I am unable to add a remote Ruby SDK for my development Vagrant box.
RubyMine apparently finds and parses my Vagrantfile just fine. I can browse the remote directory structure and locate the ruby command (in /usr/local/rbenv/shims) by using the dialog that pops up when I click the folder icon.
But when I click 'ok' in the final dialog I get an error dialog with the message "Can't create Ruby SDK - Communication Error".
I have previously been able to add a remote interpreter on the same Vagrant box but now it won't work.
