我正在试图按here解释子类MIME::Parser::FileUnder。所以我安装该模块:CPAN安装模块说OK,但编译在该模块上失败

$ sudo cpan install MIME::Parser::FileUnder 
[...] 
Result: PASS 
    DSKOLL/MIME-tools-5.504.tar.gz 
    /usr/bin/make test -- OK 
Running make install 
Manifying blib/man3/MIME::Decoder::Gzip64.3pm

    DSKOLL/MIME-tools-5.504.tar.gz 
    sudo /usr/bin/make install -- OK 

貌似正确安装,但

$ ./test_gmail.pl 
Can't locate MIME/Parser/FileUnder.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 GMailMIMEParser.pm line 4. 
BEGIN failed--compilation aborted at GMailMIMEParser.pm line 4. 
Compilation failed in require at ./test_gmail.pl line 13. 
BEGIN failed--compilation aborted at ./test_gmail.pl line 13. 

如果我尝试重新安装MIME::Parser::FileUnder,它会奇怪,而不是安装它告诉我的是最新的像任何其他模块。

这是我的子类GMailMIMEParser

package GMailMIMEParser; 

use strict; 
use MIME::Parser::FileUnder; 

our @ISA = qw(MIME::Parser::FileUnder); 

my $cur = 0; 

sub output_path 
{ 
    my $class = shift; 
    my $head = shift; 
    print(STDERR $head); 
    $cur++; 
    return "./$cur"; 
} 

提前感谢!

这是一个文件管理器子类或MIME解析器,所以我想你想的东西就像我的$解析器=新的MIME ::分析器;,然后$ parser-> filer-> output_path(XXX)。 – Analog 2013-03-23 16:53:37

我不明白你的意思。我必须继承'MIME :: Parser :: FileUnder',如链接中所述,使用我自己的'output_path()'。 'GMailMIMEParser'子类'MIME :: Parser :: FileUnder',但它不会识别'MIME :: Parser :: FileUnder' – m0skit0 2013-03-23 17:14:54

我只是在做错误的事情。我必须子类MIME::Parser::Filer而不是MIME::Parser::FileUnder,这本身就是MIME::Parser::Filer子类。

package GMailMIMEParser; 

use strict; 
use MIME::Parser::Filer; 

our @ISA = qw(MIME::Parser::Filer); 

my $cur = 0; 

sub output_path 
{ 
    my $class = shift; 
    my $head = shift; 
    print(STDERR $head); 
    $cur++; 
    return "./$cur"; 
}
