2、检查 NPM 代理设置，其值为：https://127.0.0.1:8888/

PS E:\wwwroot\shopify-theme> npm config get proxy
https://127.0.0.1:8888/

3、决定删除掉 NPM 代理设置。

PS E:\wwwroot\shopify-theme> npm config rm proxy
PS E:\wwwroot\shopify-theme> npm config rm https-proxy
PS E:\wwwroot\shopify-theme> npm config get proxy
null
PS E:\wwwroot\shopify-theme>

4、再次执行安装命令，不再报错。

PS E:\wwwroot\shopify-theme> npm install -g @shopify/cli@3.32.0 @shopify/theme@3.32.0
npm WARN deprecated @oclif/screen@3.0.4: Deprecated in favor of @oclif/core
