Kann nicht mit Selen beginnen mit Python

Question

Ich habe gerade mit der Arbeit an Selen begonnen. Aber ich habe dieses Problem

Traceback (most recent call last): 
    File "<stdin>", line 1, in <module> 
    File "/usr/local/lib/python3.5/dist-packages/selenium/webdriver/remote/webdriver.py", line 248, in get 
    self.execute(Command.GET, {'url': url}) 
    File "/usr/local/lib/python3.5/dist-packages/selenium/webdriver/remote/webdriver.py", line 234, in execute 
    response = self.command_executor.execute(driver_command, params) 
    File "/usr/local/lib/python3.5/dist-packages/selenium/webdriver/remote/remote_connection.py", line 401, in execute 
    return self._request(command_info[0], url, body=data) 
    File "/usr/local/lib/python3.5/dist-packages/selenium/webdriver/remote/remote_connection.py", line 431, in _request 
    self._conn.request(method, parsed_url.path, body, headers) 
    File "/usr/lib/python3.5/http/client.py", line 1106, in request 
    self._send_request(method, url, body, headers)

    self.endheaders(body) 
    File "/usr/lib/python3.5/http/client.py", line 1102, in endheaders 
    self._send_output(message_body) 
    File "/usr/lib/python3.5/http/client.py", line 934, in _send_output 
    self.send(msg) 
    File "/usr/lib/python3.5/http/client.py", line 877, in send 
    self.connect() 
    File "/usr/lib/python3.5/http/client.py", line 849, in connect 
    (self.host,self.port), self.timeout, self.source_address) 
    File "/usr/lib/python3.5/socket.py", line 711, in create_connection 
    raise err 
    File "/usr/lib/python3.5/socket.py", line 702, in create_connection 
    sock.connect(sa) 
ConnectionRefusedError: [Errno 111] Connection refused 

Ich habe versucht, im Internet suchen. Meine Versionen von Selen und Firefox sind aktuell. Da es nur der Anfang war, hatte ich drei einfache Zeilen aus dem Internet und versuchte das zu tun.

>>> from selenium import webdriver 
>>> br = webdriver.Firefox() 
>>> br.implicitly_wait(15) 
>>> br.get('http://youtube.com')

Stellen Sie sicher, neueste Version von Firefox-Browser & geckodriver haben.

1. Hier finden Sie die neueste Version des Treibers:

   Um aktuelle Gecko folgt vor, zu installieren wget https://github.com/mozilla/geckodriver/releases/download/v0.18.0/geckodriver-v0.18.0-arm7hf.tar.gz

2. Entpacken Sie die Datei mit tar -xvzf geckodriver*

3. ausführbar machen: chmod +x geckodriver

4. Fügen Sie den Treiber auf Ihrem PATH, so dass andere Werkzeuge können sie finden: export PATH=$PATH:/path-to-extracted-file/geckodriver
