How to fix py3 error?

Question

linux

there is a program, I immediately say I copy-pasted it, for the purpose of familiarization, here it is:

from vk_api.longpoll import VkLongPoll, VkEventType
import vk_api
from datetime import datetime

login, password = "мой логин", "пароль"
vk_session = vk_api.VkApi(login=login, password=password, app_id=2685278)
vk_session.auth(token_only=True)

token = "токен"
vk_session = vk_api.VkApi(token=token)

session_api = vk_session.get_api()
longpoll = VkLongPoll(vk_session)
#While True здесь оказался не нужен. Его функцию выполняет for event in longpoll.listen(): Спасибо подписчику за это уточнение.

for event in longpoll.listen():
    if event.type == VkEventType.MESSAGE_NEW:
        print('Сообщение пришло в: ' + str(datetime.strftime(datetime.now(), "%H:%M:%S")))
        print('Текст сообщения: ' + str(event.text))

when I run it from the console, I get this:

from: can't read /var/mail/vk_api.longpoll
import-im6.q16: not authorized `vk_api' @ error/constitute.c/WriteImage/1037.
from: can't read /var/mail/datetime
./vkBot.py: 5: ./vkBot.py: login,: not found
./vkBot.py: 6: ./vkBot.py: Syntax error: "(" unexpected

changed:
I realized that I do not have this lib installed and I need to install it, but when installing pip, it gives errors
if I run it without root

Collecting vk_api

Answer 1

Syntax error: "(" unexpected - check this place, apparently there is no parenthesis.
