求助~鸿蒙系统windows环境搭建（hpm-cli安装失败）！
系统win10，执行命令“npm install -g @ohos/hpm-cli”，报错如下：
npm ERR! code EEXIST
npm ERR! path C:\Users\jay\AppData\Roaming\npm\node_modules\@ohos\hpm-cli\bin\hpm
npm ERR! dest C:\Users\jay\AppData\Roaming\npm\hpm

npm ERR! File exists: C:\Users\jay\AppData\Roaming\npm\hpm

The terminal process "C:\WINDOWS\System32\WindowsPowerShell\v1.0\powershell.exe -Command npm install -g @ohos/hpm-cli" terminated with exit code: 1.
太困难了，终于安装成功了。
原因：
1.官方提供的网址连接超时，更换为阿里源npm config set registry https://registry.npm.taobao.org；
2.本地可能存在旧版本hpm，按提示删除已存在的hpm，再执行npm install -g @ohos/hpm-cli；
3.安装成功，hpm -V会显示版本号；
