尝试运行命令 npx create react app 时创建 React App 出错：spawn UNKNOWN

Question

当我尝试运行一个简单的程序时，npx create-react-app我收到此错误：

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.
Unexpected error. Please report it as a bug:

我使用的是 Windows 10 版本 20H2 和节点 v14.15.4。

我也在官方create-react-appgithub上提出了一个问题here

Answer 1

我猜这个错误是由于不支持的全局安装而发生的create-react-app。

这个问题有一个小问题，那就是create-react-app不再支持全局安装。所以首先，运行这个命令

npm uninstall -g create-react-app

create-react-app然后按照这样的方式安装

npm install create-react-app

然后创建你的反应应用程序

npx create-react-app my-app
