        with urllib.request.urlopen(self.base_url) as url:
            html_source = url.read()
        data = html_source#.encode('utf-8')
        parsed_html = BeautifulSoup(data, 'html.parser')

if __name__ == "__main__":
    unittest.main()

当我跑 $python3 test.py

然后尝试

from beautifulsoup4 import BeautifulSoup

文件“test.py”，第 6 行，在 from beautifulsoup4 import …
