我想构建自定义 Dockerfile，但我收到以下消息： --> Starting build app ERROR: The Compose file is invalid because: Service app has neither an image nor a build context specified. At least one must be provided.

我不明白为什么叫这个名字app。你可以看到我的 docker-compose.yml 文件：

version: "3"

services:
  webapp-react:
    build:
      context: ./docker/nodejs
      dockerfile: Dockerfile
    image: webapp/react
    container_name: webapp_react
    user: ${UID}:${GID}
    environment:
      - NODE_ENV=build

  webapp-nginx:
    build:
      context: ./docker/nginx
      dockerfile: Dockerfile
    image: webapp/nginx
    container_name: webapp_nginx
    environment:
      - VIRTUAL_HOST=${SITE_URL}
      - VIRTUAL_PORT=8080
      - VIRTUAL_NETWORK=nginx-proxy
      - LETSENCRYPT_HOST=${SITE_URL}
      - LETSENCRYPT_EMAIL=${MAILER_DEFAUT_SENDER_ADDRESS}
    ports:
      - "8181:80"
    volumes:
      - ./app/build:/www-data/ …

我使用jsonplaceholder URL测试fetch API,但我的函数返回"Promise State:Pending",我不明白为什么:

function getUsers(url) {
  return fetch(url)
}

const users = getUsers(`https://jsonplaceholder.typicode.com/users`);

users.then(response => {
  console.log(response.text());
});

我认为问题是因为异步/同步方法？

我想将Vue与webpack一起使用。我已经安装了所有依赖项，但是在编译后发出了警告：

[Vue警告]：您正在使用Vue的仅运行时版本，而模板编译器不可用。可以将模板预编译为渲染函数，也可以使用包含编译器的内部版本。（在发现 ）

我的app.js：

import Vue from 'vue';
import test from './components/cartItem.vue'; // Simple <template> with string

new Vue({
  el: '#js-cart-list'
});

我的package.json：

  "devDependencies": {
    "autoprefixer": "^6.4.1",
    "babel-core": "^6.14.0",
    "babel-loader": "^6.2.5",
    "babel-polyfill": "^6.23.0",

    "cross-env": "^3.2.4",
    "css-loader": "^0.24.0",
    "css-mqpacker": "^5.0.1",
    "eslint": "^3.18.0",
    "eslint-loader": "^1.6.3",
    "exports-loader": "^0.6.3",
    "extract-text-webpack-plugin": "^2.1.0",
    "goog-webfont-dl": "^1.0.1",

    "postcss-loader": "^0.11.1",
    "progress-bar-webpack-plugin": "^1.9.0",
    "sass-loader": "^4.0.1",
    "script-loader": "^0.7.0",
    "slick-carousel": "^1.6.0",
    "style-loader": "^0.13.1",
    "vue-loader": "^11.3.4",
    "vue-template-compiler": "^2.2.6",
    "webpack": "^2.0.0",
    "webpack-notifier": "^1.5.0"
  },
  "dependencies": { …

我用它构建了我的第一个Meteor APP meteor build ../build.

但是,当我启动我的应用程序时node main.js,我错了,因为Meteor搜索信息在我的settings.json中,但是找不到此信息.

你知道设置是否构建？

谢谢大家,

我想在我的 js 文件顶部添加字符串。事实上，已经到了最后：

var file = './public/js/app.bundleES6.js',
    string = '// My string';

    fs.appendFileSync(file, string);

您有想法在第一行添加我的字符​​串吗？

谢谢 ！
