这个错误是由于无法找到具有选择器 `.rev-total a` 的元素引起的。这可能是因为页面中没有符合该选择器的元素或者元素还没有加载完成。

您可以尝试使用显式等待来等待元素的出现。这样可以确保在元素可见之前等待一段时间，以防止找不到元素的错误。以下是修改后的代码示例：

import time
import openpyxl
from selenium import webdriver
from bs4 import BeautifulSoup
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By

url = "https://www.mafengwo.cn/poi/16790.html"
edge = webdriver.Edge()
edge.get(url)
comments_data = []

# 等待页面加载完成
time.sleep(5)

# 点击展开更多评论按钮
more_btn = WebDriverWait(edge, 10).until(EC.presence_of_element_located((By.CSS_SELECTOR, ".rev-total a")))
edge.execute_script("arguments[0].click();", more_btn)
time.sleep(2)

# 循环获取点评信息
while True:
    # 获取页面源码
    html = edge.page_source
    soup = BeautifulSoup(html, "html.parser")
    
    # 获取每条点评的信息
    reviews = soup.select(".rev-item")

    for review in reviews:
        # 获取点评内容
        content = review.select_one(".rev-txt").get_text().strip()
        print("点评内容:", content)

        # 获取点评时间
        date = review.select_one(".time").get_text().strip()
        print("点评时间:", date)

        # 获取点评用户
        user = review.select_one(".name").get_text().strip()
        print("点评用户:", user)

        # 获取点评评分
        score = review.select_one(".score span").get_text().strip()
        print("点评评分:", score)

        print("-----------------------------")

        comments_data.append([content, date, user, score])

    # 翻页操作
    next_btn = edge.find_element("css selector", ".pg-next")
    if next_btn.get_attribute("class") == "pg-next":
        edge.execute_script("arguments[0].click();", next_btn)
        time.sleep(2)
    else:
        break

# 将爬取的点评信息存入comments.xlsx文件中
wb = openpyxl.Workbook()
ws = wb.active
ws.append(["点评内容", "点评时间", "点评用户", "点评评分"])

for data in comments_data:
    ws.append(data)

wb.save("comments.xlsx")
wb.close()

# 关闭浏览器
edge.quit()

在这个示例中，我使用了显式等待来等待更多评论按钮的出现。`WebDriverWait`类会等待一个特定条件的满足，这里是直到元素可见。`EC.presence_of_element_located`条件表示元素已经在DOM中出现。

希望这次修改能解决问题。如果您有任何其他问题，请随时提问。
