npm安装vuex3报错

Question

问题遇到的现象和发生背景

用npm安装vuex3。
安装命令：

npm i --save vuex@3

输入后出现以下错误：

npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR! 
npm ERR! While resolving: undefined@undefined
npm ERR! Found: vue@3.2.40

好像说的是我电脑同时有vue3和vue2，不能把vuex3弄到我这个vue2的项目上。这个如何解决？

Answer 1

npm list vue//为3版本，所以要卸载
npm uninstall vue
npm install vue@2
npm i vuex@3 --save
