python - 使用 Python Splinter 库时出错

Question

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。我相信我需要安装网络驱动程序才能正常工作。

有人在命​​令行上为 beaglebone arm7 平台安装过任何 Web 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"

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:

• 安装火狐浏览器

或

• 下载 Chromedriver，以便 selenium (splinter) 可以通过 Google Chrome 浏览。看这个discussion有关设置 Chromedriver 的更多信息

希望对你有帮助!
