Python Selenium Traceback（最近一次调用）：

Question

我正在尝试将硒用于python web scraper，但是当我尝试运行该程序时，出现以下错误：

"/Applications/Python 3.8/IDLE.app/Contents/MacOS/Python" "/Applications/PyCharm CE.app/Contents/helpers/pydev/pydevd.py" --multiproc --qt-support=auto --client 127.0.0.1 --port 52548 --file /Users/xxxx/git/python/python_crawler_example_01/naver_crawling.py
pydev debugger: process 3004 is connecting

Connected to pydev debugger (build 192.7142.56)

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

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  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' executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home


Process finished with exit code 1

这是我的错误代码：

from selenium import webdriver
from bs4 import BeautifulSoup as bs

import time
import os, sys

driver = webdriver.Chrome()

time.sleep(2)

driver.close()

我正在使用macos和pycharm

Answer 1

driver = webdriver.Chrome(executable_path = "/chromedriver.exe")
