关于selenium

蛊惑的心

今天刚刚装selenium，看网上的教程运行了一段代码

from selenium import webdriver
browser = webdriver.Chrome()
browser.get('http://www.baidu.com/')

然后chrome打开了，但是百度网页却没有打开，而且一段时间后自动退出chrome且报错
报错如下：
Traceback (most recent call last):
  File "C:/Users/头条杀机/AppData/Local/Programs/Python/Python37/aa.py", line 3, in <module>
    browser = webdriver.Chrome()

我的chrome版本是68.0.3440.84
chrome驱动版本是2.4（它写着支持67-69），环境变量我设置在另一个盘符下了，和chrome.exe不在一个文件夹（不知道是否有影响）
所以为什么会出现这样的错误呢，为什么和教程结果不一样呢。。

蛊惑的心

我将chrome驱动和chrome.exe放在一个文件夹下了，而且改了环境变量，这一次直接报错，打都打不开，之所以换是因为我觉得之前打开的是cent的chrome.exe
报错如下：

During handling of the above exception, another exception occurred:

试试将chromedriver放在python目录里（与python.exe文件同一目录）
