[email protected]安装vue-i18n报错，peer vue@“^3.0.0“ from [email protected]

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：

npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR!
npm ERR! While resolving: [email protected]
npm ERR! Found: [email protected]
npm ERR! node_modules/vue
npm ERR!   vue@"^2.6.11" from the root project

npm ERR!
npm ERR! Fix the upstream dependency conflict, or retry
npm ERR! this command with --force, or --legacy-peer-deps
npm ERR! to accept an incorrect (and potentially broken) dependency resolution.
npm ERR!

**peer vue@“^3.0.0” from [email protected] ** 这段意思是 版本不匹配

我们可以使用下面命令查看 vue-i18n 所有版本：
npm view vue-i18n versions --json

然后找到合适的版本即可，这里使用的是 5.0.0

npm install vue-i18n@5
