The first two error messages appear because of an oversight in the rendy crate which still depends on an outdated version of rendy-mesh (0.3.0) instead of the correct version (0.3.1). This probably needs a rerelease of the rendy crate to fix.
Refer to https://github.com/amethyst/amethyst/issues/1819#issuecomment-514708470 instead.

The third error is because your rust installation is outdated. To update use rustup update.

Simple cargo update will fix the first issue

After rustup update and cargo update, it works. Thanks @Friz64 and @omni-viral !
