Cannot run in gitpod due to edition2021

When I run this repo in gitpod I witness this error message.

cargo install --force --path .
error: failed to parse manifest at `/workspace/rustlings/Cargo.toml`

Caused by:
  feature `edition2021` is required

  The package requires the Cargo feature called `edition2021`, but that feature is not stabilized in this version of Cargo (1.55.0 (32da73ab1 2021-08-23)).
  Consider trying a newer version of Cargo (this may require the nightly release).

Some other command is needed?

Oh, I figured it would just use the latest stable version of Rust automatically... not sure where that would need to be changed.

They update from time to time, but this one has been skipped :shrug: https://github.com/gitpod-io/workspace-images/pull/554

I'm no longer stuck (see #554) The final step in my work-around was to run

gitpod /workspace/rustling $ ./install.sh

and the output:

   Installed package `rustlings v4.6.0 (/workspace/rustlings/rustlings)` (executable `rustlings`)
Installing the 'cargo-clippy' executable...

All done! Run 'rustlings' to get started.
gitpod /workspace/rustlings $ rustlings

Thanks for installing Rustlings!

@xpat That makes sense, since it pulls from a tag, and the latest release doesn't conform to the 2021 edition yet. I suppose we'll just wait with pushing a new release until Gitpod decides they want to upgrade their Rust toolchain 🤷

Hey folks, Geoff here from Gitpod. We were going to wait for v1.57 which is planned for 02/12 due to reports of drastically increased/endless compile times (due to the switch to a new llvm version). In response to CVE-2021-42574 we are upgrading the default image to v1.56.1. As a reminder one can bring their own Dockerfile to Gitpod and run nearly anything on the platform including operating systems.

[manyinsects]

@ghuntley Thanks for the clarification! I think waiting should be fine, unless someone wants to take time to write a Dockerfile.

[ghuntley]

v1.56.1 is now available on Gitpod in the default workspace image.

gitpod /workspace/new $ rustc --version
rustc 1.56.1 (59eed8a2a 2021-11-01)

I might add replit has the same issue. Also, If I try checking out an old tag and installing, inotify dependency fails building.

@ghuntley I just tried running through the gitpod link on the README and I was greeted with a gitpod that was using 1.55

I can confirm the same.

Same issue on replit by the way, edition 2021 cannot be found. Rustup is also not accessable.
