python - 未找到 Chromedriver 路径？ - Selenium - MacOS

Question

我已经在 MacOS 上下载了 Selenium 和 Chromedriver，但似乎无法在 IDLE Python Shell 上执行:

driver = webdriver.Chrome()

错误信息返回:

Traceback (most recent call last):
 File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/selenium/webdriver/common/service.py", line 76, in start
stdin=PIPE)
 File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/subprocess.py", line 756, in __init__

 raise child_exception_type(errno_num, err_msg, err_filename)
 FileNotFoundError: [Errno 2] No such file or directory: 'chromedriver': 'chromedriver'

  During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<pyshell#6>", line 1, in <module>
  driver = webdriver.Chrome()
 File 
"/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-

selenium.common.exceptions.WebDriverException: Message: 'chromedriver' 
 executable needs to be in PATH. Please see

我尝试将 Chromedriver 设置在正确的路径中，方法是将其放置在 usr/local/bin 中并将其放置在所附图像中的 selenium 文件夹中。但是，我不确定它是否在正确的位置，因为仍然出现相同的错误。

我该如何解决这个问题？

非常感谢!

如您所知，主要错误是您的 chromedriver 可执行文件不在 PATH 中。在 Python 脚本中执行以下操作来指定 PATH:

import sys
path = '/path/to/your/chromedriver/executable'
sys.path.append(path)

# then continue your script

据我所知，chromedriver 可执行文件不需要位于 bin 目录中即可正常工作；你可以把它放在任何地方，只要你使用上面的代码指定你的程序在哪里可以找到它。
