Question

我正在尝试将我的应用容器化以将其部署到GCP。在进行任何触发器设置之前，我一直在进行一些本地测试，由于某种原因，尽管在package.json中列出了rxjs（也许还有其他）都没有安装。

在我的Dockerfile中，它在构建步骤中出错，因为它找不到rxjs模块（RUN ls node_modules显示它甚至在安装后也不存在）。我已经明确尝试添加RUN npm install rxjs，但是那还是行不通的。当我这样做时，我遇到了很多其他错误，因为它们找不到npm正在暂存的模块。这种情况在我的本地计算机和我试图构建/部署的Cloud Run实例上都发生。

在任何人提到它之前，我都尝试过删除package-lock.json并进行全新安装-结果完全相同。当我实际上直接从命令行构建它时，一切都可以正常工作。似乎更像是Docker容器的问题。

Dockerfile

FROM node:12.18-alpine AS dev

WORKDIR /usr/src/app

COPY package*.json ./

RUN npm install --only=dev

COPY . .

RUN npm run build:prod

FROM node:12.18-alpine AS prod

ARG NODE_ENV=production
ENV NODE_ENV=${NODE_ENV}

WORKDIR /usr/src/app

COPY package*.json ./

RUN npm install --only=prod

COPY . .

COPY --from=dev /usr/src/app/dist ./dist

第4/15步：运行npm install --only = dev --->使用缓存

只要您在构建时遇到一些问题，我建议您在不使用缓存的情况下进行构建。只需添加--no-cache，以确保确实调用了npm install。

docker build --no-cache -t mybuild:v1 .

在Dockerfile中没有从package.json安装依赖项（RxJS）吗？
