【问题描述】：
我正在尝试使用在 repo 中找到的一些代码
https://github.com/AlbanyCompSci/aeries-api
基本上是为了帮助我登录这个名为 aeries 的年级门户网站并为我的孩子提供高中成绩。但我不断收到与“phantomjs”相关的错误。同样在它引发关于 chrome 需要无头的错误之前。
下面有一些示例，我从本地目录加载模块，并添加了一些代码来尝试解决错误。我在带有 python 3.6 的 jupyter notebook 中的 mac 上运行它。非常感谢任何提示。
代码：
import pandas as pd
import numpy as np
import Main as m
import Gradebooks as Gb
import GradebookDetails as GD
import Assignments as Ag
import AeriesSession as Ar
# below added to try to resolve phantomjs errors
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = Options()
options.add_argument('headless')
driver = webdriver.PhantomJS(executable_path='/Users/username/Desktop/Stuff/Aeries/api_version/phantomjs-2.1.1-macosx/bin/phantomjs.exe')
警告：
/Users/username/anaconda/envs/py36/lib/python3.6/site-packages/selenium/webdriver/phantomjs/webdriver.py:49: UserWarning: Selenium support for PhantomJS has been deprecated, please use headless versions of Chrome or Firefox instead

【问题讨论】：
-
Phantomjs 现在已被弃用。您可以使用 Chrome 无头
-
@AnkurSingh 感谢您这么快回复我。我对此很陌生。我正在运行在 chrome 上的 jupyter 笔记本的单元格中运行它。我添加了所有试图解决问题的“webdriver”内容。但在我启动 chrome 之前，我需要从终端做些什么吗？能否请您概括地告诉我 phantomjs 和 chrome headless 正在做什么？
-
什么都不需要做 ..from selenium import webdriver from selenium.webdriver.chrome.options import Options options = Options() options.add_argument('headless') #downlod Chrome driver.exe driver = webdriver.Chrome(executable_path=os.path.abspath(“chromedriver”), chrome_options=chrome_options) driver.set_window_size(1120, 550) driver.get("duckduckgo.com/") driver.find_element_by_id('search_form_input_homepage').send_keys(" realpython") driver.find_element_by_id("search_button_homepage").click() print driver.current_url driver.quit()
-
试试上面的代码。
-
@AnkurSingh 再次感谢您的帮助。我添加了对原始帖子的更新。我下载了 chromedriver.exe 并尝试运行您建议的代码。现在我收到 chrome_options 的名称错误。我的代码有错误吗？
