Install Python

SNAFU installs a Python version with a single command. To install <version> on you machine: [1]

snafu install <version>
[1]Use snafu list --all to find out what versions are available. See List Pythons for more information about the list command.

This automatically downloads the installer, and runs it with minimal user input possible. [2] If there’s need to install without Internet connection, you can download the installer yourself, and run:

snafu install --file=path\to\installer.exe <version>

to install directly from that installer. Either way, SNAFU sets up the Python installation on its own, and let you start using it right away.

[2]Generally only to confirm the UAC dialog, if needed.

SNAFU provides some extra executables for you. Say you have install Python 3.6 after you set up SNAFU. Now you can launch Python with:


Install a package, say, Pipenv, with:

pip3 install pipenv

and have the pipenv command available immediately after.

Upgrade Python

SNAFU allows you to upgrade a Python installation to a newer micro version, e.g. 3.6.3 to 3.6.4. Run the following command to upgrade an installed version (if available):

snafu upgrade <version>

It takes some time for the developers to update the definition to a newer version. If you find a newer version released on that is not available in SNAFU, send a pull request to update the definition files!

Uninstall Python

You probably guessed it:

snafu uninstall <version>

Similar to installing, this does nothing too fancy, but just runs the standard uninstaller. It does perform some additional cleanup if you are using the version. See :ref:manage about how you can manage/use versions.
