我试图在Python上使用bs4创建一个spider，我已经使用pip和easy_install安装了bs4，但是一旦我使用PyCharm运行程序，就会出现一个错误：

Traceback (most recent call last):
  File "C:/PyCharm Project/bs4.py", line 3, in <module>
    from bs4 import BeautifulSoup
  File "C:\PyCharm Project\bs4.py", line 3, in <module>
    from bs4 import BeautifulSoup
ImportError: cannot import name 'BeautifulSoup'

Process finished with exit code 1

但在命令提示符下，不会出现此错误：

C:\WINDOWS\system32>python

>>> from bs4 import BeautifulSoup

>>> html_doc = """

... <body>
... <p class="title"><b>The Dormouse's story</b></p>
...
... <p class="story">Once upon a time there were three little sisters; and their names were

... and they lived at the bottom of a well.</p>
...
... <p class="story">...</p>
... """
>>>
>>> # create a bs object using a HTML page
... soup = BeautifulSoup(html_doc, 'html.parser', from_encoding='utf-8')
>>> soup.title
<title>The Dormouse's story</title>
>>> soup.title.string
"The Dormouse's story"
>>>

很有可能pycharm被配置为使用python2.7。。。您可以在“文件”>；“设置”>；“项目设置”>；“解释程序”下更改为3.5

或者

在文件顶部键入import bs4。。。当它用红色下划线时，将光标移到它下面。。。按alt+enter，然后选择“安装包bs4”

您用from bs4 import BeautifulSoup调用了脚本C:/PyCharm Project/bs4.py"，实际上您试图从自己的脚本而不是bs4库导入BeautifulSoup，因此需要重命名它并删除目录中的任何.pyc文件。

您应该重新安装它，或者将解释器更改为python 3.5或在文件顶部键入import bs4
