Question

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

driver = webdriver.Chrome()

错误消息返回：

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

selenium.common.exceptions.WebDriverException: Message: 'chromedriver' 
 executable needs to be in PATH. Please see 
https://sites.google.com/a/chromium.org/chromedriver/home

我试图将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，因为仍然会出现相同的错误。

我该如何解决？

非常感谢您！

您知道，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以指定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目录中才能正常工作；您可以将其放置在任何地方，只要使用上面的代码指定程序可以在哪里找到它即可。
