dockerチュートリアルでnpmエラー

Posted at

##Dockerの公式ドキュメント
Docker document Quickstart part2でエラーが発生
$ docker build --tag bulletinboard:1.0 .の部分で

##やったこと1
Node.jsとnpmを直接インストール
インストール方法
インストールあと以下のサイトで設定
Node.jsのPath(パス)を確認する方法【初心者向け】
あとコントロールパネル>システム>アドバンスドシステム設定(左下)>環境変数>システム変数のpathを編集してC:\Program Files\nodejs\を追加(自動でできてるかも)

##やったこと2
bulletin-board-appファイル内のpackage-lock.jsonファイルを削除して
$ docker build --tag bulletinboard:1.0 .を実行

まだエラー出ていたので、dockerfileの5行目にRUN npm cache verify



FROM node:current-slim

WORKDIR /usr/src/app
COPY package.json .
RUN npm cache verify
RUN npm install 

EXPOSE 8080
CMD [ "npm", "start" ]

COPY . .

##なんとなくうまくいった?

$ docker build --tag bulletinboard:1.0 .

##結論
もっとNode.jsやらの知識を身に着けてからの方がいい
