Python error importing dateutil

Question

I try to execute marathon-lb.py and it throws the next error:

Traceback (most recent call last):
  File "./marathon_lb.py", line 46, in <module>
    import dateutil.parser
ImportError: No module named 'dateutil'

I just install python with apt and with pip. I have run:

sudo apt-get install python-pip
pip install python-dateutil

I compile the script with: python -m py_compile script.py

python application:

from operator import attrgetter
from shutil import move
from tempfile import mkstemp
from wsgiref.simple_server import make_server
from six.moves.urllib import parse
from itertools import cycle
from common import *
from config import *
from lrucache import *
from utils import *

import argparse
import json
import logging
import os
import os.path
import stat
import re
import requests
import shlex
import subprocess
import sys
import time
import dateutil.parser

What happens when you run `import dateutil` in Python terminal? — Bubble Hacker, May 25 '16 at 11:00
I have a feeling when it is compiled it is not able to compile the `dateutil` module. I will update when I confirm this... — Bubble Hacker, May 25 '16 at 11:12
Let's add some methodology here. First, install a virtualenv and see if it is possible. I believe you may not have some basic c++ compilers that Python requires for installing some packages. This problem will be more evident when you try to install a virtuanelv. — Ricardo Silveira, May 25 '16 at 11:58
I execute `sudo apt-get install virtualenv` and the packet is not found @RicardoSilveira — Asier Gomez, May 26 '16 at 07:27
So, the python terminal imports fine, but your script does not? Are you running different versions of python? — OneCricketeer, May 26 '16 at 07:32
How can I verify if I am running different versions of python? @cricket_007 — Asier Gomez, May 26 '16 at 07:34
@Asier Run `python -V`, and also `pip -V` to check the version of pip, there are two different pip for python2 and 3. — Gary Sham, May 26 '16 at 07:38
I have pip 1.5.4 (python 2.7) and Python 2.7.6 its fine? @GarySham — Asier Gomez, May 26 '16 at 07:41

does this statement runs on python shell `import dateutil.parser` ? – Tanu May 25 '16 at 11:08
Yes it runs on python shell – Asier Gomez May 26 '16 at 07:25
So is it still giving error when you try to compile script? – Tanu May 26 '16 at 07:27

There are probably multiple versions of `python-dateutil` installed. Try to issue `pip uninstall python-dateutil` several times until the prompt says there is no `python-dateutil` installed. Then, you can issue `pip install python-dateutil` again. That solves my problem. – xxks-kkk Nov 05 '17 at 06:32

Step 1. First thing is upgrade pip for corresponding python version (3 or 2) you have.

pip3 install --upgrade pip

or

pip2 install --upgrade pip

Step2.

Some times directly running command wont work since

There are probably multiple versions of python-dateutil installed.

Try to run pip uninstall python-dateutil

will give below message if python-dateutil is already un installed.

Cannot uninstall requirement python-dateutil, not installed

Then, you can run pip install python-dateutil again.

Step2.

NOTE : Directly running step2 wont work for users whose python and pip versions are not compatible.
