I have performed the Troubleshooting steps for Amazon Linux and re-run the `bundled_installer` which generated the attached output. [inst.txt](https://github.com/aws/aws-elastic-beanstalk-cli-setup/files/5170627/inst.txt)

I am unfamiliar with python virtual environments but it appears the `.pyenv/versions/3.7.2/bin/python` is not built with `ncurses` support.

Start by reviewing the bundled_installer output in inst.txt and reproducing the _curses import failure with the Python 3.7.2 environment used by eb appversion. Done means the installed EB CLI can run eb appversion without the ModuleNotFoundError on Amazon Linux 2.
