Troubleshooting Python2 Installation of IPyton 'Python2 Install IPYTHON Failed'

IPython is an incredibly useful tool for anyone serious about working with Python code. It offers a powerful and flexible alternative to the standard interpreter that comes bundled with most distributions, providing features like syntax highlighting, completion suggestions, and more.

Despite its many benefits however - including being easy-to-use once installed properly in your environment - some users may encounter issues when trying out IPython themselves during their initial setup process. If you've tried following all of the instructions but still cannot get past this final hurdle here are a few things worth checking before giving up entirely...

1) Ensure You Have The Correct Version Of Python2 Installed

IPython is designed to work with version 2.x or higher of Python, so make sure that's what you have installed on your system. If not, follow the instructions in 'Do not download software from unofficial websites.' to download and install the latest release.

2) Verify Your PATH Environment Variable Is Set Correctly

If IPython still won't install after ensuring you're running with the correct version of Python 2.x, check if $PYTHONPATH (or %PYTHONPATH% on Windows) includes the path where ipython was extracted. You can do this by opening up a terminal or command prompt and typing:

echo $PYTHONPATH

on Unix-like systems or:

set PYTHONPATH

in Command Prompt.

If neither of these paths contains an entry pointing to your local IPython distribution, try adding it manually like so:

export IPYTHONHOME=/path/to/ipthon2

# On Windows:

set IPYTHON_HOME=C:\PathToIPyThon2\

Then retry running the installation command.

3) Check For Conflicts With Other Python Distributions Or Environments

If you have multiple versions of Python or virtual environments like Virtualenv, PyPI (Python Package Index), conda etc. installed on your system there might be conflicts preventing IPython from installing correctly. Try completely removing any existing instances before attempting again:

# On Unix-like systems:

pip uninstall -y --force ipython

python setup.py clean

4) Clean Your Python Environment And Re-Install Everything From Scratch

As a last resort, consider wiping your entire Python environment and starting fresh from scratch using something like virtualenv or venv. This will give you an empty slate free of any potential conflicts or corruptions that might be causing issues during installation.

After following these steps if IPython still refuses to install properly after installing all necessary dependencies manually via pip (or easy_install on older versions), it may indicate a deeper issue with your system's Python setup rather than anything wrong per se with IPYTHON itself. In such cases seeking help from experienced users within relevant forums or mailing lists might prove very beneficial...
