使用Python Splinter库时出错

Question

我刚刚在beaglebone机器上安装了Splinter python库。当我使用split网站上提供的例子时，我得到了一个错误。我相信我需要安装一个网络驱动程序才能工作。

有人在beaglebone arm7平台的命令行上安装了任何网络驱动程序吗？

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

Answer 1

可能有点太晚了，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Firefox

或

• 下载Chromedriver，以便硒（碎片）浏览谷歌Chrome。有关设置Chromedriver的更多信息，请参阅本讨论

希望它能有所帮助！

Answer 2

我不确定（我只在实际的桌面上运行过split），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。它一定在努力做到这一点。自从你提出这个问题以来，你解决了这个问题吗？
