使用 Firefox、Geckodriver 和 Perl 運行 Selenium 時出現問題

Question

我在使用 Perl 的 Selenium::Remote::Driver 運行 Selenium 時遇到問題。

我在 Ubuntu 22 上使用 Selenium standalone 3.9.1 + Geckodriver 0.29.0 + Firefox 91.7.0esr

首先，我嘗試使用所有軟件的最新版本，但也出現了錯誤。 在另一台裝有 Centos 7 的機器上，所有這些軟件都運行良好，所以我決定將所有軟件降級到舊版本。

我已經從源代碼安裝了 Firefox，從我的 Centos 7 機器上下載了 Selenium 3.9.1（以確保它沒問題）並下載了 Geckodriver。

我使用此命令運行 Selenium 服務器（geckodriver 在同一文件夾中）：

xvfb-run java  -Dwebdriver.gecko.driver=./geckodriver -jar selenium-server-standalone-3.9.1.jar

服務器正常啟動，但是當我嘗試運行我的 Perl 腳本時 - 它啟動並“凍結”在我創建新的 Selenium::Remote::Driver 對象的字符串處。

這是 Selenium 寫的：

xvfb-run java  -Dwebdriver.gecko.driver=./geckodriver -jar selenium-server-standalone-3.9.1.jar

更新：我的 Perl 腳本的一部分，它凍結在字符串“my $driver = Selenium::Remote::Driver->new;”

#!/usr/bin/perl

use strict;
use warnings;

use utf8;

use DBI;
use Selenium::Remote::Driver;
use Data::Dumper;

binmode STDOUT, ":utf8";

print "Started parser at ".scalar(localtime)."\n\n";

my $dbh = DBI->connect("DBI:mysql:db", "user", "pass", {mysql_enable_utf8 => 1});

my $total_words = 0;

exit if !$ARGV[0];

my @dictionary = @ARGV;

print "Initial hashtag(s): ".join(" ", @dictionary)."\n\n";

my $driver = Selenium::Remote::Driver->new;

$driver->set_window_position(0, 0);
$driver->set_window_size(20000, 600, 'current');

……

更新 2：我已經從源代碼安裝了 Firefox 108，按照@HåkonHægland 的建議下載了 geckodriver 0.32.0 和 selenium 4.7.1。 但它仍然不起作用。

以下是輸出： 這是我嘗試運行 Perl 腳本時的輸出：

Could not create new session: Server returned error message read timeout at /usr/share/perl5/Net/HTTP/Methods.pm line 274.

這是我嘗試運行腳本時 Selenium-server 的輸出：

Answer 1

該解決方案對我來說非常出乎意料 - 我一直在使用 AWS EC2 並且在我增加 CPU 和 RAM 之后 - 一切都開始正常工作！
