我如何复制VueJS项目？

Question

[当尝试使用cp -r project clone_project简单地复制整个VueJS项目时，从npm run serve目录运行clone_project时出现以下错误：

> vue-cli-service serve

internal/modules/cjs/loader.js:613
    throw err;
    ^

原始项目是使用Vue CLI工具创建的。我不理解该错误，因为package.json文件已按预期与项目的其余部分一起复制。

删除node_modules文件夹并运行npm install。

npm install将创建node_modules文件夹并安装package.json中定义的所有软件包。

然后运行npm run serve
