试图使用Log-Log4perl，但该文件是空的（0长度）

Question

我想在我的Perl脚本中使用Log-Log4perl模块。一切正常，但日志记录没有。 这里是我的代码：

sub create_log 
{ 
    BEGIN 
    { 
     eval 
     { 
      require Log::Log4perl; 
     }; 
     if($@) 
     { 
      print "Log::Log4perl module not installed - stubbing.\n"; 
      no strict qw(refs); 
      *{"main::$_"} = sub {} for qw(DEBUG INFO WARN ERROR FATAL); 
     } 
     else 
     { 
      print "Log::Log4perl module installed.\n"; 
      require Log::Log4perl::Level; 
      Log::Log4perl::Level->import(__PACKAGE__); 
      my $conf = q(
       log4perl.category.My.Script = INFO, FileApp, Screen 
       log4perl.appender.FileApp = Log::Log4perl::Appender::File 
       log4perl.appender.FileApp.mode = append 
       log4perl.appender.FileApp.syswrite = 1 
       log4perl.appender.FileApp.filename = my.log 
       log4perl.appender.FileApp.layout = PatternLayout 
       log4perl.appender.FileApp.layout.ConversionPattern = [%p][%d]{%F line %L} %m%n %d> %m%n 
       log4perl.appender.Screen = Log::Log4perl::Appender::Screen 
       log4perl.appender.Screen.stderr = 0 
       log4perl.appender.Screen.layout = Log::Log4perl::Layout::SimpleLayout 
        ); 
      Log::Log4perl->init(\$conf); 
     } 
    } 
} 

create_log(); 
$logger = Log::Log4perl->get_logger("My;:Script"); 
%month_nums = ("Jan" => 1, "Feb" => 2, "Mar" => 3, "Apr" => 4, May => 5, "Jun" => 6, "Jul" => 7, "Aug" => 8, "Sep" => 9, "Oct" => 10, "Nov" => 11, "Dec" => 12); 
$tries = 1; 
$company_fetched = 0; 
$logger->logdie("\n") if !getopts("w:f:", \%options); 
$logger->logdie("Incompatible options.") if $options{'w'} && $options{'f'}; 

当运行脚本，既提供-w和-f我看到这样的屏幕上的错误：

Incompatible options. at /usr/lib/perl5/vendor_perl/5.12.2/Log/Log4perl/Logger.pm line 887 

有什么建议？

看起来像一个错字：

$logger = Log::Log4perl->get_logger("My;:Script"); 

应该

$logger = Log::Log4perl->get_logger("My::Script");
