解决方法

是因为npm缓存目录去缓存了个 _git-remotes 目录
windows路径：C:\Users\youname\AppData\Roaming\npm-cache
删除_git-remotes 再继续npm install。

如果总是中断，可以尝试设置代理试试。
(自备的Shadownsock代理地址http://127.0.0.1:1080)
git config –global http.proxy http://127.0.0.1:1080
git config –global https.proxy https://127.0.0.1:1080
git config –global http.proxy ‘socks5://127.0.0.1:1080’
git config –global https.proxy ‘socks5://127.0.0.1:1080’
取消代理
git config –global –unset http.proxy
git config –global –unset https.proxy
