Can't -Zbuild-std in rustc 1.82.0-nightly (8b3870784 2024-08-07).

[Wyvern]

Update to latest rustc 1.82.0-nightly (8b3870784 2024-08-07), get error when using -Zbuild-std:

error: "/Users/runner/.rustup/toolchains/nightly-aarch64-apple-darwin/lib/rustlib/src/rust/Cargo.lock" does not exist, unable to build with the standard library, try:
        rustup component add rust-src --toolchain nightly-aarch64-apple-darwin

but rust-src component already installed.

There's no need to comment any more targets, or that you are also running into this. It applies to all targets, and we already know this is happening.

This semes to be a Cargo bug (or something need to be adjust accordingly)

• Before nightly-aarch64-apple-darwin/lib/rustlib/src/rust/Cargo.lock
• After nightly-aarch64-apple-darwin/lib/rustlib/src/rust/library/Cargo.lock

A PR is up: rust-lang/cargo#14370

When will the cargo change be picked up by nightly?

$ rustc +nightly --version
rustc 1.82.0-nightly (3e9bd8b56 2024-08-08)
$ cargo +nightly --version
cargo 1.82.0-nightly (94977cb1f 2024-08-06)

Edit: it's in #128827, so presumably tomorrow

[weihanglo]

Yes, tomorrow. We missed yesterday's window for just a few minutes 😞.
