它不是powershell，而是python脚本。

Python对名​​称区分大小写。

导入的代码BeautifulSoup并使用了beautifulsoup。

import urllib2  
from bs4 import BeautifulSoup  # <--- 
url = 'https://www.crummy.com/software'
user_agent = 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_5)'
headers = {'User-Agent' : user_agent}
request = urllib2.Request(url,headers = headers)
response = urllib2.urlopen(request)
content = response.read()
soup = BeautifulSoup(request)  # <--- FIXED to match case
print soup.body #  <--- FIXED a typo
