PyCharm无法导入BeautifulSoup

我试图在Python上使用bs4制作一个蜘蛛,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,就会出错:

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

Process finished with exit code 1

但是在cmd提示符中没有出现此错误:

项目翻译:

您调用了脚本C:/PyCharm Project/bs4.py",from bs4 import BeautifulSoup实际上是在尝试BeautifulSoup从您自己的脚本而不是bs4lib 导入,因此您需要重命名它并删除.pyc目录中的任何文件.
