在Windows 7上恢复系统后，vue cli-> npm run dev停止工作

Question

大家。 我无法通过npm run dev命令运行任何vue js项目，但我尝试通过多种方法进行修复：

• 重新安装NodeJ，
• 更新npm，
• 通过cli重新安装新的vue项目-根据vue官方文档，
• 删除％Appdata％npm文件。

即使在新的Vue项目npm run dev也不起作用。 谁能帮我？

这是我的日志：

Answer 1

我没有弄清楚如何修复npm run dev ，但是我尝试了yarn。

$ npm install -g yarn

$ vue init webpack

-> Should we run npm install for you after the project has been created? (recommended) `yarn`

$ yarn run dev

这解决了我的问题，我能够通过yarn run dev运行我的项目。
