I have problems when using requests-html package on Python 3.6.5, Ubuntu 16.04(x64). To be more specific, the last line of
from requests_html import HTMLSession
session = HTMLSession()
r = session.get('http://python-requests.org/')
r.html.render()
produces the following error:
Traceback (most recent call last): File "", line 1, in

However, the same code works well without errors on another Windows 10 platform, with the same Python requirements configured.
I have checked whether a Chrome has been downloaded successfully on my computer and the result is yes! So I think that's not where the problem is.

I have already searched the guidebook of requests-html for answers but got nothing found. I want the command r.html.render() to work correctly, what can I do now?
