Question

我有一个dockerized角度应用程序，使用“docker-compose up”时无法启动。我将应用程序停靠，因为我想将它分发给同学等。

图像的构建工作得很好。

请在帖子末尾找到错误消息。

这是我对角度部分的Dockerfile：

FROM node:9.4.0

RUN mkdir -p /usr/src/app

WORKDIR /usr/src/app

COPY package.json /usr/src/app

RUN npm install --save

COPY . /usr/src/app

EXPOSE 4200

CMD ["npm", "start"]

这是我的Docker-compose文件的角度相关部分：

angular:
    build: ../angular
    container_name: ng
    ports:
      - "4200:4200"
    volumes:
      - ../angular:/usr/src/app

我在启动时遇到这种错误。

angular@0.0.0 start /usr/src/app

ng serve -H 0.0.0.0

sh: 1: ng: not found

npm ERR! file sh

npm ERR! code ELIFECYCLE

npm ERR! errno ENOENT

npm ERR! syscall spawn

npm ERR! angular@0.0.0 start: `ng serve -H 0.0.0.0`

npm ERR! spawn ENOENT

npm ERR!

npm ERR! Failed at the angular@0.0.0 start script.

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm WARN Local package.json exists, but node_modules missing, did you mean to install?

如果您对dockerfiles或compose文件中的更改有任何想法，请告诉我。非常感谢你提前。

试试这个......

    if (MyApplication.isAppOpen() &&
                DashboardActivity::class.simpleName?
.equals(MyApplication.displayActivity) ?: false) {
// you can eliminate the last condition if you wish

            playAlertTone(context) // or whatever
        } else {
           // your notification building code
        }

Answer 2

我最终不得不删除容器的卷

docker-compose rm -v angular

这是因为我已经挂载了 node_modules/ 以避免覆盖这些，因为我们通过容器挂载 js 源<->主机挂载以进行热重载。

Angular docker-组成不起作用
