missing package or object reference

joeorozco316 has asked for the wisdom of the Perl Monks concerning the following question:

I just installed Text::CSV, my code is below, and here is my error:
Can't call method "getline" without a package or object reference at C:/Perl/site/lib/Text/CSV_XS.pm line 555, <FILE> line 2.
This might seem trivial, but I can't find the answer when I google my error.
I have also tried, use Text::CSV & Text::CSV->new and still had the same error.

#!C:\Perl\bin\perl

use warnings;
use strict;
use Text::CSV_XS;

my $file = "file.csv";

open FILE, $file or die "cannot open file\n";
my $first = <FILE>;
my @columns = split(",", $first);

my $csv = Text::CSV_XS->new ( { binary => 1 } ) or die "Cannot use CSV
+: ".Text::CSV->error_diag ();
$csv->column_names(@columns);

my $lineNum = 1;
while (my $line = <FILE>) {
    
    my $hr = $csv->getline_hr($line);
    my $sku = $hr->{ 'sku' };
    print "$sku\n";
    $lineNum++;
}
close FILE

I think you meant: `... my $lineNum = 1; while ( my $hr = $csv->getline_hr(*FILE) ) { my $sku = $hr->{ 'sku' }; print "$sku\n"; $lineNum++; }` [download] The `getline_hr()` method - just as the underlying `getline()` - expects an IO object (Perl file handle), not a string. To parse lines directly from strings, you'd say `$csv->parse($line)` — but there's no `parse_hr()` method (you don't need it for what you're doing, as the above should work fine). (When using `$csv->getline_hr($line)`, I do get the exact same error.)	[reply] [d/l] [select]

Eliya++ I independently came to the same solution after reviewing this node, and confirm that it works. "Battle not with trolls, lest ye become a troll; and if you gaze into the Internet, the Internet gazes also into you." -Friedrich Nietzsche: A Dynamic Translation	[reply]

How did you install it? Which version? Did you run the test suite , and what were the results?	[reply]

I installed it using Active State PPM. It looks like I have version 1.21. I did not use test suite.	[reply]

Note: Text::CSV and Text::CSV_XS are different modules by different authors. Sure you installed the correct one? Also, a few XS modules wont correctly work when instaklled with PPM. Try this on the command line: `perl -MCPAN -e shell install Text::CSV_XS` [download] Answer all the install (temporary) this or that questions with yes. Post any errors you encounter.
