项目场景:
在vue中安装vue-router
问题描述:
提示:在安装过程中报错,缺少依赖:
PS D:\WebDeplpyer\workspace\Vue_Basic\vue_test> npm i vue-router
npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR!
npm ERR! While resolving: vue_test@0.1.0
npm ERR! Found: vue@2.6.14
npm ERR! node_modules/vue

原因分析:
查阅资料,大部分都说是npm版本问题,新版本对下载要求比较严格。
解决方案:
根据错误提示,在命令行中加入–legacy-peer-deps,由于vue与vue-router版本兼容的问题,需要在安装语句后加入需要下载vue-router版本,不然会下载最新的vue-router版本。
npm install --legacy-peer-deps vue-router@4.0.13
也有可能因为是你要下载的router版本过高,如果下载版本过高,在启动项目时会报错,可以下载低版本的vue-router
npm install vue-router@3.1.3 --save-dev
在package.json文件中查看是否下载成功
