for link in links:

print u'获取lacie的链接'
link_node = soup.find('a',href='http://example.com/lacie')
print link_node.name,link_node['href'],link_node.get_text()
print u'正则匹配'
link_node = soup.find('a',href=re.compile(r"ill"))
print link_node.name,link_node['href'],link_node.get_text()前面都还好 当进行正则匹配的时候
有如下提示
正则匹配
Traceback (most recent call last):

link_node = soup.find('a',href=re.compile(r"ill"))

请问如何解决？
