在安装模块的过程中，您可以链接到所需的版本。见Makefile.PL：

#============================================================================
# What python are we going to try?
#============================================================================
my @pythons;
my $sep = $^O eq 'MSWin32' ? ";" : ":";
for $p (split /$sep/, $ENV{PATH}) {
    $p =~ s/^~/$ENV{HOME}/;
    $p .= "/python";
    push @pythons, { path => $p } if -f $p && -x $p;
}

# Keep them in PATH order.
#@pythons = sort { $a->{path} cmp $b->{path} } @pythons;

my $num = 1;
print "Found these python executables on your PATH:\n";
print $num++ . ". " . $_->{path} . "\n" for @pythons;

my $sel = prompt("Use which?", '1');
$sel = $pythons[$sel-1] if $sel =~ /^\d+$/;
$sel = { path => $sel } unless ref $sel eq 'HASH';

print "Using $sel->{path}\n";
