###解決策はこちら
####store/index.jsを作成

####FROM node:16-alpineにDockerfileを変更

nodeとyarnバージョン

$ node -v
v14.18.1

$ yarn -v
1.22.15

###発生したエラー
####store/index.jsがない

Docker起動時

$ docker compose up --build

...(略)
nuxt_1  | yarn run v1.22.15

storeディレクトリ配下にindex.jsという名前のファイルを作る必要があるという意味。詳しくはわかっていませんが、保管用のディレクトリなのかしら？？

とりあえず起動には必要みたいなので、作成し再度実行します。（中身は空でOK）

####ハッシュ関数のエラー！？

いろいろ調べたけど、結局Node.jsのバージョンによるエラーっぽいです。
17にはバグがあるから16のバージョンにする必要があるようです。

Dockerfileを編集して、nodeのバージョンを16に指定します。

###Dockerfileを編集してnode16をインストールするように変更

dockerfile

#ここで16を指定。もともとnode:alpineでした（最新版を持ってくる？）
FROM node:16-alpine

EXPOSE 3000
ENV HOST 0.0.0.0

RUN apk update && \
  apk add git vim && \
  yarn global add @vue/cli nuxt create-nuxt-app

これで再度起動

$ docker compose up --build
...

問題なく終了しているので、これでlocalhost:3000でアクセスすることで画面が起動できるようになった！！ばんざーい＼(^o^)／
