angular - Docker Angular运行脚本问题

Question

我的 Dockerfile对于 Angular 应用程序

FROM node:10.15.3-alpine as builder

RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app

RUN apk add git
COPY package*.json /usr/src/app/
RUN npm i

COPY . /usr/src/app

RUN npm run-script build

它在最后一步退出并出现以下错误:

npm ERR! missing script: build

npm ERR! A complete log of this run can be found in:
npm ERR!     /root/.npm/_logs/2019-05-24T09_05_54_385Z-debug.log

在这种情况下是否缺少运行脚本或构建选项？以及如何解决或有什么替代方法？

脚本部分的 package.json

"scripts": {
    "ng": "ng",
    "edu-start": "ng serve --project edu-app",
    "edu-start-with-api": "ng serve --project edu-app --configuration local_api",
    "edu-start-with-nodejs": "ng serve --project edu-app --configuration local_nodejs",
    "edu-build-dev": "node --max_old_space_size=2048 ./node_modules/@angular/cli/bin/ng build --project edu-app --configuration hmr",
    "edu-build-prod": "node --max_old_space_size=2048 ./node_modules/@angular/cli/bin/ng build --project edu-app --configuration production --prod",
    "air-pilot-start": "ng serve --project air-pilot-app",
    "air-pilot-build-dev": "node --max_old_space_size=2048 ./node_modules/@angular/cli/bin/ng build --project air-pilot-app --configuration hmr",
    "air-pilot-build-prod": "node --max_old_space_size=2048 ./node_modules/@angular/cli/bin/ng build --project air-pilot-app --configuration production --prod",
    "test": "ng test",
    "lint": "ng lint",
    "e2e": "ng e2e",
    "bundle-report": "webpack-bundle-analyzer dist/stats.json"
  },

我也尝试过这个，但都没有奏效，提示 ng Not Found

RUN ng build --prod --project edu-app

Answer 1

没有build脚本部分的命令，这就是你得到 missing script: build 的原因.

所以添加到 package.json :

    "scripts": {
       "build": "ng build --prod --project edu-app"
      }

至于这个和ng未找到您报告的问题，这是正常的 @angular/cli尚未在容器中全局安装。你在这里有两个选择，

要么全局安装npm -i -g @angular/cli

或通过node_modules中的路径直接访问它

我推荐第一个解决方案，因为它更清晰。

因此，在我在上面告诉您的脚本部分进行更改后，您的 Dockerfile应该:

FROM node:10.15.3-alpine as builder

RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app

RUN apk add git
COPY package*.json /usr/src/app/
RUN npm i

COPY . /usr/src/app

RUN npm -i -g @angular/cli && npm run-script build
