我是 Docker 新手，正在尝试将我的团队构建的 Node 应用程序容器化。不幸的是，它似乎没有构建 happy.js，这是我的 package.json 文件中明确说明的依赖项。 这是我的 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 \

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" ]
问题出在后端文件夹中。 以下是复制到此文件夹的 package.json 文件的副本:

我将非常感谢对此的任何指示
最佳答案
您的 docker 文件运行 npm i hapi -g，因此您在容器上全局安装 hapi，但我从未看到您在工作目录上运行 npm i。所以我猜你的应用程序将无法在 node_modules 中找到任何本地依赖项。
我建议您尝试在 docker 文件中的 WORKDIR/usr/src/app/backend 行之后添加 RUN npm i。
关于node.js - Docker 无法从 package.json 文件安装依赖项，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/53608296/
