Я запускаю скрипт на AWS (Ubunut) экземпляре EC2. Это веб-скребок, который использует селен / хромедрайвер и безголовый chrome для очистки некоторых веб-страниц. Раньше у меня был этот скрипт без проблем, но сегодня я получаю сообщение об ошибке. Вот скрипт:
options = Options()
options.add_argument('--no-sandbox')
options.add_argument('--window-size=1420,1080')
options.add_argument('--headless')
options.add_argument('--disable-dev-shm-usage')
options.add_argument('--disable-gpu')
options.add_argument("--disable-notifications")
options.binary_location='/usr/bin/chromium-browser'
driver = webdriver.Chrome(chrome_options=options)
#Set base url (SAN FRANCISCO)
base_url = 'https://www.bandsintown.com/en/c/san-francisco-ca?page='
events = []
for i in range(1,90):
#cycle through pages in range
driver.get(base_url + str(i))
pageURL = base_url + str(i)
print(pageURL)
Когда я запускаю этот скрипт из ubuntu, я получаю эту ошибку:
Traceback (most recent call last):
File "BandsInTown_Scraper_SF.py", line 91, in <module>

Я подтвердил, что я использую ту же версию браузера Chromedriver / Chromium :
ChromeDriver 79.0.3945.130 (e22de67c28798d98833a7137c0e22876237fc40a-refs/branch-heads/3945@{#1047})
Chromium 79.0.3945.130 Built on Ubuntu , running on Ubuntu 18.04
Любая помощь приветствуется, потому что я в тупике. Что бы это ни стоило, у меня это работает на компьютере ma c, и у меня есть несколько скриптов веб-скрепинга, подобных этому, выполняющихся на одном и том же экземпляре EC2 (пока только 2 скрипта, так что не так много). Спасибо.
ОБНОВЛЕНИЕ: теперь я также получаю следующие ошибки при попытке запустить этот скрипт в Ubuntu:

Наконец, вот мое ежемесячное использование AWS в месяц, которое не не показывать превышение квоты памяти.
