Installing cargo-espflash with cargo fails

[FabienTregan]

Hi. I try installing cargo-espflash but it fails :

~/code/no_std-training$ cargo install cargo-espflash espflash

I think I've tried nightly and stable toolchains. I tried changing the defualt tool chains to those two:

nightly-x86_64-unknown-linux-gnu (default)
stable-x86_64-unknown-linux-gnu

~$ uname -v
#45~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Mon Jul 15 16:40:02 UTC 2
~$ rustup -V
rustup 1.27.1 (54dd3d00f 2024-04-24)
info: This is the version for the rustup toolchain manager, not the rustc compiler.
info: The currently active `rustc` version is `rustc 1.79.0 (129f3b996 2024-06-10)`

After updating the tool chain, (stable to rustc 1.80.1 (3f5fd8dd4 2024-08-06, nightly torustc 1.82.0-nightly (506052d49 2024-08-16)`) the error is still there.

I quickly checked something: on Jun 20 16:41, I installed v3.1.0 on this same computer with no issue, I'm pretty sure the rust install was the same that failed this morning trying to install v3.1.1

[jnnks]

All previous espflash versions (2.x.x) did not work for me either. Always the same error in gix-credentials, across multiple different gix-credentials versions. I assume it has to do with the rust version gix is using, gix-credentials has declared 1.65 in their Cargo.toml.

I ended up installing v3.1.1 using cargo binstall espflash.

Run into the same issue and updating cargo as dependency will fix it. You can look at this commit https://github.com/esp-rs/espflash/pull/666/commits/f00ba45829e25ccc185c3235cba22faaa54791e8 in the open pull request #666 and install from local within the cargo-espflash directory like so -> cargo install --path ./

I tried this but got the same error.

[SergioGasquez]

Use cargo install cargo-espflash --locked to avoid the error

[felix-kolbe]

Use cargo install cargo-espflash --locked to avoid the error

This also solved it for me, trying to install it in WSL (running Ubuntu 24.04.1 LTS). 🎉

[VorpalBlade]

Seems gix broke semver then? Has this been reported to that project so they can yank the bad versions?

[eklipse2k8]

Seeing this when running

cargo install cargo-espflash --locked

warning: package `bytemuck v1.16.0` in Cargo.lock is yanked in registry `crates-io`, consider running without --locked

[isaac-mcfadyen]

Solution above with --locked is working but bytemuck v1.16.0 as well as futures-util v0.3.30 are indeed yanked—if PR #666 fixes it then it might just not be on crates.io yet?

[jessebraham]

We will try to get a new release out soon, our focus has been elsewhere lately. Sorry for any inconvenience, I will update/close this issue when we have published a new version.
