[splinter chromedriver在python中崩溃

Question

我正在尝试在使用splinter库的mac机上使python程序正常工作。不幸的是，每当我尝试运行该程序时，该程序就会崩溃。该程序的作者：https://github.com/lrnq/supremeBot

[每当我尝试运行该程序时，它都会快速打开浏览器3次，但会立即崩溃。我收到的错误是：

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

知道为什么会这样或如何解决？

发生错误的initializeBrowser函数：

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)

我已经在终端中使用以下命令安装了库：

pip3 install splinter requests bs4

此外，chromedriver位于bin文件夹中：

/usr/local/bin/chromedriver

此外，chomedriver已添加到路径：

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

程序：

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

Answer 1

看起来碎片在他们的代码中有错误，导致您没有正确的错误消息。您可以在他们的问题here中指出这一点。从python2到python3，这可能与它们的某些问题有关。该答案说明了如何很好地进行here。

您可以采取一些措施来尝试自己解决问题。我认为问题与您的chromedriver无法正确到达有关。

1. 请确保您的chromedriver和Google chrome浏览器是同一版本。例如，如果您的浏览器版本为81.xxxx，请确保您的chromedriver版本也为81.xxx

2. 将您的chromedriver放在与main.py所在的目录相同的目录中

3. 将self.b = Browser('chrome', **executable_path)行更改为self.b = Browser('chrome', **executable_path, headless=False)
