How to address docker compose not found

Problem Statement

如果之前有安裝過docker-compose，而且主要的command是中間有個dash，那是舊的版本，可以參考“docker compose”和”docker-compose”之間的區別，但更新的版其實是把dash拿掉，因為要把compose合併到docker的command，這樣的話就需要安裝plugin

Solution

以結論來說就是只要安裝docker-compose-plugin，這個套件，但是我自己遇到以下問題，所以最後一部分是GPT給我的答案，也成功解決問題
