Windows 8
(Powershell)
For best results, uninstall previous versions FIRST (see Uninstalling).
Using Windows 8 or later, it‘s possible to install with one simple Powershell
command. Start up Powershell and paste this command:
> (Invoke-WebRequest https://bootstrap.pypa.io/ez_setup.py).Content | python -
You must start the Powershell with Administrative privileges or you may
choose to install a user-local installation:
> (Invoke-WebRequest https://bootstrap.pypa.io/ez_setup.py).Content | python - --user
If you have Python 3.3 or later, you can use the py command to install to different Python
versions. For example, to install to Python 3.3 if you have Python 2.7
installed:
> (Invoke-WebRequest https://bootstrap.pypa.io/ez_setup.py).Content | py -3 -
The recommended way to install setuptools on Windows is to download ez_setup.py and run it. The
script will download the appropriate .egg file and install it for you.
Once installation is complete, you will find an easy_install program in your Python Scripts
subdirectory. For simple invocation and best results, add this directory
to your PATH environment variable, if it is
not already present. If you did a user-local install, the Scripts
subdirectory is $env:APPDATA\Python\Scripts.
