Cannot install from sourcedist

Bắt đầu bằng cách tái hiện lệnh pip install ipykernel --no-binary :all: và kiểm tra lỗi phân lập bản dựng trong khi cài đặt flit. Issue được hoàn tất khi bản phân phối mã nguồn của ipykernel cài đặt thành công với tính năng phân lập bản dựng được bật.

This appears to fail with flit (even if flit is installed)

Disabling build isolation with --no-build-isolation appears to be fixing it if flit is already installed in the environment.
