python - selenium python 无法与 phantomjs 一起使用

Question

我已经通过 python 使用 npm 和 selenium-python 安装了 phantomjs。

Headless Firefox 一切正常，但 phantomjs 则不行。

这是代码。

In [1]: from selenium import webdriver

In [2]: browser = webdriver.PhantomJS()

In [3]: browser.get('http://www.google.com/')

有什么解决办法吗？

确保您至少使用 PhantomJS 1.8，直到该版本他们才支持 webdriver 连接。我知道昨天我经历这个的时候我的包管理器有一个更旧的版本。 http://phantomjs.org/release-1.8.html
