title: No module named "urllib3" Selenium Python
body: <p>I have worked with Selenium before and everything was fine but suddenly it stopped working. I have tried to reinstall Python, Selenium and updated pip. When I run this simple Python Selenium script :</p>
  
  <pre><code>from selenium import webdriver
  from time import sleep
  driver = webdriver.Chrome('drivers/chromedriver.exe')
  driver.get("http://www.python.org")
  sleep(5)
  </code></pre>
  
  <p>It returns the following error message:</p>
  
  <pre><code>Traceback (most recent call last):
    File "C:\Users\Jan\Desktop\Python\Selenium\test.py", line 1, in &lt;module&gt;
      from selenium import webdriver
    File "C:\Users\Jan\Desktop\Python\Selenium\selenium\webdriver\__init__.py", line 18, in &lt;module&gt;
      from .firefox.webdriver import WebDriver as Firefox  # noqa
    File "C:\Users\Jan\Desktop\Python\Selenium\selenium\webdriver\firefox\webdriver.py", line 29, in &lt;module&gt;
      from selenium.webdriver.remote.webdriver import WebDriver as RemoteWebDriver

      from .remote_connection import RemoteConnection
    File "C:\Users\Jan\Desktop\Python\Selenium\selenium\webdriver\remote\remote_connection.py", line 24, in &lt;module&gt;
      import urllib3
  ModuleNotFoundError: No module named 'urllib3'
  </code></pre>
  
  <p>Is there something I am missing?
  Thanks for your help.</p>
