这部分可以下载官方的安装包(注意谷歌依赖的安装,这部分很繁琐),也可以进入博主的资源下载。

- google-chrome -version

- # 对应的chromedriver版本查看
- chromedriver -version

版本对应的下载,参考 谷歌chromedriver对应版本下载 文章 或 chromedriver download
下载完成后可以选择设置成环境变量,也可以选择在代码中手动配置chromedriver的路径( /usr/bin/ )。各自选择各自方便的方式即可。

--headless的这一行是要加的。不加--headless谷歌会启动浏览器窗口,如果你的linux不支持可视化则会报错。
- from selenium import webdriver
-
- options = webdriver.ChromeOptions()
- options.add_argument('--headless')
- options.add_argument('--disable-gpu')
- options.add_argument('--no-sandbox')
五、无法从渲染器获取,超时:300.00
selenium.common.exceptions.TimeoutException: Message: timeout: Timed out receiving message from renderer: 10.000
运行环境及版本情况
linux
python :3.6.3
selenium :3.141.0
google-chrome :106.0.5249.103
chromedriver :106.0.5249.61
关于这个报错,网上什么说法都有。大概就以下几点
添加chrome启动参数,如: --disable-gpu
还有讲因为截图(screet-shot)的问题
或是因为google-chrome和chromedriver启动时把cpu占满了,导致无响应。
我的错误奇怪的是它不常出现,属于偶然性情况。不知道哪天就会抛这个异常,很烦,而且我发现一个现象。我的程序只要出现这个异常,然后进程就被停止了。目前因为这个问题难复现,所以也不知道用了网上的方法能不能解决。
