问题描述

我已经从git中克隆了一个angular 4项目.

I have cloned an angular 4 project from git.

当我转到项目的根文件夹并执行ng时.

When I go to the root folder of the project and did ng serve.

我遇到以下错误. node_modules显示为空，您可能需要运行npm install

I am getting following error. node_modules appears empty, you may need to run npm install

如何解决以上错误.

推荐答案

从项目的根目录运行npm install.如果您使用的是Mac，则可能需要运行sudo npm install，以防某些软件包安装需要提升的权限.如果它包含子模块，请在下面留下评论，我将更新此答案以包括如何处理这些问题.除非您按了它，否则不要将这个答案与此混淆.

Run npm install from the root of the project. If you're on a mac then you may want to run sudo npm install in case some of the package installations require elevated permissions. If it has submodules then leave a comment below and I'll update this answer to include how to deal with those. No use in confusing this answer with that unless you hit it.
