# Import requiements

# Create our class
class InstagramBot:
    def __init__(self, username, password):
        self.username = username
        self.password = password
        self.bot = webdriver.Firefox(executable_path = '/Users/dragos/Downloads/geckodriver')   

    # Function will log us in to Instagram
    def login(self):
        bot = self.bot
        # Navigate to the Instagram login page
        bot.get('https://www.instagram.com/accounts/login/')
        time.sleep(3)

        # Find the email and password boxes, enter our login credentials
        email = bot.find_element_by_name('username').send_keys(self.username)
        password = bot.find_element_by_name('password').send_keys(self.password)

        # Wait for 1 second then press ENTER
        time.sleep(1)
        bot.find_element_by_name('password').send_keys(Keys.RETURN)

        # Wait 3 second while the post-login page loads
        time.sleep(3)

    def findMyFollowers(self, number_of_followers):
        bot = self.bot

        bot.get('https://instagram.com/' + self.username)
        time.sleep(2)

        bot.find_element_by_xpath('//a[@href="/' + self.username + '/followers/"]').click()

        time.sleep(1)

        popup = bot.find_element_by_class_name('isgrP')

        followers_array = []

        i = 1

        while len(followers_array) <= number_of_followers:
            bot.execute_script('arguments[0].scrollTop = arguments[0].scrollHeight', popup)
            time.sleep(0.4)

            followers = bot.find_elements_by_class_name('FPmhX')

            for follower in followers:
                if follower not in followers_array:
                    followers_array.append(follower.text)

            i+=1

        print(followers_array)

        self.followers = followers_array

    def followTheirFollowers(self, number_to_follow):
        bot = self.bot

        for follower in self.followers:
            bot.get('https://instagram.com/' + follower)
            time.sleep(2)

            if(len(bot.find_elements_by_xpath("//*[contains(text(), 'This Account is Private')]")) > 0):
                # If they're private, we can't see their follower list, so skip them
                continue

            bot.find_element_by_xpath('//a[@href="/' + follower + '/followers/"]').click()
            time.sleep(3)

            follow = bot.find_elements_by_xpath("//button[contains(text(), 'Follow')]")

            i = 1

            for follower in follow:
                if(i != 1):
                    bot.execute_script("arguments[0].click();", follower)

                if(i > number_to_follow):
                    break

                i+=1

            time.sleep(2)


insta = InstagramBot('Username(here I put my username)', 'Password(and here password)')
insta.login()
insta.findMyFollowers(5)
insta.followTheirFollowers(10)

    

这里是错误

我不知道如何解决，我的课需要这个，我需要这个非常快。如果你想了解更多细节，请说你想打磨什么 我使用 python 启动器运行此代码，什么时候启动 Firefox 我有这个错误，我知道如何解决
