【问题标题】:Error using Python Splinter Library使用 Python 分裂库时出错
【发布时间】:2013-07-24 01:16:07
【问题描述】:

我刚刚在我的 beaglebone 机器上安装了 Splinter python 库。 当我使用 splinter 网站上提供的示例时,出现错误。 我相信我需要安装一个网络驱动程序才能工作。

是否有人在 beaglebone arm7 平台的命令行上安装了任何 Web 驱动程序?

未修改的代码

from splinter import Browser

 with Browser() as browser:
     # Visit URL
     url = "http://www.google.com"
     browser.visit(url)
     browser.fill('q', 'splinter - python acceptance testing for web applications')
     # Find and click the 'search' button
     button = browser.find_by_name('btnG')
     # Interact with elements
     button.click()
     if browser.is_text_present('splinter.cobrateam.info'):
         print "Yes, the official website was found!"
     else:
         print "No, it wasn't found... We need to improve our SEO techniques" 

错误是

    【解决方案1】:

    可能有点晚了,但以防万一:

    我遇到了同样的问题,因为我没有安装 Firefox。 Splinter 基于 selenium,它使用 Mozilla Firefox 作为默认浏览器,因此:

    • 安装火狐

    • 下载 Chromedriver 以便 selenium (splinter) 浏览 Google Chrome。有关设置 Chromedriver 的更多信息,请参阅此discussion

    希望对你有帮助!

      【解决方案2】:

      我不确定(我只在实际桌面上运行过 splinter),但我认为问题只是缺少指定的显示。当您在桌面上运行默认代码时,它会打开一个 Web 浏览器窗口。它必须在这里尝试相同。 自从您提出问题后,您解决了问题吗?
