🍖 前言

npm i --legacy-peer-deps，解决依赖冲突问题

🎶 一、问题描述

node执行安装指令时出现报错，如下：

npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR!

✨二、代码展示

代码如下：

npm i --legacy-peer-deps

🏀三、运行结果

控制台输出展示:

🏆四、知识点提示

知识点1：

• –legacy-peer-deps 标志允许在 npm 7 中使用旧版的 peer dependency 解析算法，这相当于回退到 npm 6 之前的解析方式
• 在从 npm 6 迁移到 npm 7 时，一些包可能还未更新以适应新的 peer dependencies 规则，此时可以使用 --legacy-peer-deps 保证依赖安装顺利进行
