python - 导入 beautifulsoup 时出错

Question

我在导入 bs4 时遇到奇怪的错误。我在其他地方找不到任何帮助。我尝试安装 html 和 future。

完整的回溯:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Python27\lib\site-packages\bs4\__init__.py", line 35, in <module>
    from .builder import builder_registry, ParserRejectedMarkup
  File "C:\Python27\lib\site-packages\bs4\builder\__init__.py", line 7, in <module>
    from bs4.element import (
  File "C:\Python27\lib\site-packages\bs4\element.py", line 10, in <module>
    from bs4.dammit import EntitySubstitution
  File "C:\Python27\lib\site-packages\bs4\dammit.py", line 53, in <module>
    class EntitySubstitution(object):
  File "C:\Python27\lib\site-packages\bs4\dammit.py", line 74, in EntitySubstitution
    CHARACTER_TO_HTML_ENTITY_RE) = _populate_class_variables()
  File "C:\Python27\lib\site-packages\bs4\dammit.py", line 62, in _populate_clas

    character = chr(codepoint)
ValueError: chr() arg not in range(256)

Answer 1

1. 试试这个

     from bs4 import BeautifulSoup    
   

   也适用于 python3 和 BS 4

2. 或者也许这有帮助:

    from bs4 import BeautifulSoup as bs
    import urllib
    url="http://example.com"
    soup = bs(urllib.urlopen(url))
    for link in soup.findAll('a'):
    print link.string
   

   要获取标签的任何数据，只需将“a”替换为您想要的标签

3. 交叉检查文件名是否命名为“bs4.py”或者类似“HTMLParser.py”的名称
