ImportError: No module named 'prometheus.client'

I am currently trying to run a sample code I code off of the internet.

While trying to run it using python2.7, I get the following ERROR :

# python2.7 example.py 
Traceback (most recent call last):
  File "example.py", line 9, in <module>
    from http.server import HTTPServer
ImportError: No module named http.server

I tried to run the following :

# pip install http.server
Collecting http.server
  Could not find a version that satisfies the requirement http.server (from versions: )
No matching distribution found for http.server

But when I use python3, it does not give me the ERROR. Rather gives the ERROR :

# python3 example.py 
Traceback (most recent call last):
  File "example.py", line 13, in <module>
    from prometheus.client import Gauge
ImportError: No module named 'prometheus.client'

Im trying to install prometheus.client using pip and pip3 but nothing.

# pip install prometheus.collectors
Collecting prometheus.collectors
  Could not find a version that satisfies the requirement prometheus.collectors (from versions: )
No matching distribution found for prometheus.collectors

# pip3 install prometheus.collectors
Collecting prometheus.collectors
  Could not find a version that satisfies the requirement prometheus.collectors (from versions: )
No matching distribution found for prometheus.collectors

How can I get the missing libraries ?

EDIT ::

In the below example I am using a very minimalist approach (again from github)

from prometheus_client import start_http_server, Summary
import random
import time

# Create a metric to track time spent and requests made.
REQUEST_TIME = Summary('request_processing_seconds', 'Time spent processing request')

# Decorate function with metric.
@REQUEST_TIME.time()
def process_request(t):
    """A dummy function that takes some time."""
    time.sleep(t)

if __name__ == '__main__':
    # Start up the server to expose the metrics.
    start_http_server(8000)
    # Generate some requests.
    while True:
        process_request(random.random())

Running the above code yields :

# python3.4 main.yaml 
Traceback (most recent call last):
  File "main.yaml", line 1, in <module>
    from prometheus_client import start_http_server, Summary
ImportError: No module named 'prometheus_client'

Whereas I do have the library installed. 

# pip3 install prometheus_client
Requirement already satisfied: prometheus_client in /usr/lib/python2.7/site-packages

I had already installed prometheus_client==0.21.0, but faced same error.

Downgrading to prometheus_client==0.20.0 worked for me:

pip3 install prometheus_client==0.20.0

I faced the exact same problem. I installed pip3 using python3 -m pip install --upgrade pip. After that ran pip3 install prometheus_client. After this, the issue got fixed.

I'm running on ubuntu 18.10 and i got the same issue, and i have python2 install already. I was able to solved it by installing python3 and python3-pip like below.

sudo apt install python3
sudo apt install python3-pip
pip3 install prometheus_client

May be helpful to somebody!

http.server is a module in Python 3.

See the note for SimpleHTTPServer in Python 2:

Note The SimpleHTTPServer module has been merged into http.server in Python 3. The 2to3 tool will automatically adapt imports when converting your sources to Python 3.

For prometheus.client, you want pip install prometheus_client. See https://github.com/prometheus/client_python

README.md from the repository you linked states:

Deprecated, use: https://github.com/prometheus/client_python
