chromedriver 可执行文件需要位于 PATH 中

Question

我知道这个问题已经被问过很多次了，我也尝试了所有的答案，但它对我不起作用。我已经在一个简单的脚本上尝试了选项和 PATH 方法来提取网页的标题，并且它有效。但对于所有这些代码，它给了我上述错误

import requests
import pandas as pd
from bs4 import BeautifulSoup
from selenium import webdriver
import time
from selenium.webdriver.common.keys import Keys

HEADERS = {'User-Agent' : 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/105.0.0.0 Safari/537.36'}
options = webdriver.ChromeOptions() 
options.add_experimental_option("excludeSwitches", ["enable-logging"])
PATH = r"C:\Users\hp\Downloads\chromedriver\chromedriver.exe"
driver = webdriver.Chrome(options=options , executable_path=PATH)

def get_current_url(url, jobTitle, location):
    driver = webdriver.Chrome()
    driver.get(url)
    time.sleep(3)
    driver.find_element_by_xpath('//*[@Id="text-input-what"]').send_keys(jobTitle)
    time.sleep(3)
    driver.find_element_by_xpath('//*[@Id="text-input-where"]').send_keys(location)
    time.sleep(3)
    driver.find_element_by_xpath('/html/body/div').click()
    time.sleep(3)
    try:
        driver.find_element_by_xpath('//*[@id="jobsearch"]/button').click()
    except:
        driver.find_element_by_xpath('//*[@id="whatWhereFormId"]/div[3]/button').click()
        current_url = driver.current_url
    return current_url

current_url = get_current_url('https://pk.indeed.com/', 'Python Developer', 'Karachi')
print(current_url)

Answer 1

解决方案

您可以使用

ChromeDriverManager

摆脱所有驱动程序、版本问题

• 如果您正在使用 ChromeDriverManager - Webdriver Manager Python 你不必显式下载

  ChromeDriver

  因为它 自动下载。

• 如果您想使用下载的

  ChromeDriver

  ，您可以避免使用

  ChromeDriverManager - Webdriver Manager

使用

ChromeDriverManager

，您可以使用以下代码块：

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from webdriver_manager.chrome import ChromeDriverManager

driver = webdriver.Chrome(service=Service(ChromeDriverManager().install()))
driver.maximize_window()
driver.get("https://www.google.com")

下载特定版本的 ChromeDriver 您可以使用以下代码块：

from selenium import webdriver
from selenium.webdriver.chrome.service import Service

s = Service('C:/Users/hp/Downloads/chromedriver/chromedriver.exe')
driver = webdriver.Chrome(service=s)

注意：如果您使用的是

Linux / MAC O SX

系统，您需要剥离扩展部分，即

.exe

，因为它仅适用于

windows

平台。

Answer 2

而不是

PATH = r"C:\Users\hp\Downloads\chromedriver\chromedriver.exe"
driver = webdriver.Chrome(options=options , executable_path=PATH)

尝试

from selenium.webdriver.chrome.service import Service

webdriver_service = Service(r'C:\Users\hp\Downloads\chromedriver\chromedriver.exe')
driver = webdriver.Chrome(service=webdriver_service)

Answer 3

您有 2 个选择。

首先，您可以将

C:\Users\hp\Downloads\chromedriver\chromedriver.exe

添加到系统路径。请按照以下指南操作。

或者第二，当你使用r字符串时，你需要像这样改变斜杠。如果你翻转它应该会起作用。

PATH = r"C:/Users/hp/Downloads/chromedriver/chromedriver.exe"
