根据天猪的公告，原淘宝npm域名 http://npm.taobao.org 和 http://registry.npm.taobao.org 将在 2022.06.30 号正式下线和停止 DNS 解析。

域名切换规则：

http://npm.taobao.org => http://npmmirror.com
http://registry.npm.taobao.org => http://registry.npmmirror.com

tyarn 可能会受影响，现在访问淘宝 NPM 已经会自动 301 跳转到 npmmirror.com 新域名

com.exe return:

这是报的什么错？我用的是淘宝镜像的 registry
