问题描述

当我尝试运行简单的npx create-react-app时，收到以下错误：

D:>npx create-react-app abc
npx: installed 67 in 4.255s

Creating a new React app in D:abc.

Installing packages. This might take a couple of minutes.
Installing react, react-dom, and react-scripts with cra-template...


Aborting installation.

发了一个问题

推荐答案

似乎写权限有问题。

尝试使用提升的权限从cmd运行npx create-react-app myapp，即以管理员身份运行cmd，然后尝试创建/搭建你的应用。
