原因

在新版本的npm中，默认情况下，npm install遇到冲突的peerDependencies时将失败。

解决

使用–force或–legacy-peer-deps可解决这种情况。

-force 会无视冲突，并强制获取远端npm库资源，当有资源冲突时覆盖掉原先的版本。

-legacy-peer-deps：安装时忽略所有peerDependencies，忽视依赖冲突，采用npm版本4到版本6的样式去安装依赖，已有的依赖不会覆盖。
建议用--legacy-peer-deps 比较保险一点
npm install --registry=https://registry.npmmirror.com --legacy-peer-deps
