ImportError: Нет модуля с именем '_struct' при установке setuptools

Я бы сделал это в perl, потому что мне кажется, что так понятнее:

#!/usr/#bin/env perl
use strict;
use warnings;
use Data::Dumper;


my ( $pattern_file_name, $process_file_name ) = @ARGV; 

open ( my $patterns_file, '<', $pattern_file_name ) or die $!;
my @matches = map { [split] } <$patterns_file>;
close ( $patterns_file );

print "Using:\n";
print Dumper \@matches;

#my @matches = ( [ '311', '2222' ], [ '833', '7777' ], [ 'Jam', '33333' ] );

#read main file
my @results;
open  ( my $input, '<', $process_file_name ) or die $!; 

#iterate a line at a time. 
while ( my $line = <$input> ) {
 GROUP:
   for my $id ( 0 .. $#matches ) {
      #Check each set of expressions.
      foreach my $expression ( @{ $matches[$id] } ) { 
         #move to the next group if any don't match
         next GROUP unless $line =~ m/$expression/;
      }
      #didn't get skipped, so must have matched all. 
      push( @{ $results[$id] }, $line );
   }
}
print Dumper \@results;

print "\n$_\n" for @results;
close ( $input );
