Bắt đầu bằng cách tái hiện quá trình cài đặt Quickstart với Python 3.7 và kiểm tra xem timeout từ files.pythonhosted.org có xảy ra lần nữa hay không. Được xem là hoàn tất khi xác định được vấn đề cài đặt riêng của dự án hoặc ghi lại rằng lỗi là do timeout bên ngoài của pip hoặc mạng, kèm theo một cách khắc phục được hỗ trợ.
