Pyenv Offline Setup

1. Download and transfer pyenv
2. Extract pyenv-x.x.x.tar.gz into ~/.pyenv
3. Add into ~/.zshrc and source

   export PATH=/home/user/.pyenv/bin:$PATH
   eval "$(pyenv init -)"
   eval "$(pyenv virtualenv-init -)"

4. Download and transfer desired python-3.x.x
5. Place Python-3.x.x.tar.zx file in ~/.pyenv/cache (Don't untar)
6. Run pyenv install 3.x.x

Thanks for that!

A few notes to others that come here

• For the first command (export) - you should change it to your current user or can use $USER environment variable

export PATH=/home/$USER/.pyenv/bin:$PATH

• In the last command, pyenv virtualenv-init is a plugin and for latest version today - 2.4.19 - is not installed by default. To use it you will need to install it (not sure how to do it, specifically offline)
• If you don't want to use pyenv by default, don't change your ~/.zshrc. For other shells, change the relevant file (e.g. ~/.bashrc)
• ~/.pyenv/cache does not exist by default - create it with mkdir ~/.pyenv/cache.
• Make sure you download the Python-3.x.x.tar.zx and not other versions that may exist (I initially downloaded .tgz 🤦‍♂️)

@tomercagan pyevn-virtualenv is available here. You can grab a tarball and extract it as explained in its README file(simply by extracting the archive under $(pyenv root)/plugins/.
Alternatively it should also be possible to get rid of the pyenv virtualenv-init step entirely, as it isn't mentioned in the official pyenv shell integration steps.
