Selenium错误:“chromedriver”可执行文件需要位于路径[duplicate]中

我的电脑上有运行Debian9的Chromium scraper.py

from selenium import webdriver
import time

options = webdriver.ChromeOptions()
options.add_argument("--ignore-certificate-errors")
options.add_argument("--test-type")
options.binary_location = "/usr/bin/chromium"

driver = webdriver.Chrome(chrome_options=options)
driver.get("https://python.org")

铬二元在指定位置。当我运行python时 刮刀.py ,我得到这个错误。

Traceback (most recent call last):
