问题产生的原因和如何解决，其实npm已经列在了最后：

npm ERR! this command with --force, or --legacy-peer-deps

问题原因是依赖冲突导致不能下载依赖包（dependency conflict），

因为npm版本升级（version>7），

npmV7之前的版本遇到依赖冲突会忽视依赖冲突，继续进行安装，

npmV7版本开始不会自动进行忽略，需要用户手动输入命令。

解决的方法就是command with --force，或者--legacy-peer-deps

--force 无视冲突，强制获取远端npm库资源（覆盖之前）

--legacy-peer-deps 忽视依赖冲突,继续安装（不覆盖之前）

因此输入：npm install --force 或者 npm install --legacy-peer-deps即可解决。
