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 clone_project 目录运行 npm run serve 时出现以下错误：

> design@0.1.0 serve /Users/path_to_clone_project/clone_project
> vue-cli-service serve

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

Error: Cannot find module '../package.json'

原始项目是使用 Vue CLI 工具创建的。我不明白这个错误，因为 package.jsonfile 已按预期与项目的其余部分一起复制。

删除您的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 中定义的所有包。

然后运行npm run serve
