Using Silenium with webdriver for Chrome and getting "Permission denied" or "No such file or directory" (Mac)

I'm trying to use Python with selenium to automate downloading files from a website, but when I try to call chromeDriver I get an error. I've tried two different ways but without success. Any ideas on how I can fix one way or the other to work?

Way 1:

from selenium import webdriver
driver = webdriver.Chrome(executable_path=r'/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages')

This produces the error:

Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/selenium/webdriver/common/service.py", line 72, in start
    self.process = subprocess.Popen(cmd, env=self.env,
  File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/subprocess.py", line 854, in __init__
    self._execute_child(args, executable, preexec_fn, close_fds,
  File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/subprocess.py", line 1702, in _execute_child
    raise child_exception_type(errno_num, err_msg, err_filename)
PermissionError: [Errno 13] Permission denied: '/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages'

During handling of the above exception, another exception occurred:

  File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/selenium/webdriver/chrome/webdriver.py", line 73, in __init__
    self.service.start()

    raise WebDriverException(

Way 2

from selenium import webdriver
driver = webdriver.Chrome(executable_path=r'/Chrome/chromedriver.exe')

This produces the error:

Traceback (most recent call last):
