我想重新开始定期使用 Python，特别是用于网页抓取。我使用 Homebrew 安装了 pipenv，并开始安装请求和 BeautifulSoup，但当我尝试导入 BeautifulSoup 时，出现以下错误：
soupsieve package is not installed. CSS selectors cannot be used. 'The soupsieve package is not installed. CSS selectors cannot be used.' Traceback (most recent call last): File "/Users/<user>/.local/share/virtualenvs/virtualenvs-fRlH5dZt/lib/python3.7/site-packages/test.py", line 1, in <module> from bs4 import BeautifulSoup4 File "/Users/<user>/.local/share/virtualenvs/virtualenvs-fRlH5dZt/lib/python3.7/site-packages/bs4/__init__.py", line 34, in <module> from .builder import builder_registry, ParserRejectedMarkup File "/Users/<user>/.local/share/virtualenvs/virtualenvs-fRlH5dZt/lib/python3.7/site-packages/bs4/builder/__init__.py", line 7, in <module> from bs4.element import ( File "/Users/<user>/.local/share/virtualenvs/virtualenvs-fRlH5dZt/lib/python3.7/site-packages/bs4/element.py", line 19, in <module> from bs4.formatter import ( File "/Users/<user>/.local/share/virtualenvs/virtualenvs-fRlH5dZt/lib/python3.7/site-packages/bs4/formatter.py", line 1, in <module> from bs4.dammit import EntitySubstitution File "/Users/<user>/.local/share/virtualenvs/virtualenvs-fRlH5dZt/lib/python3.7/site-packages/bs4/dammit.py", line 13, in <module> from html.entities import codepoint2name ImportError: No module named html.entities [Finished in 0.1s with exit code 1]
有人知道问题是什么吗？html.entities 应该附带 Python3，因此应该可用。
