Question

我尝试在docker-compose环境中添加angular6应用。我在本地创建了项目并且它可以正常工作，但在docker-compose build和docker-compose up之后，它会发送下一个错误：

angular6@0.0.0 start /usr/src/app
> ng serve --host 0.0.0.0 --disable-host-check -p 3000

Could not find module "@angular-devkit/build-angular" from "/usr/src/app".

这是我的Angular Dockerfile：

# Create image based on the official Node 8.10.0 image from dockerhub
FROM node:8.10.0
# Create a directory where our app will be placed
RUN mkdir -p /usr/src/app

# Change directory so that our commands run inside this new directory
WORKDIR /usr/src/app

# Copy dependency definitions
COPY ./quickstart /usr/src/app

# Install dependecies
RUN rm -rf node_modules/

RUN npm i --save

RUN npm i npm@latest -g
RUN npm install -g @angular/cli

# Expose the port the app runs in
EXPOSE 4200

# Serve the app
CMD ["npm", "start"]

模块@angular-devkit/build-angular已正确安装并包含在package.json

中

Answer 1

您的docker文件中有错误您做了一个 WORKDIR ，并将其设置为 / usr / src / app

这意味着上下文将切换到该文件。

因此，当您执行this.service.get_items().subscribe((res) => { // request data will be here in the res });时，应为COPY ./quickstart /usr/src/app

码头工人文件说

COPY ./quickstart .

Answer 2

我发现了问题。

我在docker-compose.yml中删除了一行。

angular-ayaresa:
    build:
      context: build/angular
    ports:
          - "4200:4200"
    volumes:
      - ../source/angular:/usr/src/app/
      - /usr/src/app/node_modules/ // <-- this line
    container_name: angular-ayaresa
    networks:
      - ayaresa-network

此行允许容器忽略卷中的文件夹。

问题是node_modules包含在卷中，Angular从本地"@angular-devkit/build-angular"而不是容器node_modules中搜索模块node_modules。

我只添加了忽略node_modules，问题就解决了。

Angular 6.0.3在docker中不起作用，因为它无法找到module @ angular-devkit / build-angular
