问题是您的
vue和vue-router版本不兼容。vue@2需要vue-router@3vue@3需要vue-router@4错误消息表明您有
vue@2.6.14,并且您正在尝试安装vue-router@4.0.15。请注意,npm install -S vue-router(不带版本说明符)默认为最新版本,即当前4.0.15。不要使用错误消息中建议的
--force或--legacy-peer-depsnpm 标志,因为这只会安装不兼容的软件包将导致运行时错误。解决方案
快速解决方法是安装
vue-router@3:或者您可以升级到 Vue 3,这需要卸载
vue-template-compiler(Vue 2 的模板编译器)并安装@vue/compiler-sfc( Vue 3 的模板编译器):
