I can't run the script with the message: Driver info: driver.version: unknown

Most likely you need to configure your SUID sandbox correctly

Answer 1

I believe your chrome and driver is not compatible.
The easy way is to install it using package manager.
# yum -y install epel-release chromium chromedriver
# java -Dwebdriver.chrome.driver=/usr/bin/chromedriver -jar [ your selenium standalone jar path ]
I'm assuming you got the reference code from https://www.perl.com/article/spidering-websites-with-headless-chrome-and-selenium/
It's spesific to https://example.com
Below codes work for me:
my $driver = Selenium::Remote::Driver->new(
browser_name => 'chrome',
extra_capabilities => { chromeOptions => {args => [
'window-size=1920,1080',
'headless',
'no-sandbox',
]}},
);
my %visited = ();
my $depth = 1;
my $url = 'https://example.com';
spider_site($driver, $url, $depth);
$driver->quit();
sub spider_site {
my ($driver, $url, $depth) = #_;
warn "fetching $url\n";
$driver->get($url);
warn "survive get url\n";
$visited{$url}++;
my $text = $driver->get_title;
warn "survive get title\n";
print encode('UTF-8', $text);
if ($depth > 0) {
warn "finding element\n";
my #links = $driver->find_elements('a', 'tag_name');
my #urls = ();
for my $l (#links) {
warn "link: $l\n";
my $link_url = eval { $l->get_attribute('href') };
push #urls, $link_url if $link_url;
}
for my $u (#urls) {
warn "calling spider_site for url $u";
spider_site($driver, $u, $depth - 1) unless ($visited{$u});
}
}
}
