Selenium получил ошибку BadStatusLine при производстве. Идя хорошо акушера отладки

Question

Существует скрипт для очистки комментариев от Instagram по ключевым словам:

# coding: utf-8 
from selenium import webdriver 
from selenium.webdriver.common.keys import Keys 
from selenium.webdriver.common.by import By 
from selenium.webdriver.support import expected_conditions as EC 
from selenium.webdriver.support.ui import WebDriverWait 
from pyvirtualdisplay import Display 


def clear_comments(username, password, words): 
    display = Display(visible=0, size=(1024, 768)) 
    display.start() 
    driver = webdriver.Firefox() 
    driver.get("http://instagram.com") 
    element = WebDriverWait(driver, 3).until(
      EC.presence_of_element_located((By.XPATH, """//*[@id="react-root"]/section/main/article/div[2]/div[2]/p/a""")) 
     ) 
    element.click() 
    u = WebDriverWait(driver, 3).until(
      EC.presence_of_element_located((By.NAME, "username")) 
     ) 
    p = driver.find_element_by_name("password") 

    u.send_keys(username) 
    p.send_keys(password) 
    p.send_keys(Keys.RETURN) 

    #go to photos list 
    element = WebDriverWait(driver, 15).until(
     EC.presence_of_element_located((By.XPATH, """//*[@id="react-root"]/section/nav/div/div/div/div[2]/div[3]/a""")) 
    ) 
    element.click() 

    # click on each photo 
    WebDriverWait(driver, 15).until(
     EC.presence_of_element_located((By.XPATH, """//*[@id="react-root"]/section/main/article/div/div[1]/div[1]/a[1]""")) 
    ) 
    photos = driver.find_elements_by_css_selector('._myci9 > a') 

    for photo in photos: 
     photo.click() 
     comments = WebDriverWait(driver, 15).until(
      EC.presence_of_element_located((By.XPATH, """/html/body/div[2]/div/div[2]/div/article/div[2]/ul""")) 
     ) 

     comments_list = comments.find_elements_by_css_selector('li') 
     for comment in comments_list[1:]: 
      for word in words: 
       if word in comment.text: 
        comment.find_element_by_css_selector('button').click() 
        driver.find_element_by_xpath("""/html/body/div[3]/div/div[2]/div/div/ul[1]/li/button""").click() 
     driver.find_element_by_class_name("_3eajp").click() 

    driver.close() 
    display.stop() 

Он отлично работает на моем проявочной машине, но развертывается версия возвращает следующий отслеживающий:

Ubuntu 14.04.4 (сервер) Firefox 29.0.1 Selenium 2.39.0

Как это исправить?

Answer 1

Это, вероятно, происходит потому, что ожидаемое условие

EC.presence_of_element_located 

возвращает более одного элемента.

Попробуйте сузить область поиска таким образом, чтобы это условие возвращало только один элемент. Я получал ту же ошибку, и это сработало для меня. Там нет много документации о ЕС, но эта ссылка может помочь вам
