遇到此问题是因为 npm 配置了错误的代理设置，导致尝试通过本地未被监听的端口（127.0.0.1:31181）进行连接。以下是分步解决方案：

步骤 1：清除 npm 的代理配置

在命令行中执行以下命令，移除可能存在的代理设置：

bash 复制代码

npm config delete proxy
npm config delete https-proxy

步骤 2：检查环境变量中的代理设置

确保没有设置 HTTP_PROXY 或 HTTPS_PROXY 环境变量。在 Windows 的 CMD 中运行：

cmd 复制代码

set HTTP_PROXY
set HTTPS_PROXY

如果发现这些变量被设置，需要取消设置。在 CMD 中：

cmd 复制代码

set HTTP_PROXY=
set HTTPS_PROXY=

在环境变量中将 HTTP_PROXY和 HTTPS_PROXY 删除

重新npm install xxx 即可成功。
