I'm trying to upgrade pyenv with homebrew for getting new Python releases.
Here is the problem:
$ brew upgrade pyenv
Error: pyenv 1.2.7 already installed
Is there a kind of update latency in homebrew package versioning? I am aware of the existence of other ways to install pyenv, but I'd like to use homebrew.
pyenv 1.2.8 is not yet officially released.
On the master branch the last tag is 1.2.7.
The commit you mentioned in your question is in preparation for release 1.2.8.
Version 1.2.7 is here https://github.com/pyenv/pyenv/tree/v1.2.7
Version 1.2.8 should be here https://github.com/pyenv/pyenv/tree/v1.2.8 but nothing is there (yet).
