – 3.4.5 (mingw-vista special r3)

Building and testing Alt-0.04 … OK
Successfully installed Alt-0.04
Building and testing Alt-Base-0.02 … OK
Successfully installed Alt-Base-0.02
2 distributions installed
然后开始写了个文件操作的脚本，里面有个Path::Class模块。
复制代码 代码如下:
use Path::Class;
C:\\Perl\\Learn>perl FindFile.pl
Can\’t locate Path/Class.pm in @INC (@INC contains: C:/Perl/site/lib/MSWin32-x86-
multi-thread C:/Perl/site/lib C:/Perl/lib .) at FindFile.pl line 4.
BEGIN failed–compilation aborted at FindFile.pl line 4.
看提示，像没有安装该包，安装了下该包，结果果然没报这种错误:
复制代码 代码如下:
C:\\Perl\\Learn>cpanm Path::Class
Set up gcc environment – 3.4.5 (mingw-vista special r3)
–> Working on Path::Class
Fetching http://www.cpan.org/authors/id/K/KW/KWILLIAMS/Path-Class-0.33.tar.gz ..
. OK

Successfully installed Path-Class-0.33

完~
