diesel_cli installation is crashing

[defyrlt]

I've tried to follow the getting started guide and it's crashing on the diesel_cli installation step:

To learn more, run the command again with --verbose.

It looks like our build is failing on the most recent nightly as well, I'll look into it. In the meantime, it should work on nightly-2016-01-23 or older, or beta/stable, so you could switch to one of those for now

[sgrif]

Oh yay, we're failing on nightly for obscure reasons again! >_>

Yeah, as @mcasper mentioned, try switching to an older nightly. Assuming you're using multirust, run

multirust update nightly-2016-02-09
multirust default nightly-2016-02-09

I'll get us working on the latest nightly soon.

Looks like this was caused by rust-lang/rust#31487. I'll push up a fix as soon as I can (we need to synchronize dependencies for syntex versions), but I won't be doing a release for this change.

I've updated the website to include a note about this. Thank you for bringing it to our attention, @defyrlt
