Perl Excel::Writer::XLSX

Question

我正在嘗試使用 perl 腳本創建一個 excel 文件。
我按照教程編寫了以下代碼：

#!/usr/bin/perl

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

my $workbook = Excel::Writer::XLSX->new( 'perl.xlsx' );    # Step 1
$worksheet = $workbook->add_worksheet('cc');                   # Step 2
$worksheet->write( 'A1', 'Hi Excel!' );  

但我收到以下錯誤：

Global symbol "$worksheet" requires explicit package name at test_excel.pl line 10.
Global symbol "$worksheet" requires explicit package name at test_excel.pl line 11.

Answer 1

您需要像這樣聲明$worksheet變量

my $worksheet = $workbook->add_worksheet('cc');                   # Step 2
