Vue打包npm run build时报错：npm ERR! missing script: build的问题处理

使用element-vue打包项目npm run build的时报错：npm ERR! missing script: build

在项目根目录下的package.json中发现问题所在：

 "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"
  },

所以需要修改一下打包的命令，正确的命令为：

npm run build:prod --report
