Cannot switch project to one using TRAMP

[chy-causer]

Expected behavior

Switching project to a TRAMP one should switch the project

Actual behavior

I get the error "You're not in a project". I believe there was a recent fix to projectile to fix TRAMP issues. Projectile now works great but I think there's something here too that needs something changed. Forgive my vagueness as I am very new to Emacs.

Steps to reproduce the problem

C-p p => select a project that is using TRAMP. Disabling helm-projectile allows projectile to select the project fine using the minibuffer.

It seems to me that this error is coming from help-projectile, as there's no such check in Projectile itself. I'll check if it's an easy fix.

Thanks. I believe the line is https://github.com/bbatsov/helm-projectile/blob/master/helm-projectile.el#L754

There is a tantalizing not-require-root variable in that macro, but I don't know enough about the project to comment any further on it.

I think the project check fails for TRAMP, unless you're already connected, so probably it needs something like https://github.com/bbatsov/projectile/commit/c8b71639300da597ac24994b22e4ac81f2c34f5e
