结果报错npm ERR! missing script: build，后来发现package.json中scripts参数为
"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" },
所以正确的命令应该为
npm run build:prod --report
