npmmissingscript：dev报错解决方法。

npm missing script&＃xff1a;dev报错解决方法。

打开package.json文件&＃xff1a;
修改"scripts"{}中的属性内容为&＃xff1a;

"scripts": {"serve": "vue-cli-service serve","build": "vue-cli-service build","lint": "vue-cli-service lint","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","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&＃61;src/icons/svgo.yml","new": "plop"}


再次npm run dev 成功解决
