Hands-on Rust: flappy does not compile due to outdates bytemuck

Hands on Rust: Effective Learning through 2D Game Development and Play

Page 48

Cargo.toml file in book:

[package]
name = "hello_bterm"
version = "0.1.0"
authors = ["Herbert Wolverson <herberticus@gmail.com>"]
edition = "2018"
[dependencies]
bracket-lib = "~0.8.1"

When calling cargo run, get the following error:

error: failed to download `bytemuck v1.12.1`

Caused by:
  unable to get packages from source

Caused by:
  failed to parse manifest at `C:\Users\Mike Chambers\.cargo\registry\src\github.com-1ecc6299db9ec823\bytemuck-1.12.1\Cargo.toml`

Caused by:
  feature `resolver` is required

  this Cargo does not support nightly features, but if you
  switch to nightly channel you can add
  `cargo-features = ["resolver"]` to enable this feature

rustup version 1.25.1 and rustc 1.50.0

Is there a specific version of rust we need to use to get this to work?

First Post!

Hi!

That’s a new one, haven’t run into that before! I’ll revisit this tomorrow when I have more time, but in the mean-time here’s two things to try:

Option 1: Lock the revision
Change the bracket-lib dependency to =0.8.1, and then run cargo update. That will force the package to the version that was live when the book released.

Option 2: Update Rust
At your command-line, issue rustup self update and then rustup update. I’m running rustup version 1.6.3 here, which definitely includes the new resolver system.

Hope that helps!
