“No module named ipython” error despite already installed

Question

I am trying to launch ipython using the command: python -m ipython

When launched I get the following error : C:\\Program Files\\Python36\\python.exe: No module named ipython

This is strange because when I run python -m pip show ipython , I get the following message :

Name: ipython
Version: 6.2.1
Summary: IPython: Productive Interactive Computing
Home-page: https://ipython.org
Author: The IPython Development Team
Author-email: ipython-dev@python.org
License: BSD
Location: c:\program files\python36\lib\site-packages
Requires: simplegeneric, setuptools, decorator, pickleshare, traitlets,         
pygments, colorama, prompt-toolkit, jedi

I already ensured that all dependencies were correctly installed. Could you please help me ?

Answer 1

It is actually spelled IPython (upper case I and P to start).

python -m IPython

will do.

Edit: confusion can arise because the pypi service allows the package name and module name to differ.

Answer 2

I solved this problem by using below command:

pip install IPython==5.0 --user

IPython version needs to pair with python version, and I have a python2.7
