导入错误由于BS4 VS BeautifulSoup

问题描述

我想使用 beautifulsoup 兼容 LXML ，这是给我的错误：

I am trying to use beautifulsoup compatible lxml and it is giving me an error:

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。我该如何解决这个问题？

I have bs4 installed. How do I fix this issue?

推荐答案

该错误是由 soupparser.py 试图引起的，而你有版本4安装导入BeautifulSoup 3版。该模块的名字从 BeautifulSoup 4版改为 BS4 。

The error is caused by soupparser.py trying to import BeautifulSoup version 3 while you have version 4 installed. The module name was changed from BeautifulSoup to bs4 in version 4.

您可以欺骗 soupparser.py 到由 BS4 模块映射到 BeautifulSoup sys.modules中 soupparser C $ C> 导入前：

You can trick soupparser.py into importing version 4 by mapping the bs4 module to BeautifulSoup in sys.modules before importing soupparser:

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

from lxml.html.soupparser import fromstring
