Question

我刚刚在我的beaglebone机器上安装了Splinter python库。当我使用分裂网站上提供的示例时，我收到错误。我相信我需要安装一个webdriver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，它使用默认浏览器Mozilla Firefox，因此：

安装Firefox

或

下载Chromedriver，以便selenium（splinter）浏览Google Chrome。有关设置Chromedriver

希望它有所帮助！

Answer 2

我不确定（我只在实际桌面上运行了分裂）但我认为问题仅在于缺少指定的显示。在桌面上运行默认代码时，它会打开Web浏览器窗口。它必须在这里尝试相同。既然你问了这个问题，你解决了这个问题吗？
