rust-toolchain.toml causes 'cargo' component, is not applicable

[cataggar]

rust-toolchain.toml from #1006 is causing an error when I try to run cargo:

PS C:\Users\cataggar\io\azure-sdk-for-rust> cargo check -p identity --examples
error: the 'cargo.exe' binary, normally provided by the 'cargo' component, is not applicable to the '1.63.0-x86_64-pc-windows-msvc' toolchain

PS C:\Users\cataggar\io\azure-sdk-for-rust> rustc --version
rustc 1.63.0 (4b91a6ea7 2022-08-08)

Interesting, do you happen to not use rustup? That is the only thing I can think of that might cause issues, because I am pretty sure it expects to use rustup to manage everything. In fact this is explicitly a rustup feature.

I can confirm that on my Windows machine (where I do use rustup) that this works as expected. If it is the case that we require users to use rustup we should definitely document that. However, I'm not really convinced that the tradeoff is worth it. We upgrade to new toolchains very quickly, and we're really only saving users on old toolchains the hassle of being reminded to update their toolchain when CI fails.

I'm using rustup. I updated to 1.63.0 using rustup.

PS C:\Users\cataggar\io\azure-sdk-for-rust> cmd /c where rustup
C:\Users\cataggar\.cargo\bin\rustup.exe
PS C:\Users\cataggar\io\azure-sdk-for-rust> rustup --version
rustup 1.25.1 (bb60b1e89 2022-07-12)
info: This is the version for the rustup toolchain manager, not the rustc compiler.
info: The currently active `rustc` version is `rustc 1.63.0 (4b91a6ea7 2022-08-08)`

[cataggar]

@rylev, do you have rustup 1.25.1 on your Windows machine? rustup self update

[rylev]

I do indeed:

> rustup --version
rustup 1.25.1 (bb60b1e89 2022-07-12)

Found one issue online that seems to mirror what you're seeing here. The solution that seemed to work was to uninstall and reinstall the toolchain. That might be the easiest. The other option is building rustup locally and debugging it...

[cataggar]

rust-lang/rustup#2704 has a similar error message, but was marked as a duplicate of rust-lang/rustup#988 . I removed all my toolchains with rustup toolchain remove and readded a couple. It is working now.

Here is my toolchain list before and after:

PS C:\Users\cataggar\io\azure-sdk-for-rust> rustup toolchain list
stable-x86_64-pc-windows-msvc (default)
nightly-x86_64-pc-windows-msvc
ms-1.58
1.63.0-x86_64-pc-windows-msvc (override)

PS C:\Users\cataggar\io\azure-sdk-for-rust> rustup toolchain list
stable-x86_64-pc-windows-msvc (default)
1.63.0-x86_64-pc-windows-msvc (override)

[cataggar]

I had to reinstall the toolchains again to get this to work for me with 1.64. I got the same error as before.

@cataggar I think I am running into the same issue you have here. I am a bit new to rust and trying to learn how to use this SDK.

PS D:\RustProjects\azure-sdk-for-rust> rustup toolchain list
stable-x86_64-pc-windows-msvc (default)
1.64.0-x86_64-pc-windows-msvc (override)

PS D:\RustProjects\azure-sdk-for-rust> rustup --version
rustup 1.25.1 (bb60b1e89 2022-07-12)
info: This is the version for the rustup toolchain manager, not the rustc compiler.
info: The currently active rustc version is (rustc does not exist)

I think I have the same toolchain list as you but still cannot get this project to build

PS D:\RustProjects\azure-sdk-for-rust> cargo build
error: process didn't exit successfully: rustc -vV (exit code: 1)
--- stderr
error: the 'rustc.exe' binary, normally provided by the 'rustc' component, is not applicable to the '1.64.0-x86_64-pc-windows-msvc' toolchain

I am wondering what I am doing wrong. Any assistance would be greatly appreciated.

[rylev]

Can you run the following and try again?

rustup toolchain uninstall 1.64.0-x86_64-pc-windows-msvc
rustup toolchain install 1.64.0-x86_64-pc-windows-msvc

[testingapisname]

@rylev that got me working to get a build going.

Now just to figure out how to use the SDK :) Thanks for the assist!

I think this happened to me just now (Intel Mac running macOS Ventura 13.4.1) because I had a network hiccup while installing the toolchain:

info: downloading component 'rust-docs'
info: retrying download for 'https://static.rust-lang.org/dist/2023-06-01/rust-docs-1.70.0-x86_64-apple-darwin.tar.xz'
warning: bad checksum for cached download
error: component download failed for rust-docs-x86_64-apple-darwin: could not rename downloaded file from '/Users/tkeating/.rustup/downloads/9c30ce1f6308a379e677021e00e18f185cc708b4edbddacd193f1fb3e0979c27.partial' to '/Users/tkeating/.rustup/downloads/9c30ce1f6308a379e677021e00e18f185cc708b4edbddacd193f1fb3e0979c27'

Nuking the toolchain and letting rustup reinstall it seems to have fixed the problem.
