Docker無法從package.json文件安裝依賴項

Question

我是docker的新手，並試圖收集我的團隊建立的節點應用程序。 不幸的是，它似乎沒有構建happy.js，這是我的package.json文件中明確說明的依賴項。 這是我的DockerFile的副本：

FROM node:8-alpine

WORKDIR /usr/src/app

ENV UV_THREADPOOL_SIZE 64

COPY cdp-contracts/ ./rpc
COPY cdp-platform/  ./backend

RUN rm -rf backend/node_modules
RUN rm -rf rpc/node_modules

RUN apk add --no-cache --virtual .gyp \
    autoconf \
    automake \
    g++ \
    libpng-dev \
    libtool \
    make \
    nasm \
    python \
    git \
  && npm i -g wait-on concurrently truffle npm@latest \
  # && concurrently 'cd rpc;  npm init -y ; npm install --save-exact openzeppelin-solidity; npm init -y ; npm i npm@latest -g ' \
  # && concurrently 'cd backend; npm init -y ; npm i npm@latest -g ; npm i hapi -g; npm rebuild bcrypt --build-from-source' \
  && concurrently 'cd rpc;  npm init -y ; npm install --save-exact openzeppelin-solidity; npm init -y ; npm i npm@latest -g ' \
  && concurrently 'cd backend; npm init -y ; npm i npm@latest -g ; npm i hapi -g; npm rebuild bcrypt --build-from-source' \
  && apk del .gyp

WORKDIR /usr/src/app/rpc

RUN truffle compile --all

WORKDIR /usr/src/app/backend

RUN mkdir -p build/
RUN ln -sf ../../rpc/build/contracts build/contracts

WORKDIR /usr/src/app/backend

EXPOSE 3001

CMD [ "npm", "run", "middleware" ]

問題出在后端文件夾中。 這是復制到此文件夾的package.json文件的副本：

不幸的是，我一直收到這個錯誤：

我會非常感謝有關這方面的任何指示

您的docker文件運行npm i hapi -g ，因此您在容器上全局安裝hapi，但是在任何時候我都看不到您在workdir上運行npm i 。 所以我猜你的應用程序將無法在node_modules找到任何本地依賴node_modules 。

我建議你嘗試在你的docker文件中添加RUN npm i ，就在WORKDIR /usr/src/app/backend 。
