报错No handlers could be found for logger "bs4.dammit"
运行代码时报错：No handlers could be found for logger "bs4.dammit"
# coding:utf8
import urllib2
import bs4
import re
url = 'http://www.baidu.com'
request = urllib2.Request(url)
request.add_header('user-agent', 'Mozilla/5.0')
response = urllib2.urlopen(request)
html_doc = response.read()
soup = bs4.BeautifulSoup(html_doc, 'html.parser', from_encoding='utf-8')
links = soup.find_all('a')
link = soup.find('a', href=re.compile(r".*preferences.*"))
print link.name, link['href'], link.get_text()这个代码运行时而可以成功运行，时而报上述错误。不能运行的时候等两分钟再运行又可以成功输出了。
