-Zbuild-std is broken with the latest nightly. Try using a nightly from a couple of days ago. -Zbuild-std should be fixed within a couple of days.

@bjorn3 There's the same issue on ARM64 device. I tried

cargo generate-lockfile

In the project folder, or

find ~/.rustup/toolchains/nightly-aarch64-unknown-linux-gnu|grep Cargo.toml

will find some toml files on ARM64 host. Still run

cd ~/.rustup/toolchains/nightly-aarch64-unknown-linux-gnu/lib/rustlib/src/rust
cargo generate-lockfile

copy the generated lock file to the expected folder, and works on ARM64 host. It might work on x86_64 hosts. If there aren't any obvious differences between ARM64 and x86 environments, it may work on x86.

If there aren't any obvious differences between ARM64 and x86 environments, it may work on x86.

I tried it on x86_64, it also works. If the host is x86_64, it also has

lib/rustlib/src/rust

in the toolchain folder, copy the generated lockfile into that folder fixed this.

This issue appears to be fixed as of two days ago.
