在Mac上使用Jupyter Notebook的phantomjs问题

标签: python-3.x selenium selenium-webdriver webdriver phantomjs

我正在尝试使用在存储库中找到的一些代码

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,并提高我的孩子的高中成绩。但是我不断收到与“ phantomjs”有关的错误。同样,在抛出关于chrome的错误之前,它必须是无头的。

下面有一些示例,这些示例是从本地目录加载模块的,并添加了一些代码来尝试解决错误。我正在使用python 3.6在jupyter笔记本中的Mac上运行它。任何提示都非常感谢。

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

答案 0 :(得分:0)

此错误消息...

WebDriverException: Message: 'phantomjs.exe' executable needs to be in PATH.

...表示在指定位置找不到 phantomjs.exe

似乎有些混乱,如下所示:

  • PhantomJS浏览器 本身是一款无头网页浏览器,可使用JavaScript编写脚本,该脚本可在 Windows macOS Linux FreeBSD 。因此,您无需显式传递参数 headles 即可删除它。
  • 您没有提到底层的操作系统
    • 如果您使用的是 Linux 64位操作系统,则需要从Download PhantomJS下载phantomjs-2.1.1-linux-x86_64.tar.bz2,提取二进制文件,同时提及 phantomjs的绝对路径二进制文件,您需要去除扩展部分(即.exe
    • 如果您使用的是 Linux 32位操作系统,则需要从Download PhantomJS下载phantomjs-2.1.1-linux-i686.tar.bz2,提取二进制文件,同时提及 phantomjs的绝对路径二进制文件,您需要去除扩展部分(即.exe
    • 如果您使用的是 Mac OS X ,则需要从Download PhantomJS下载phantomjs-2.1.1-macosx.zip,提取二进制文件,同时提及 phantomjs的绝对路径< / strong>二进制文件,您需要去除扩展部分(即.exe
    • 如果您使用的是 Windows操作系统,则需要从Download PhantomJS下载phantomjs-2.1.1-linux-x86_64.tar.bz2,提取二进制文件,并提及 phantomjs 的路径>二进制文件,您需要提供包括扩展名(即phantomjs.exe)的绝对路径
  • 尽管您看到了弃用通知,但支持仍然存在。因此暂时您可以忽略该错误:

    C:\Python\lib\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
      warnings.warn('Selenium support for PhantomJS has been deprecated, please use headless '
    
  • Windows8 系统上,这是工作代码:

    from selenium import webdriver
    
    driver = webdriver.PhantomJS(executable_path=r'C:\\Utility\\phantomjs-2.1.1-windows\\bin\\phantomjs.exe')
    driver.get('https://www.google.com/')
    print(driver.title)
    driver.quit()
    
  • 控制台输出:

    C:\Python\lib\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
      warnings.warn('Selenium support for PhantomJS has been deprecated, please use headless '
