Python + Splinter: Error - httplib.BadStatusLine: ''

Question

In my python project, I'm using Splinter (https://splinter.readthedocs.io/en/latest/) to open a browser and attempt visit a site:

from splinter import Browser

browser = Browser('chrome')
browser.visit('http://www.google.com')

And the browser opened up, and without being able to visit http://www.google.com, it got the following error:

Weirdly, it works on a different Mac computer, but when I transferred it to another Mac computer, encountered that error.

Researched around but could not make out what the real problem is. What could I be doing wrong? And how should I go about resolving the issue?

Thank you in advance and will be sure to upvote/accept answer

Have you verified the chromedriver version on the Mac computer where it failing? – Monecious

@Monecious How can I do so? And what should I be looking for? – Misbegotten

Answer 1

The symptoms you are describing point to the outdated chromedriver. Go to the "ChromeDriver Downloads" page and download the latest driver. For the currently latest stable Chrome 58, you need chromedriver 2.29.

Note that to check the chromedriver version, execute:

$ chromedriver --version

And, also, make sure you have the latest splinter and selenium:

$ pip install -U splinter selenium

Appreciate your response. Is there a way to install the latest chromedriver via terminal? Because if I do it manually, there seem to be an issue with setting up the path. – Misbegotten

@JoKo have not tried that, but it looks like there is this option. Thanks. – Vitriol

still having trouble. I checked the chromedriver version and it was 2.22. Tried installing and it keeps saying I have chromedriver 2.22, and updated both splinter/selenium as suggested yet still getting the same error... – Misbegotten
