错误错误：找不到模块'@ xtuc / long'

Question

我正在学习vueJs，我已经使用CLI安装了我的项目，并且已经成功安装了项目，当我需要使用npm run serve命令通过终端运行我的项目时，问题就来了，以下是在运行vueJs之后发生的错误命令

$ npm运行发球

  https://localhost:8080

如果您没有在项目中进行任何更改，只需尝试安装并运行第一个vue.js应用程序，然后按照本指南Creating a Project CLI进行操作，一切都会好起来的。 确保使用最新版本的node＆npm。

如果您要修复此项目，请尝试删除node_modules和package-lock.json文件，然后运行npm install
