python - 导入错误 : No module named bs4?

Question

我尝试导入库:from bs4 import BeautifulSoup。

当我运行脚本时出现错误:

Traceback (most recent call last):
  File "index.py", line 9, in <module>
    from bs4 import BeautifulSoup
ImportError: No module named bs4
root@srvr [/home/public_html/grabber/similar]# 

当我尝试安装时:

pip install beautifulsoup4

我收到以下错误:

Requirement already satisfied: beautifulsoup4 in /usr/lib/python2.6/site-packages/beautifulsoup4-4.5.1-py2.6.egg

脚本是:

import sys
sys.path.append('/usr/lib/python2.6/site-packages')
from bs4 import BeautifulSoup

Answer 1

您安装了适用于 Python 2.6 的 BeautifulSoup，但根据您的标签，您使用的是 Python 3.x。要为 Python 3 显式安装，请使用 pip3 而不是 pip，即

pip3 install beautifulsoup4
