我正在尝试bringup.qemu-arm64在我的 Nvidia Jetson Nano 板上构建 Zircon 内核，但我得到：
lz@jetson:~/fuchsia$ fx --enable=legacy_set set bringup.qemu-arm64
Generating compile_commands took 1440ms
Generating rust-project.json took 975ms
Done. Made 145000 targets from 5124 files in 130268ms
lz@jetson:~/fuchsia$ fx build
ninja: Entering directory `/home/lz/fuchsia/out/default'
ninja: error: '../../prebuilt/third_party/rust_tools/linux-arm64/.versions/rust_tools.cipd_version', needed by 'fidling/gen/sdk/fidl/fuchsia.io/fuchsia.io/fidl_fuchsia_io.rs', missing and no known rule to make it
Hint: run `fx build` with the option `--log LOGFILE` to generate a debug log if you are reporting a bug.
如何使丢失的回购出现？
