import error: cannot import name 'HTTPError' from urllib3.exceptions

Question

I had a .py file that used to work for web scraping gas prices from gasbuddy using selenium and phantomjs. It used to work, but it stopped all of a sudden. So I uninstalled and reinstalled selenium and phantomJS. I uninstalled and reinstalled Python 3 using homebrew. I even erased my MacBook and reinstalled Sierra on it, and reinstalled everything else What doesn't make sense to me is that I'm getting importing errors for modules I'm not even importing.

import os
from selenium import webdriver
import warnings

warnings.filterwarnings("ignore")
driver = webdriver.PhantomJS(service_log_path=os.path.devnull)

driver.get('https://www.gasbuddy.com/station/155967')
price = driver.find_element_by_xpath('//*[@id="container"]/div/div[3]/div/div/div/div[1]/div[2]/div[1]/div/div/div/div/h1')
print(price.text)

and the errors that I get are:

I even updated everything. Installing and reinstalling urllib didn't make a difference. I've also tried using other webscraping methods (lxml, etc.) but to no avail. Any answers?

tl;dr
You have a circular import of urllib3.exceptions. /Users/igisan/Desktop/scripts/calendar.py shadows the calendar module of the Python standard lib. Rename that module.

Your Python env appears to be quite a bit messy. Importing webdriver looks normal up to the point where the underlying import of urllib3.exceptions resolves http.client not to the site-packages of that local Python 3.7 interpreter but to that of what appears to be a homebrew installation of Python 3.7.2 under /usr/local/Cellar.

  File "/usr/local/lib/python3.7/site-packages/urllib3/packages/six.py", line 82, in _import_module
    __import__(name)
  File "/usr/local/Cellar/python/3.7.2_2/Frameworks/Python.framework/Versions/3.7/lib/python3.7/http/client.py", line 71, in <module>
    import email.parser

From there you have a normal chain of imports within that homebrew module until email._parseaddr tries to import calendar.
This import should go to the calendar.py module in the Python standard lib, but since you have a calendar.py in your /Users/igisan/Desktop/scripts folder, which apparently is added to sys.path (presumably through PYTHONPATH) the interpreter resolves to your calendar.py.

  File "/usr/local/Cellar/python/3.7.2_2/Frameworks/Python.framework/Versions/3.7/lib/python3.7/email/_parseaddr.py", line 16, in <module>
    import time, calendar
  File "/Users/igisan/Desktop/scripts/calendar.py", line 2, in <module>
    from pyicloud import PyiCloudService

Your calendar.py imports some class from the pyicloud package, which results in an attempt to import requests, which results in an attempt to import urllib3.exceptions.
This becomes a circular import at that point. Importing urllib3.exceptions leads to the import of a module that tries to import urllib3.exceptions.
This issue should be resolved by renaming /Users/igisan/Desktop/scripts/calendar.py to something that does not shadow the module calendar from the standard lib.
