python - 由于OSError无法运行python beautifulsoup Web抓取程序

Question

我正在尝试通过网络抓取Instagram帐户，但出现错误:

Traceback (most recent call last):
  File "C:/Users/User/Desktop/python/webscraper.py", line 11, in <module>
    browser = webdriver.Chrome(r"C:\Users\User\Downloads\chromedriver_win32.zip")
  File "C:\Users\User\AppData\Local\Programs\Python\Python38-32\lib\site-packages\selenium\webdriver\chrome\webdriver.py", line 73, in __init__
    self.service.start()
  File "C:\Users\User\AppData\Local\Programs\Python\Python38-32\lib\site-packages\selenium\webdriver\common\service.py", line 72, in start
    self.process = subprocess.Popen(cmd, env=self.env,

    hp, ht, pid, tid = _winapi.CreateProcess(executable, args,
OSError: [WinError 193] %1 is not a valid Win32 application

我正在尝试运行以下代码:

from selenium import webdriver
from bs4 import BeautifulSoup as bs
import time
import re
from urllib.request import urlopen
import json
from pandas.io.json import json_normalize
import pandas as pd, numpy as np

username='dailydogsnapz'
browser = webdriver.Chrome(r"C:\Users\User\Downloads\chromedriver_win32.zip")
browser.get('https://www.instagram.com/'+username+'/?hl=en')
Pagelength = browser.execute_script("window.scrollTo(0, document.body.scrollHeight);")

我不明白我在做什么错。我尝试查找此错误，但是GitHub上的解决方案或其他堆栈溢出问题都无法解决该问题。

Answer 1

问题:

browser = webdriver.Chrome(r"C:\Users\User\Downloads\chromedriver_win32.zip")

您指向的是.zip文件，而不是chrome驱动程序的可执行文件。您需要解压缩该文件，然后指向该可执行文件。
解:
将文件解压缩到同一位置后，您可以执行以下操作:

browser = webdriver.Chrome(r"C:\Users\User\Downloads\chromedriver_win32.exe")

请注意，从.zip更改为.exe意味着可执行文件。
