2、问题分析

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

3、解决

上述报错日志中有个关键字眼:this command with --force, or --legacy-peer-deps

使用–force或–legacy-peer-deps可解决这种情况。

何时使用--force--legacy-peer-deps
--force 会无视冲突,并强制获取远端npm库资源,即使本地有资源也会覆盖掉
--legacy-peer-deps:安装时忽略所有peerDependencies,忽视依赖冲突,已有的依赖不会覆盖,。
建议用--legacy-peer-deps 比较保险一点,反正我用了就安装成功了;

执行代码:

npm install --legacy-peer-deps
