Hi,

I get an issue when trying to use tfenv on MacOS:

Installation:

$ brew install tfenv
==> Downloading https://github.com/kamatama41/tfenv/archive/v0.6.0.tar.gz
Already downloaded: /Users/*******/Library/Caches/Homebrew/tfenv-0.6.0.tar.gz
🍺  /usr/local/Cellar/tfenv/0.6.0: 19 files, 23.5KB, built in 1 second
$

List remote:

$ tfenv list-remote
0.11.2
0.11.1
0.11.0
0.11.0-rc1
0.11.0-beta1
...
0.1.1
0.1.0

Try to install a version:

$ tfenv install latest
