pyenv-suffix is a pyenv plugin which allows you to specify a 'version name suffix' when installing python.

Out of the box, pyenv does not allow you to install multiple copies of the same python version. This can be limiting in situations where you want to have different instances of python with, for example, different compile-time configurations or under different architectures.

pyenv-suffix is forked and adapted from pyenv-alias.

git clone https://github.com/AdrianDAlessandro/pyenv-suffix.git $(pyenv root)/plugins/pyenv-suffix

Specify the version suffix name using the PYENV_VERSION_SUFFIX environment variable when performing a pyenv install

For example, building a version of python 3.10.9 for ARM64 architecture (assuming you're running pyenv appropriately installed in an ARM64 terminal):

PYENV_VERSION_SUFFIX="arm64" pyenv install 3.10.9

Will install a version of python labelled 3.10.9arm64. Which will be listed under your installed versions of python with pyenv when running pyenv versions.

Note: if you are installing a version number that already exists, you will be asked to confirm if you want to install it, this is fine.
