求助各路大佬，beautifulsoup运行报错'HTMLParserTreeBuilder' object has no attribute 'initialize_soup'

Question

import requests
from bs4 import BeautifulSoup
import bs4

def getHTMLText(url):
    try:
        r = requests.get(url, timeout=30)
        r.raise_for_status()
        r.encoding = r.apparent_encoding
        return r.text
    except:
        return '产生错误'                

def fillUnivList(ulist, html):
    soup = BeautifulSoup(html, "html.parser")
    for tr in soup.find('tbody').children:
        if isinstance(tr, bs4.element.Tag):
            tds = tr('td')
            ulist.append([tds[0].string, tds[1].string, tds[2].string])

def printUnivList(ulist, name):
    tplt = "{0:^10}\t{1:{3}^10}\t{2:^10}"
    print(tplt.format('排名','学校名称','省市',chr(12288)))
    for i in range(len(ulist)):
        u = ulist[i]
        if u[2]==name:
            print(tplt.format(u[0], u[1], u[2],chr(12288)))

def main():
    uinfo = []
    url = "http://www.zuihaodaxue.cn/zuihaodaxuepaiming2019.html"
    html = getHTMLText(url)
    fillUnivList(uinfo, html)
    name = input().strip()
    printUnivList(uinfo, name)
main()

以上是爬取最好大学排名，spyder显示以下错误：

File "D:\mydata\anoconda\lib\site-packages\bs4__init__.py", line 283, in init
self.builder.initialize_soup(self)

AttributeError: 'HTMLParserTreeBuilder' object has no attribute 'initialize_soup'

我打开_htmlparser.py发现HTMLParserTreeBuilder确实没有nitialize_soup'，但不知道怎么修改，也不确定是否在此文件改不敢下手，还望大神相助，指点下，要不作业完成不都了啦▽〒
