[問題] perl 如何建立 excel workbook

[gecer (gecer)]

小弟我試寫了下列一段code

use strict;
use warnings;
use Excel::Writer::XLSX;

my $path="D:\cell_b.xlsx";

my $workbook  = Excel::Writer::XLSX->new($path);
my $worksheet = $workbook->add_worksheet("New_Sheet");

$worksheet->write(0,0,"haha");



my $workbook  = Excel::Writer::XLSX->new($path); 這一行無法執行

但是若改成  my $path="cell_b.xlsx";  卻可以  請問perl excel module
無法指定新workbook的路徑嗎?

推 MistQ: "D:\\cell_b.xlsx" or 'D:\cell_b.xlsx'
請教"" 和''這兩者在perl有什麼差異?
