Question

有一个脚本可以通过关键字从Instagram清除评论：

# 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()

它在我的开发机器上运行正常但部署版本返回下一个回溯：

如何解决？

Answer 1

这可能是因为您的预期情况

EC.presence_of_element_located

返回多个元素。

尝试缩小搜索范围，以便条件只返回一个元素。我得到了同样的错误，这对我有用。没有太多关于EC的文档，但此链接可能对您有所帮助

Selenium在生产时出现BadStatusLine错误。顺利进行调试
