Autojump fails when starting from a directory with a .python-version file

[tylucaskelley]

Description

Ran into an interesting issue when trying to use autojump. When starting in a directory that contains a .python-version file, which the tool pyenv uses to set a local Python version, autojump will fail if said version is not installed. Here's the error I get:

$ j down

pyenv: version `3.8.3' is not installed (set by /Users/tylucaskelley/Code/validation-service/.python-version)
autojump: directory 'down' not found
\n\n
Try `autojump --help` for more information.

If I remove the .python-version file, the issue goes away. The reason why that local version isn't installed is because I'm using the Poetry package management tool for my Python projects, so I don't actually need to install that version on my system globally.

Reproducing

Here's a minimal way to reproduce the issue (assuming autojump already installed)

1. Install pyenv on the system
2. Create a directory with a .python-version file in it, and set to a Python version not installed on the system
3. Go to said directory, and try to use autojump to leave - should get the same error I did above

System info

• macOS 10.15.5
• autojump installed via Homebrew
• System has pyenv installed
• Using iTerm 2

This won't be the case if autojump is not implemented in a interpreted language like Python. So I've created a project to rewrite it in Go, you may want to give it a try: https://github.com/suzaku/shonenjump

I found an easy solution here.
Basically, you just need to copy the 4 .py files from your system python (/usr...): autojump_argparse, autojump_data, autojump_match, autojump_utils to the corresponding version in .pyenv.
