npm run build无法打包 ERR! missing script: build

vue项目打包出现错误

PS D:\****\*****> npm run build
npm ERR! missing script: build

在package.json中 scripts下有 “build:prod”: "vue-cli-service build"

"scripts": {
    "dev": "vue-cli-service serve",
    "build:prod": "vue-cli-service build",
    "build:stage": "vue-cli-service build --mode staging",
    "preview": "node build/index.js --preview",
    "lint": "eslint --ext .js,.vue src",
    "test:unit": "jest --clearCache && vue-cli-service test:unit",
    "test:ci": "npm run lint && npm run test:unit",
    "svgo": "svgo -f src/icons/svg --config=src/icons/svgo.yml",
    "new": "plop"
  },

SO 不能用 npm run build来打包
应该用

 npm run build:prod --report
