`PyCall` build error owing to `JSONDecodeError`

Bắt đầu bằng cách tái hiện Pkg.build("PyCall") và kiểm tra deps/build.jl xung quanh lời gọi Conda.add, đồng thời xem runner xử lý tiến trình của Conda.jl trong src/Conda.jl. Truy vết conda JSONDecodeError và xác định liệu quá trình build có thể cài đặt numpy thành công hay không; hoàn tất nghĩa là bản build PyCall được báo cáo hoàn thành trên thiết lập macOS arm64 đã nêu.

was working a few days ago, but after an up, build PyCall fails, with the following build log.

Collecting package metadata (current_repodata.json): ...working... failed
