Невозможно запустить Selenium на Ubuntu с Python

0 голосов
/ 18 июня 2020

Я не могу запустить или установить селен в Ubuntu 18.04.3 ... Я следил за этим руководством: https://medium.com/@hoppy / how-to-test-or-scrape- javascript -rendered-sites-with- python -selenium-a-beginner-step-by-c137892216aa также с настройкой digitalocean.

Я пробовал разные вещи ... Я установил geckodriver в / var / bin в / var / local / bin добавлено как в PATH, попытка с путем в коде, так и без попытки с помощью firefox (предпочтительно) ... ничего не помогает

Этот код: 

import time
from selenium import webdriver


driver = webdriver.Chrome('/usr/bin/chromedriver') # Optional argument, if not specified will search path.
driver.get('http://www.google.com/');
time.sleep(5) # Let the user actually see something!
search_box = driver.find_element_by_name('q')
search_box.send_keys('ChromeDriver')
search_box.submit()
time.sleep(5) # Let the user actually see something!
driver.quit()

Завершается: 

selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to start: exited abnormally.
selenium.common.exceptions.WebDriverException:: command not found

Этот код: 

from selenium import webdriver
from selenium.webdriver.firefox.options import Options

options = Options()
options.headless = True
driver = webdriver.Firefox(firefox_options=options)

С этой ошибкой:

During handling of the above exception, another exception occurred:

Пожалуйста, помогите. Пробовал много решений, но ни у кого не получилось ...

options.addArguments("--disable-dev-shm-usage"); // overcome limited resource problems
options.addArguments("--no-sandbox"); // Bypass OS security model

У меня работает на драйвере chrome.
