可能有用我的第一个健康检查是总是尝试启动chromium，并确保在试用selenium之前它不会给我带来首次使用的麻烦。那里一切都好吗？@kiminoa如何自己检查铬？我试图直接运行chromium浏览器，但出现两个错误：无法加载libexif和Gtk:无法打开display@PadraicCunningham我试着关注这篇博文，但它没有改变任何事情。我不知道这是否重要，但我在Ubuntu服务器上，所以没有显示。这可能与此有关？谢谢你的回复。您知道使用一种解决方案与使用另一种解决方案在性能/简单性/开销方面是否有很大差异吗？@YAmikep我想这将取决于您的具体案例度量：）谢谢。对不起，我尝试了PhantomJS选项，虽然我仍然需要弄清楚如何在大量使用ajax请求的网站上很好地使用它，但它似乎仍然有效。感谢您的帮助。chromedriver似乎在selenium客户端请求时启动了浏览器，但由于DISPLAY环境变量未指向X服务器，浏览器死机。如果在X会话的终端窗口中启动chromedriver，我会在启动chromedriver之前运行“echo$DISPLAY”，以确保它包含诸如“：0”之类的字符串。此外，我还认为chromedriver会使用以下逻辑猜测浏览器的位置：如果目录项“chrome”存在于包含chromedriver的同一目录中，执行该条目。当我将chromedriver放在/opt/google中并将浏览器放在/opt/google/chrome/中时，这个逻辑甚至无法启动浏览器。为了解决这个问题，我将chromedriver移动到/opt/google/chrome/。
