Well - i am trying to figure out the simplest approach to gather data from clutch.io
- i have tried various approaches to gather data from a website (clutch.io ) but all seems to fail:
see here
from bs4 import BeautifulSoup
from selenium import webdriver
driver = webdriver.Chrome()
url = 'https://clutch.co/it-services/msp'
driver.get(url=url)
soup = BeautifulSoup(driver.page_source,"lxml")
links = []
for l in soup.find_all('li',class_='website-link website-link-a'):
results = (l.a.get('href'))
links.append(results)
print(links, "\n", "Count links - ", len(links))
throws back this error:

This error message...
WebDriverException: Message: 未知错误: 无法找到 Chrome 二进制文件
...意味着ChromeDriver无法在系统的默认位置找到[tag:google-chrome]二进制文件，或者根本没有安装它。
在非标准位置使用 Chrome 可执行文件
您需要使用以下方式覆盖默认的_Chrome 二进制文件位置_，使用 自定义位置：
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = Options()
options.binary_location = "C:\\Program Files\\Google\\Chrome\\Application\\chrome.exe" # 根据我的 Win10 操作系统
s = Service('C:\\BrowserDrivers\\chromedriver.exe')
driver = webdriver.Chrome(service=s, options=options)
driver.get('http://google.com/')
print("Chrome 浏览器已启动")

- WebDriverException: 未知错误: 无法找到 Chrome 二进制文件错误与 Python 中的 Selenium 以及旧版本 Google Chrome
- 使用 Selenium 时是否需要安装 Chrome，还是只需 chromedriver？
英文:
This error message...
WebDriverException: Message: unknown error: cannot find Chrome binary
...implies that the ChromeDriver was unable to find the [tag:google-chrome] binary in the default location of your system or it wasn't installed at all.
Using a Chrome executable in a non-standard location
You need to override the default Chrome binary location with the custom location as follows:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = Options()
options.binary_location = "C:\\Program Files\\Google\\Chrome\\Application\\chrome.exe" # as per my Win10 OS box
s = Service('C:\\BrowserDrivers\\chromedriver.exe')
driver = webdriver.Chrome(service=s, options=options)
driver.get('http://google.com/')
print("Chrome Browser Invoked")
