import httplib ImportError：没有名为httplib的模块

Question

运行test.py

时出现此错误

C:\Python32>python.exe test.py
Traceback (most recent call last):
  File "test.py", line 5, in <module>
    import httplib
ImportError: No module named httplib

如何纠正？

test.py 的代码块：

#!/usr/local/bin/python

import httplib
import sys
import re
from HTMLParser import HTMLParser


class miniHTMLParser( HTMLParser ):

  viewedQueue = []
  instQueue = []

  def get_next_link( self ):
    if self.instQueue == []:
      return ''
    else:
      return self.instQueue.pop(0)


  def gethtmlfile( self, site, page ):
    try:
      httpconn = httplib.HTTPConnection(site)
      httpconn.request("GET", page)
      resp = httpconn.getresponse()
      resppage = resp.read()
    except:
      resppage = ""

    return resppage


  def handle_starttag( self, tag, attrs ):
    if tag == 'a':
      newstr = str(attrs[0][1])
      if re.search('http', newstr) == None:

              print ("  adding", newstr)
              self.instQueue.append( newstr )
              self.viewedQueue.append( newstr )
          else:

        else:
          print ("  ignoring", newstr)
      else:

    sys.exit(2)

  mySpider = miniHTMLParser()

  link = sys.argv[2]

  while link != '':

    print ("\nChecking link ", link)

    # Get the file from the site and link
    retfile = mySpider.gethtmlfile( sys.argv[1], link )

    mySpider.feed(retfile)

    # Search the retfile here

    link = mySpider.get_next_link()

  mySpider.close()

Answer 1

您正在Python 3上运行Python 2代码。在Python 3中，该模块已重命名为http.client。

您可以尝试在代码上运行2to3 tool，并尝试自动翻译。对httplib的引用将自动重写，以改为使用http.client。

Answer 2

当我尝试缩小Docker容器时遇到了这个问题。这是因为我用以下命令安装了Python 2.7：

apt-get install -y --no-install-recommends python

我不应该包含--no-install-recommends标志：

apt-get install -y python

Answer 3

如果您使用PyCharm，请将“项目解释器”更改为“ 2.7.x”

Answer 4

您可以使用以下代码导入 http.client 并将其重命名为 httplib ：

将 http.client 导入为 httplib
