phantomjs issue on mac with jupyter notebook

问题

I’m trying to experiment with some code I found at the repo

https://github.com/AlbanyCompSci/aeries-api

basically to help me login in to this grade portal called aeries and pull my kids high school grades. But I keep getting errors related to “phantomjs”. Also before it was throwing an error about chrome needing to be headless.

I’ve got some examples below where I’m loading the module from a local directory and I’ve added the some code to try to resolve the errors. I’m running it on a mac in a jupyter notebook with python 3.6. Any tips greatly appreciated.

Code:

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')

Warning:

This error message...

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

...implies that the phantomjs.exe was not found in the specified location.

There seems to be a bit of messup as follows:

PhantomJS Browser itself is a headless web browser scriptable with JavaScript which can run on Windows, macOS, Linux, and FreeBSD. So you don't need to explicitly pass the argument headles and you can remove it.
You havn't mentioned about the underlying Operating System.
- If you are on Linux 64 bit OS you need to download the phantomjs-2.1.1-linux-x86_64.tar.bz2 from Download PhantomJS, extract the binary and while mentioning the absolute path of the phantomjs binary you need to strip off the extension part (i.e. .exe)
- If you are on Linux 32 bit OS you need to download the phantomjs-2.1.1-linux-i686.tar.bz2 from Download PhantomJS , extract the binary and while mentioning the absolute path of the phantomjs binary you need to strip off the extension part (i.e. .exe)
- If you are on Mac OS X you need to download the phantomjs-2.1.1-macosx.zip from Download PhantomJS , extract the binary and while mentioning the absolute path of the phantomjs binary you need to strip off the extension part (i.e. .exe)
- If you are on Windows OS you need to download the phantomjs-2.1.1-linux-x86_64.tar.bz2 from Download PhantomJS , extract the binary and while mentioning the path of the phantomjs binary you need to provide the absolute path including the extension (i.e. phantomjs.exe)

Though you observe the deprecation notice but the support is still there. So for the time being you can ignore the error:

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 '

On Windows8 system here is the working code:

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()

Console Output:

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 '
