Question

我决定从 rickroll 程序开始，只是为了好玩和学习基础知识。我从这里学到：https://towardsdatascience.com/controlling-the-web-with-python-6fceb22c5f08 和这里：https://sites.google.com/a/chromium.org/chromedriver/getting-started 我以前用过 python，但几年没用了，我的代码在这里不起作用：

import os
import selenium
import time
from selenium import webdriver

driver = webdriver.Chrome('/path/to/chromedriver')  # Optional argument, if not specified will search path.
driver.get('http://www.google.com/');
time.sleep(5) # Let the user actually see something!
search_box = driver.find_element_by_name('q')
search_box.send_keys('ChromeDriver')
search_box.submit()
time.sleep(5) # Let the user actually see something!

webdriver.Chrome()
driver.get('https://www.youtube.com/')
time.sleep(5)
id_box = driver.find_element_by_id('search')
id_box.send_keys('Never gonna give you up')
time.sleep(5)
rickroll = driver.find_element_by_id('Rick Astley - Never Gonna Give You Up (Video)')
rickroll.click()
time.sleep(180)
driver.quit

我收到了这个错误信息：

During handling of the above exception, another exception occurred:

selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home

我将 chromedriver 添加到 PATH 但它仍然出现此错误

Answer 1

如果您在 PATH 中有驱动程序的路径，为什么要将其作为参数提供？也许使用 sys.environ['ENV_VARIABLE_NAME'] 作为参数 executable_path。
