ipython - "cannot import name 'create_prompt_application' from 'prompt_toolkit.shortcuts'

I'm trying to get ipython working on my windows 10 64 bit computer. When I try to start ipython from the command line, I get the error pictured in the screenshot attached to this question.

Has anyone encountered this? How I might I fix this problem?

For those of us who get an error

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
mssql-cli 1.0.0 requires click<7.1,>=4.1, but you have click 8.1.3 which is incompatible.
mssql-cli 1.0.0 requires prompt-toolkit<2.1.0,>=2.0.0, but you have prompt-toolkit 3.0.38 which is incompatible.

or get this error

ImportError: cannot import name 'KeyPressEvent' from 'prompt_toolkit.key_binding' (/home/olaf/.local/lib/python3.10/site-packages/prompt_toolkit/key_binding/__init__.py)
   (file "/home/olaf/.local/lib/python3.10/site-packages/IPython/terminal/shortcuts/auto_match.py", line 8, in <module>)

to avoid breaking existing python package version setup just create a new python virtual environment

pip install virtualenv                  #  install package which can create new virt environments
python -m virtualenv venv_this_example  #  create virt environment
source venv_this_example/bin/activate   #  engage virt env
pip3 install 'prompt-toolkit<2.0.0,>=1.0.15' --force-reinstall # issue python package install command which only impacts this specific virt env and not entire host box python package install ecosystem

notice in above it create new directory

venv_this_example/bin/activate

which isolates python packages installed to ONLY effecting this specific virt env

You have to run

pip install --user ipython

to make it work if your user does not have admin rights.

This can also be a solution 

pip3 install --upgrade ipython

if you are working with python3. Or,

pip3 install ipython

This solves some problems of missing kernel to, at least on Linux.

In my case there was an old installation of IPython when I installed juptyer. So pip install -U ipython.

I had the same issue using conda to set virtual environment with a default python version (Python 3.6.4).

Creating the conda environment and forcing any specific python version (even the same version as the problematic default):

conda create -n test_env python=3.6.4

solved it.

You can just reinstall the ipython, that will solve the 'prompt-toolkit' problem automatically.

pip install ipython

This problem is caused by having a newer version of Prompt Toolkit installed than is depended upon by IPython. (Version 2.0.4 of Prompt Toolkit is installed and IPython requires version 1.0.15.)

You can rectify this issue by installing an older, compatible version of prompt-toolkit with pip (or pip3):

pip3 install 'prompt-toolkit<2.0.0,>=1.0.15' --force-reinstall

(If you install or upgrade Prompt Toolkit past 1.0.15—the last 1.x version—you will receive a warning from pip: ipython 6.5.0 has requirement prompt-toolkit<2.0.0,>=1.0.15, but you'll have prompt-toolkit 2.0.4 which is incompatible.)
