Fails to build on 18.04

[popey]

I'm trying to build a snap of rx, on an Ubuntu 18.04 system. Using rust nightly, it fails to build as below. Any ideas what I can do here?

Hmm this looks like somehow there's a mismatch between the rx code you have checked out, and the rgx version it's depending on. Not sure why this is happening.. maybe you need to use --locked to use the Cargo.lock versions. I can perhaps help more if you show me what command you are running, and what version of the code you have checked out.
