Unable to install toolchain with `rustup install`
For some reason, cargo-msrv now refuses to run in any project on my computer:
$ cargo new foobar
Created binary (application) `foobar` package
$ cd foobar/
$ cargo msrv

Unable to install toolchain with `rustup install 1.56.1-x86_64-unknown-linux-gnu`.
This happens both when installing the latest released version of cargo-msrv, and installing directly from the main branch.
This is particularly weird because when I run the listed command myself, it works without issue:

Thanks for the detailed report! I've tried to reproduce this issue but was unable to.
- What is your current cargo-msrv version?:
cargo msrv --version - Do you have an idea what the last working cargo-msrv version was (or possibly the last time you used it and it worked, date wise)?
- Possibly, cargo-msrv 0.10.0 which was released about a month ago might work for you as an intermediate solution: `cargo install cargo-msrv --version "0.10.0"
Yeah, it's weird, I only have this issue on this computer.
$ cargo msrv --version
cargo-msrv 0.12.0
$ cargo install cargo-msrv --version 0.10.0
$ cargo msrv
# same error as before
However, I did discover that, weirdly enough,
$ cargo-msrv msrv
work just fine! It's just when invoked through Cargo that it fails.
Digging some deeper, I do have CARGO_TARGET_DIR set, and I have $CARGO_TARGET_DIR/bin on my path, so:
$ which -a cargo-msrv
/home/jon/.cargo/bin/cargo-msrv
/home/jon/.cargo-target/release/cargo-msrv
If I execute either of those directly (with the argument msrv) they both work though, so that seems unrelated.
I don't know why executing through cargo would make a difference here. It does mean it'll run through Rustup (whereas it won't when run directly as cargo-msrv), which might change the execution environment (e.g., RUSTUP_HOME and RUSTUP_TOOLCHAIN will be set when invoked through cargo).
It seems that I have the same error on aarch:
$ cargo msrv --version
cargo-msrv 0.15.1
$ cargo msrv
Fetching index
Determining the Minimum Supported Rust Version (MSRV) for toolchain aarch64-apple-darwin
Using check command cargo check
Unable to install toolchain with `rustup install 1.33.0-aarch64-apple-darwin`.
It is due to the fact that the target didn't existed on the channel before: https://github.com/rust-lang/rustup/issues/2413
If I check for this particular version in the static s3 index with:
aws --no-sign-request s3 ls static-rust-lang-org/dist/ |rg '1\.33\.0-aarch64-apple-darwin'
It finds nothing.
I think it is link to the fact that msrv is checking the version without checking if the target was supported.
Here we can see that for edition = 2018 it is minimum 1.31.0. But target aarch64-apple-darwin is supported only for 1.49.0.
I also think that the subcrate rust-releases and msrv are testing for macos through github action runner macos-stable which is a darwin x86_64 or i686 not an aarch64.
If we run the same command but targeting x86_64 we find the expected version.
aws --no-sign-request s3 ls static-rust-lang-org/dist/ |rg '1\.33\.0-x86_64-apple-darwin'
I think a fix would be to pass the target when searching for the latest_stable version.
Hi @Freyskeyd, thanks for the detailed report!
I'm currently working on implementing this for the next release. With a bit of luck, it may also help towards fixing #587.
I have the same problem on Mac.
As a workaround, this worked for me:
docker run --platform=linux/amd64 -t -v "$(pwd)/Cargo.toml":/app/Cargo.toml foresterre/cargo-msrv
Although it actually doesn't work because
