“错误：selenium.common.exceptions.NoSuchElementException：消息

Question

I'm encountering an error NoSuchElementException .

Here is my code:

from time import sleep
from selenium import webdriver


browser = webdriver.Firefox()
browser.implicitly_wait(5)

browser.get('https://www.instagram.com/')

login_link = browser.find_element_by_xpath("//a[text()='log In']")
login_link.click()

sleep(2)

username_input = browser.find_element_by_css_selector("input[name='username']")
password_input = browser.find_element_by_css_selector("input[name='password']")

username_input.send_keys("<your username>")
password_input.send_keys("<your password>")

login_button = browser.find_element_by_xpath("//button[@type='submit']")
login_button.click()

sleep(5)

browser.close()

Answer 1

Just tested this and it seems that this step

login_link = browser.find_element_by_xpath("//a[text()='log In']")
login_link.click()

sleep(2)

is unnecessary. Going to https://www.instagram.com/ sends you straight to the login page on a fresh browser instance.
