基本聊天應用程序使用Socket.io和Node js創建

Question

我剛剛嘗試使用以下指令創建基本聊天應用程序http://socket.io/get-started/chat/。

當我試圖運行npm install --save socket.io

我收到以下錯誤。如何解決以下錯誤：

npm WARN package.json socket-chat-example@0.0.1 No repository field. 
npm WARN package.json socket-chat-example@0.0.1 No README data 
npm WARN package.json socket-chat-example@0.0.1 No license field.

你試過安裝node-gyp和g ++嗎？

npm install -g node-gyp 

和g ++

apt-get install g++
