Selenium WebDriverException 'chromedriver.exe‘需要在路径中

Question

我试图在python 刮刀器中使用selenium，但是当我试图运行该程序时，会出现以下错误：

/usr/local/bin/python3 /Users/xxx/Documents/Python/hello.py                                     
Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/selenium/webdriver/common/service.py", line 72, in start
    self.process = subprocess.Popen(cmd, env=self.env,
  File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/subprocess.py", line 854, in __init__
    self._execute_child(args, executable, preexec_fn, close_fds,
  File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/subprocess.py", line 1702, in _execute_child
    raise child_exception_type(errno_num, err_msg, err_filename)
FileNotFoundError: [Errno 2] No such file or directory: '/Users/xxx/Documents/Python/chromedriver.exe'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/Users/xxx/Documents/Python/hello.py", line 9, in <module>
    wd = webdriver.Chrome(executable_path=DRIVER_PATH)
  File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/selenium/webdriver/chrome/webdriver.py", line 73, in __init__
    self.service.start()
  File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/selenium/webdriver/common/service.py", line 81, in start
    raise WebDriverException(
selenium.common.exceptions.WebDriverException: Message: 'chromedriver.exe' executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home

下面是python代码：

from urllib.request import urlopen
from bs4 import BeautifulSoup
import re
from selenium import webdriver


DRIVER_PATH = '/Users/xxx/Documents/Python/chromedriver.exe'

wd = webdriver.Chrome(executable_path=DRIVER_PATH)

我认为问题在于我没有正确地在变量DRIVER_PATH中指定文件路径，但我不确定

我正在使用Mac

Answer 1

您需要更新DRIVER_PATH以包括根目录(通常为C:\ )。

DRIVER_PATH = 'C:/Users/xxx/Documents/Python/chromedriver.exe'

或者，您可以按照本教程将包含chromedriver.exe文件夹(通常是chromedriver_win32文件夹)的路径添加到Path环境变量中：

Answer 2

我会尝试这个(只是添加'r')：

wd = webdriver.Chrome(executable_path=r'/Users/xxx/Documents/Python/chromedriver.exe')

如果你认为是文件，那就去检查一下：

import os.path
os.path.exists(DRIVER_PATH)

此外，美汤是使用威尔与urllib2 https://www.pythonforbeginners.com/beautifulsoup/beautifulsoup-4-python

import urllib2
url = "https://www.URL.com"
content = urllib2.urlopen(url).read()
soup = BeautifulSoup(content)

Answer 3

你在文件的名字上弄错了。

"chomedriver.exe“是用于windows的。

如果对Mac使用macOS和chromedriver，那么文件名应该是"chomedriver“，而不是".exe”。

我也有同样的问题，但这解决了它。
