javascript - React 安装相关问题,请教一下大家:

问题描述

问 题

我从如下地址上面以 zip 形式下载了一份 v15.3.1 的react代码。

https://github.com/facebook/react/tree/v15.3.1

解压缩后,打开目录,进入目录中,使用

npm install 

来安装包所依赖的控件,但是他报了如下错误:

> react-build@15.3.1 postinstall C:\Users\chenglin.song\Desktop\UAT\个人学习\React\react-15.3.1
> node node_modules/fbjs-scripts/node/check-dev-engines.js package.json

截图如下:

我简单看了一下错误描述,然后查看了一下自己的npm 版本:

无法理解到底为什么错了，还是说就不可以这么安装?

解决方案

报错信息：

Current npm version is not supported for development, expected "4.1.1" to satisfy "2.x || 3.x".

npm版本不符合，把你的npm降到3试试。
