Question

我正在尝试向ASP页发出回发请求，所以我安装了WWW :: Mechanize :: Chrome 0.23及其所有必需的模块，并尝试执行该库随附的示例脚本，并出现以下错误：

Can't call method "new" without a package or object reference at C:/Strawberry/perl/vendor/lib/Chrome/DevToolsProtocol/Transport.pm line 42.

这是javascript示例（https://metacpan.org/pod/release/CORION/WWW-Mechanize-Chrome-0.23/lib/WWW/Mechanize/Chrome/Examples.pm#Example:-javascript.pl）的代码：

#!perl -w
use strict;
use WWW::Mechanize::Chrome;

my $mech = WWW::Mechanize::Chrome->new(tab => undef);
$mech->get_local('links.html');

$mech->eval_in_page(<<'JS');
    alert('Hello Frankfurt.pm');
