You have several errors.
You must read the file (not just open it). Use <$fh>.
You must slurp the entire file (not just read the first record). Use undef $/.
You must not declare %hash1 as a lexical variable within the eval. (The eval string is treated as a block)
Under strict, you must declare %hash1 in your program.
#tiny.pl
#!/home/utils/perl5/perlbrew/perls/5.24.2-021/bin/perl
use strict;
use warnings;
use Path::Tiny qw( path );
use Data::Dumper;
#my $file = 'file.pl';
my $file = \<<'file_end'; # Simulate disc file for post
%hash1 = (hello => 1,
hi =>2 );
file_end
my %hash1;
open(my $fh, '<', $file) or die "Could not open file $file";
local undef $/;
eval( <$fh> );
close $fh;
print Dumper(\%hash1);
>perl tiny.pl
$VAR1 = {
'hi' => 2,
'hello' => 1
};

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
