beautifulsoup()库报错

Question

代码如下：

from bs4 import BeautifulSoup


strt = """
<title>尚学堂</title>
<div class='info' float='left'>Welcome to SXT</div>
<div class='info' float='right'>
    <span>Good Good Study</span>
    <a href='www.bjsxt.cn'></a>
    <strong><!--没用--></strong>
</div>
"""
soup = BeautifulSoup(strt, 'lxml')
print(soup.text)

结果如下：

Traceback (most recent call last):
  File "D:/python_work/爬虫/beautifulsoup的使用.py", line 1, in <module>
    from bs4 import BeautifulSoup
  File "D:\python_work\爬虫\bs4\__init__.py", line 115
    def __init__(self, markup: object = "", features: object = None, builder: object = None,
                 ^
SyntaxError: non-default argument follows default argument

小白一枚，beautifulsoup和 lxml库都已经安装了 网上查了报错说是不带值的形参放到了后面的原因，但是好像与这个没啥关系吧 有没有大佬解答一下

我遇到过这个问题，怎么解决的有点忘记了，pip install beautifulsoup4试试？
