我使用pip3 install beautifulsoup下载了BeautifulSoup，但效果很好。
但是当我尝试from bs4 import BeautifulSoup或import BeautifulSoup时，我会收到错误ModuleNotFoundError: No module named 'BeautifulSoup'或ModuleNotFoundError: No module named 'bs4'，具体取决于我使用的代码行。
我不知道出了什么问题。为什么我会收到错误？

pip3 install beautifulsoup会安装BeautifulSoup旧版本（准确地说是Beautiful Soup 3）。
您需要pip3 install beautifulsoup4或pip3 install bs4来安装BeautifulSoup4
然后你可以像这样使用它：
from bs4 import BeautifulSoup
您可以参考Beautiful Soup的{{3}}和download page了解更多信息。

I had the same problem and what solved it for me was to upgrade pip3.
Try this from this thread comment
pip3 install --upgrade pip
And if that does not work, there is another way to upgrade it that I found from this post
curl https://bootstrap.pypa.io/get-pip.py | python3
