由于bs4与BeautifulSoup导致导入错误

Question

我试图使用beautifulsoup兼容lxml,它给了我一个错误:

from lxml.html.soupparser import fromstring
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Python/2.7/site-packages/lxml/html/soupparser.py", line 7, in <module>
    from BeautifulSoup import \
ImportError: No module named BeautifulSoup

我bs4安装了.我该如何解决这个问题？

Answer 1

soupparser.py安装版本4时尝试导入BeautifulSoup版本3 会导致该错误.模块名称已从版本4 更改BeautifulSoup为bs4.

您可以soupparser.py通过在导入之前将bs4模块映射到BeautifulSoupin 来欺骗导入版本4 :sys.modulessoupparser

import sys, bs4
sys.modules['BeautifulSoup'] = bs4

from lxml.html.soupparser import fromstring
