問題描述

你的系統顯示運行於 WSL2（Windows Subsystem for Linux 2）環境中。在 WSL2 中，systemd 默認未啟用，這也是為什麼 sudo systemctl 無法正常運行的原因。

在 WSL2 中，必須手動啟動 Docker Daemon，因為它不會像在完整的 Linux 系統中那樣自動運行。

執行以下命令以手動啟動 Docker Daemon：
$ sudo dockerd

每次使用 Docker 時，你需要手動啟動 Docker Daemon (dockerd) 並在另一個終端窗口中執行 Docker 命令。這是因為 WSL 本身並沒有像完整的 Linux 發行版一樣，預設啟動 dockerd 作為系統服務。

after $ sudo dockerd,
$ sudo docker run -it –rm -p 8888:8888 sysprog21/chisel-bootcamp
in another terminal

Chisel

Basic types

All signed numbers are represented using 2's complement in Chisel.

By default, Chisel will determine the width of your literal to be the minimum necessary. Alternatively, you can provide a width value as a second argument if needed.
