Requirements

  • Is this a bug report? For questions or discussions use https://lemmy.ml/c/lemmy_support
  • Did you check to see if this issue already exists?
  • Is this only a single bug? Do not put multiple bugs in one issue.
  • Do you agree to follow the rules in our Code of Conduct?
  • Is this a backend issue? Use the lemmy-ui repo for UI / frontend issues.

Summary

I've been following the advice on Local Development to install lemmy as a local instance.
When trying to run cargo check it hits an error.
The Rust issue log for lazy_cell recommends installing rustup but it requires rust to be uninstalled first - so I haven't done that yet.
###Short version
cargo check

Checking lemmy_utils v0.19.6-beta.7 (/home/USER/lemmy/crates/utils)
error[E0658]: use of unstable library feature 'lazy_cell'

Full error is below.

Steps to Reproduce

  1. git clone https://github.com/LemmyNet/lemmy.git --recursive
  2. git clone https://github.com/LemmyNet/lemmy-ui.git --recursive
  3. cd lemmy
  4. cargo check

Sounds like your Rust version is too old, try installing it from https://rustup.rs/
