【问题描述】:
我正在尝试按照here 的解释对MIME::Parser::FileUnder 进行子类化。所以我安装了这个模块:
$ 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
Appending installation info to /usr/local/lib/perl/5.14.2/perllocal.pod
DSKOLL/MIME-tools-5.504.tar.gz
sudo /usr/bin/make install -- OK
看起来安装正确,但是
$ ./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.
如果我再次尝试安装MIME::Parser::FileUnder,它会奇怪地安装它,而不是像任何其他模块一样告诉我它是最新的。
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";
}
提前致谢!
【问题讨论】:
-
这是一个文件管理器子类或 MIME 解析器,所以我想你想要我的 $parser = new MIME::Parser;,然后是 $parser->filer->output_path(xxx)。
-
我不明白你的意思。我必须按照链接中的说明对
MIME::Parser::FileUnder进行子类化,才能使用我自己的output_path()。GMailMIMEParser子类MIME::Parser::FileUnder,但它不会识别MIME::Parser::FileUnder
