######尝试了执行：
git config --global url."https://github.com".insteadOf git://github.com
git config --global --unset http.proxy
git config --global --unset https.proxy
git config --global url."https://".insteadOf git://
后再次报错，内容与文章开头相同
C:\Users\jalchu\WebstormProjects\vue-element-admin>git config --global url."https://".insteadOf git://
重新安装 C:\Users\jalchu\WebstormProjects\vue-element-admin>npm install 看这个报错解决一样 https://blog.csdn.net/baidu_30809315/article/details/86520093
望采纳！！！
可尝试更换 npm 镜像源。
另外你的错误日志是无法连接到 github.com，可尝试用代理，用梯子，来解决网络问题。
望采纳！！！ 可以使用淘宝npm源测试下。
npm使用淘宝镜像源
单次使用
npm install koa --registry=https://registry.npm.taobao.org/
永久使用
配置淘宝镜像源
npm config set registry https://registry.npm.taobao.org/
或者安装cnpm
npm install cnpm -g --registry=https://registry.npm.taobao.org/
使用下试试
npm/cnpm install koa
解决访问github.com超时问题
使用
1、增加proxy
2、增加hosts配置
针对2、利用IPaddress查github的IP地址
配置hosts文件，修改后ipconfig /flushdns
