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

一、报错

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

二、原因

解析依赖树失败，是因为npm@7更加严格。通常，最简单的解决方法是将--legacy-peer-deps标志传递给npm(e.g.，npm i --legacy-peer-deps），或者使用npm@6。

三、解决方法

npx -p npm@6 npm i @craco/craco  --legacy-peer-deps

这样我的@craco/craco依赖就可以成功注入了
