error: failed to compile `just v1.34.0`, intermediate artifacts can be found at `/tmp/cargo-installhep2UA`

Caused by:
  failed to select a version for `env_logger`.
      ... required by package `just v1.34.0`
  versions that meet the requirements `^0.11.0` are: 0.11.5, 0.11.4, 0.11.3, 0.11.2, 0.11.1, 0.11.0

  the package `just` depends on `env_logger`, with features: `anstream` but `env_logger` does not have these features.
   It has an optional dependency with that name, but that dependency uses the "dep:" syntax in the features table, so it does not have an implicit feature with that name.

I'm not able to reproduce this. What version of Rust are you using?

[cxp-13]

It's fail on cargo 1.70.0 (ec8a8a0ca 2023-04-25), but success on cargo 1.80.0 (376290515 2024-07-16)

This has happened before -
#1898
#1980

In the case of this issue, just does declare it's supposed to work with Rust/Cargo 1.70 -

just/Cargo.toml

Line 15 in f9c2479

rust-version = "1.70"

But just uses Cargo.toml [lints], which requires Rust/Cargo 1.74, and https://just.systems/man/en/chapter_84.html says MSRV is actually current stable Rust, i.e. currently 1.80.0.

I can reproduce this issue with Rust 1.70.0, but not with Rust 1.74.1. Should the MSRV declared in Cargo.toml be updated?

Although, does just need to depend on env_logger and log? AFAICT it's only used in two places:

just/src/config.rs

Line 754 in f9c2479

warn!("Failed to set CTRL-C handler: {error}");

just/src/run.rs

Line 19 in f9c2479

info!("Parsing command line arguments…");

Good point! I removed logging in #2305.

I also bumped the MSRV to 1.74 in #2306, and confirmed that it builds with 1.74, so I think this can be closed.
