python 中的分裂 chromedriver 崩溃

Question

I am trying to make a python program work on my mac machine, where the splinter library is being used. Unfortunately the program crashes, whenever i attempt to run the program. Author of the program: https://github.com/lrnq/supremeBot

Whenever i attempt to run the program, it quickly opens a browser 3 times, but crashes immediately. The error I receive is:

Traceback (most recent call last):
  File "/Users/yusuf/PycharmProjects/supremeBot/supremeBot/main.py", line 113, in <module>
    BOT.initializeBrowser()
  File "/Users/yusuf/PycharmProjects/supremeBot/supremeBot/main.py", line 25, in initializeBrowser
    self.b = Browser('chrome', **executable_path)
  File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/splinter/browser.py", line 90, in Browser
    return get_driver(driver, *args, **kwargs)
  File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/splinter/browser.py", line 68, in get_driver
    raise e
UnboundLocalError: local variable 'e' referenced before assignment

Any idea why this is happening or how to fix this?

initializeBrowser function where the error occurs:

def initializeBrowser(self):
    driver = self.info["driver"]
    #path = helpers.get_driver_path(driver)

    print(driver)

    if driver == "geckodriver":
        self.b = Browser()
    elif driver == "chromedriver":
        executable_path = {"executable_path": "/usr/local/bin/chromedriver"}
        self.b = Browser('chrome', **executable_path)

I have installed the libraries with following command in terminal:

pip3 install splinter requests bs4

Also, the chromedriver is in the bin folder:

/usr/local/bin/chromedriver

In addition, chomedriver has been added to path:

sudo nano /etc/paths: `/usr/local/bin/chromedriver`

PROGRAM:

#!/usr/bin/env python3
import requests
import bs4 as bs
from splinter import Browser
#import helpers

Answer 1

It looks like splinter has a mistake in their code that results in you not having the correct error message. You could point this out in their issues here . It probably has to do with some problems on their end with going from python2 to python3. This answer explains how this can happen nicely here .

There are a few things you can do to try to solve the problem yourself. I think the problem has to do with your chromedriver not being reached correctly.

1. Make sure your chromedriver and your google chrome browser are the same version. For example, if you have a browser version of 81.xxxx make sure your chromedriver is also of version 81.xxx

2. Put your chromedriver in the same directory as from where your main.py is called

3. Change the line self.b = Browser('chrome', **executable_path) to self.b = Browser('chrome', **executable_path, headless=False)
