Selenium＆WebDriver for Chrome无法在JupyterLabMac上运行

问题描述

背景：
我正在尝试在Mac上使用Selenium来刮取食谱网站，但是在使用Selenium初始化Chrome WebDriver时遇到问题。我下载了chromedriver（Windows和Mac版本），并且与JupyterNotebook文件位于同一目录中：

代码：

from bs4 import BeautifulSoup
import requests
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import selenium
import time
import csv
import os
import sys

driver=webdriver.Chrome('chromedriver')
url = "https://www.simplyrecipes.com/index/"
driver.get(url) 
response=requests.get(url)
soup=BeautifulSoup(response.text,'html.parser')

错误：

FileNotFoundError                         Traceback (most recent call last)

   1552                 raise child_exception_type(err_msg)

FileNotFoundError: [Errno 2] No such file or directory: 'chromedriver': 'chromedriver'

During handling of the above exception,another exception occurred:

     85             elif err.errno == errno.EACCES:

帮助：
我已经阅读了documentation，并且很确定我已经设置了所有内容，所以我根本无法理解我要去哪里。

任何建议将不胜感激

解决方法

即使Juypternote与chrome驱动程序位于同一路径，您仍然必须指定路径-

from bs4 import BeautifulSoup
import requests
from splinter import Browser
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import selenium
import time
import csv
driver=webdriver.Chrome("/Users/williamforsyth/Documents/homeworks/Homework_Repos/group-project-2/Kathryn/chromedriver")
url = "https://www.simplyrecipes.com/index/"
driver.get(url) 
response=requests.get(url)
soup=BeautifulSoup(response.text,'html.parser')
