Why does Perl's URI complain "Can't locate object method "host" via package "URI::_generic"'?

With these it helps URI->new creates instances of a subclass of URI, depending on the scheme of the url you give it. Those subclasses might be URI::http, URI::file, URI::mailto, or something completely different. If URI doesn't have a specialized subclass for the kind of url you gave it, it'll create an instance of URI::_generic. Each of those URI subclasses have different methods. URI::http happens to have a host method, but most others don't. You're calling ->host on something that isn't a URI::http or similar, and therefore doesn't have a host method.

Perl can't locate object method "query_form" via package "URI::_foreign" at Geo::Coder::Google::V3.p

should help you out The URI constructor creates an object instance specific to the scheme of the data passed to it. For http data, that is URI::http. However, if it's unable to determine a scheme, the final fall back is of class URI::_foreign. Each of these subclasses have different abilities and features. As you've observed, the base class _foreign does not have an implementation of query_form. use strict;
use warnings;
use URI;
while (<DATA>) {
chomp;
my $u = URI->new($_);
printf "%-13s - %s\n", ref($u), $u;
}

Perl 'can't locate object method "worksheets" via package "Spreadsheet::ParseExcel::Workbook"'

fixed the issue. Will look into that further The workbooks() method was added in 0.43, six years ago. Since your version of Perl is rather old (11 years), it's likely your version of Spreadsheet::ParseExcel is also rather old. You can check with: perl -MSpreadsheet::ParseExcel -wle 'print $Spreadsheet::ParseExcel::VERSION'

Error restoring from nstore_fd: Can't locate object method "FIRSTKEY" via package "Hash::Case::Lower"
Date : March 29 2020, 07:55 AM
I wish this helpful for you When you restore objects that are tied to packages, you first need to load their classes. Storable as well as, for example, Sereal will not load them for you. It recreates the objects as they are stored, and Perl expects the packages to exist. All you need to do is load the module before deserializing your backup. use Storable qw(fd_retrieve);
use Hash::Case::Lower;
my $data = fd_retrieve(*STDIN); # the backup file
