javascript - 安装socket.io返回(node-gyp重建2> builderror.log)|| (0号导出)

Question

运行命令 sudo npm install socket.io 时，我得到以下输出。

> ws@0.4.31 install /Users/xafar/Documents/projects/node/chat/node_modules/socket.io/node_modules/engine.io/node_modules/ws
> (node-gyp rebuild 2> builderror.log) || (exit 0)

我想知道，因为通常当我运行上面的命令 npm install Something 时，http GET 请求会发送到存储库以下载这些依赖项。 为什么我在这里没有得到相同的输出？如果这是一个错误，那么我该如何解决这个问题？

你看到的是C++编译。一些 npm 模块采用 C++，在模块安装过程中进行编译。
