Cleaning up...

Storing debug log for failure in /home/mounarajan/.pip/pip.log

How can I install this module?

回答1:

urllib.request is only available in python3 branch. See the following post for more info. urllib.request in Python 2.7

回答2:

In python3 you must use urllib3 module.

$ pip3 install urllib3

Or if you're using a virtual env:

$ pip install urllib3

回答3:

In python 2 ,you simply use urllib for example

import urllib
htmlfile=urllib.urlopen("your url")
htmltext=htmlfile.read()

in python 3,you need to use urllib.request

import urllib.request
htmlfile=urllib.request.urlopen("your url")
htmltext=htmlfile.read()

回答4:

For Python3 in cmd,

pip install urllib3

Or if you're using a anaconda:

conda install urllib3

Hope, this will help you
