Selenium GeckoDriver启动Firefox浏览器的速度很慢 [英] Selenium GeckoDriver is slow to launch Firefox Browser

问题描述

我最近一直在尝试建立Selenium环境并重新运行.一切正常，脚本执行正常，使用其他Web驱动程序等.

I have recently been trying to get a Selenium environment up and running again. Everything works as it should with scripts executing as they should, using different web drivers etc etc.

但是，每个驱动程序的初始启动需要2-5分钟才能启动.这使我的脚本开发和故障排除变得很痛苦.

However, the initial launch of each driver takes anywhere between 2-5 min to launch. This makes it a pain to develop and troubleshoot my scripts.

我将Python 3.6与PyCharm和Selenium一起安装在pip上.Python 2.7中存在相同的问题.

I use Python 3.6 with PyCharm and Selenium installed with pip. The same issue is present with Python 2.7.

到目前为止，我已经尝试过的事情(没有成功):

Things I have tried so far (without success):

• 重新安装Python
• 重新安装硒
• 通过PyCharm和终端运行脚本
• 用早期和更高版本替换了网络驱动程序.
• 已禁用网络驱动程序的代理和javascript

这是我正在跑步的东西.这个简单的脚本最多需要5分钟才能运行，但可以正常运行，并且不返回任何警告或错误.

Here is what I am running. This simple script takes up to 5min to run, but works correctly and returns no warnings or errors.

from selenium import webdriver
import time
print(time.localtime())
browser = webdriver.Firefox()
browser.get('http://seleniumhq.org/')
print(time.localtime())

上面的代码仅运行一次即可产生以下geckodriver.log

A single run of the code above yields the following geckodriver.log

您的主要问题是系统中存在杂务.

Your main issue is the presence of os chores within your system.

• 您的 Selenium Client 版本对我们未知.
• 您的 GeckoDriver 版本是 v0.19.1 .
• 您的 Firefox 版本对我们来说是未知.

• Your Selenium Client version is unknown to us.
• Your GeckoDriver version is v0.19.1.
• Your Firefox version is unknown to us.

要加快操作速度，请按以下步骤操作:

To speed up the operation follow the steps:

• 将硒升级到当前级别 版本3.12.0 > .
• 将 GeckoDriver 升级到 GeckoDriver v0.20.1 级.
• 确保在指定位置存在 GeckoDriver 二进制文件.
• 确保 GeckoDriver 具有非root用户的可执行权限.
• 将 Firefox 版本升级到 Firefox v60.0.1 级别.
通过 IDE
• 清理您的项目工作区和重建您的项目，并且仅具有必需的依赖项.
• 使用 CCleaner 工具清除之前和之后的所有操作系统杂项在您执行 Test Suite 之后.
• 如果您的基本 Web客户端版本太旧，请通过来卸载. Revo Uninstaller 并安装最新版本的 Web客户端 GA和发行版.
• 进行系统重启.
• 以非root用户身份执行 Test .
• 始终在 tearDown(){} 方法中调用 driver.quit()以关闭&优雅地销毁 WebDriver 和 Web Client 实例.

• Upgrade Selenium to current levels Version 3.12.0.
• Upgrade GeckoDriver to GeckoDriver v0.20.1 level.
• Ensure GeckoDriver binary is present in the specified location.
• Ensure GeckoDriver is having executable permission for non-root users.
• Upgrade Firefox version to Firefox v60.0.1 levels.
• Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
• Use CCleaner tool to wipe off all the OS chores before and after the execution of your Test Suite.
• If your base Web Client version is too old, then uninstall it through Revo Uninstaller and install a recent GA and released version of Web Client.
• Take a System Reboot.
• Execute your Test as a non-root user.
• Always invoke driver.quit() within tearDown(){} method to close & destroy the WebDriver and Web Client instances gracefully.

注意:请勿禁用 JavaScript .禁用 JavaScript 可能会导致网页加载不完整，因为所有Web设计人员/开发人员都认为 JavaScript 在每种浏览器中都可用，并且所有最近的浏览器功能和效果都使用 JavaScript .

Note: Do not disable JavaScript. Disabling JavaScript might lead to a incomplete loading of the webpage as all the web designers/developers believes JavaScript is available in every browser and all the recent browser features and effects are implemented using JavaScript.
