Selenium WebDriverException: chrome недоступно

0 голосов
/ 26 апреля 2020

Я пытаюсь очистить страницу Javascript с помощью Python. Видя, что Phantom JS уже устарел, я пытаюсь использовать безголовый Chrome веб-драйвер для загрузки страницы безрезультатно.

Драйвер загружен, но код в большинстве случаев дает сбой либо во время ожидания, либо при получении источника страницы.

Код: 

from selenium import webdriver
from selenium.common.exceptions import TimeoutException
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.ui import WebDriverWait

from webdriver_manager.chrome import ChromeDriverManager

def fetch(search):
    BASE_URL = 'https://ko.dict.naver.com/#/search?query='
    DELAY = 10
    html = None

    options = webdriver.ChromeOptions()
    options.add_argument('--headless')
    options.add_argument('--no-sandbox')
    driver = webdriver.Chrome(ChromeDriverManager().install(), chrome_options=options)

    search_url = BASE_URL + search
    driver.get(search_url)

    try:
        WebDriverWait(driver, DELAY).until(EC.presence_of_element_located((By.ID, 'content')))
    except TimeoutException:
        print('Took too long to load.')
    else:
        html = driver.page_source
    finally:
        driver.quit()

    return html

Stacktrace:
