在vue2环境下，默认安装 npm install vue-i18n 的版本是 [email protected]，所以报错信息如下：
PS D:\myFile\dev\YSJ-dev\cbj-mall-manage> npm i vue-i18n -save npm ERR! code ERESOLVE npm ERR! ERESOLVE unable to resolve dependency tree npm ERR! npm ERR! While resolving: [email protected] npm ERR!

npm ERR! peer vue@"^3.0.0" from [email protected] （意思是版本不匹配）
npm view vue-i18n versions --json 命令查看所有的版本
选择安装合适的版本即可
后面我 使用的是5.0.0 npm install vue-i18n@5
