rubyenv install hangs when linuxbrew command is in PATH and ${HOME}/.linuxbrew does not exist

Installing 2.6.2 hangs on Installing ruby-2.6.2...

$ rubyenv install 2.6.2
Downloading ruby-2.6.2.tar.bz2...
-> https://cache.ruby-lang.org/pub/ruby/2.6/ruby-2.6.2.tar.bz2
Installing ruby-2.6.2...

My uninstalling the linuxbrew-wrapper package helped me fix the problem.

I think what is happening is that, for whatever reason, linuxbrew is invoked when it is found in the PATH, but if the user has never run linuxbrew before (ie the .linuxbrew directory does not exist in HOME), then linuxbrew asks a question and expects an answer on STDIN. Since rubyenv does not echo anything to the end-user beyond Installing ruby-..., the user has no idea that something is asked of him, will wait, and eventually cancel the command.

Could potentially be fixed alongside with #7
