nodejs npm

使用npm安装依赖时遇到一点儿麻烦，输入命令 npm install 收到以下错误：

D:\Demo\vkt.demo.ant>npm install

由以上信息可以看到有关于react和ant-design还有ant-design-pro之间的一场冲突。这个也正是我在安装框架ant-design-pro时遇到的。
解决办法：

 npm i --legacy-peer-deps

安装一些包，可能会花一点儿时来下载根据网络情况来定。最终效果如下：

001

再次输入npm install

D:\Demo\vkt.demo.ant>npm install
npm WARN deprecated fsevents@1.2.13: fsevents 1 will break on node v14+ and could be using insecure binaries. Upgrade to fsevents 2.

> ant-design-pro@4.5.0 postinstall
> umi g tmp

庭院深深深几许？杨柳堆烟，帘幕无重数。
玉勒雕鞍游冶处，楼高不见章台路。
雨横风狂三月暮。门掩黄昏，无计留春住。
泪眼问花花不语，乱红飞过秋千去。
