error: could not compile `sp-panic-handler` (lib) due to 4 previous errors
warning: build failed, waiting for other jobs to finish...
error: failed to compile `try-runtime-cli v0.8.0 (https://github.com/paritytech/try-runtime-cli?tag=v0.8.0#95cff053)`, intermediate artifacts can be found at `/var/folders/c0/wqgh59fj3j7b6hjphk6mpfgw0000gn/T/cargo-installAnHz5r`.
To reuse those artifacts with a future compilation, set the environment variable `CARGO_TARGET_DIR` to that path.

Have to use cargo +nightly ...

Tái hiện lỗi bằng cách build try-runtime-cli với toolchain stable và so sánh với bản build nightly. Bắt đầu từ substrate/primitives/panic-handler/src/lib.rs trong dependency đã được checkout, sau đó xác định thay đổi cần thiết trong project để bản build với toolchain stable hoàn tất mà không có các lỗi E0658 lazy_cell.
