Compile fails on latest rust 1.28

[Aario]

With stable rust one of dependencies named pear won't compile as it needs nightly version.
With nightly rust (1.28) one of dependencies named diesel won't compile as it needs stable version!

error: Could not compile `diesel`.

Already reported it to diesel, but they expect a bug report to be around stable rust (As in their checkboxes in their issue template):
diesel-rs/diesel#1730

This is a known issue with nightly. You can get everything to work by using the following build:

rustup default nightly-2018-05-14.

That is the last known version working for Diesel_CLI and works with rest of app.
