python，selenium，chr​​omedriver 'selenium.common.exceptions.WebDriverException：消息：u'chrome 无法访问

Question

我正在使用此代码导航网页，使用 selenium 和 chromedriver 2.9（也尝试过 2.8 但没有成功）...我收到此错误，我想要的只是测试显示在 firefox iframe 中:)

firefox 支持 iframe 中的图片链接没有问题，而且图片弹出效果很好。但是文本不会显示在 iframe 中。不知道为什么图片链接有效，但文字无效。

以下是从 python 脚本生成的错误消息。该脚本试图通过检查点，但随后会产生错误。我完全迷路了。

我从您的代码中注意到您正在操纵TinyMCE。此编辑器需要由 JavaScript 处理。 SO和Internet上有很多答案如何处理这个问题。这是一个很好的答案：Selenium and wordpress: New post test
