如何安裝socket.io

我學習節點和socket.io，但我有一個問題，安裝socket.io 這裏就是我所做的：如何安裝socket.io

我創建了一個名爲它的文件夾nodejs
我創建嘗試使用這個命令來安裝插座app.js（無碼裏面還）
`NPM安裝socket.io

而且我得到了這些錯誤消息：

C:\wamp\www\nodejs 
λ npm install socket.io

當我檢查我的文件夾時，有一個node_modules文件夾，裏面是socket.io。看起來不錯，但是你能告訴我我是如何得到這些錯誤的？我需要重新安裝nodejs嗎？或者我在安裝套接字時錯過了一些部分？

見的重複[NPM - 無法安裝socket.IO（http://stackoverflow.com/questions/16469086/npm -cant-install-socket-io）以獲取詳細信息。安裝socket.io需要一些「構建」步驟，這些步驟需要某些工具超出npm。在這種情況下，您需要安裝適當版本的Python並安裝到您的路徑中，並且由於您在Windows上，您還需要一些C++構建工具。在Windows上安裝所有這些細節都在網上（我會看看我是否可以找到適當的鏈接）。 – jfriend00

應當指出的是，'故宮安裝socket.io'是成功的在這裏（你可以看到在輸出端的模塊樹），而插件的依賴關係（'UTF-8 validate'和'bufferutil'）是可選和socket.io將沒有他們的功能就好。擁有這些插件純粹是一種性能優勢。 – mscdex

stack Error: Can't find Python executable "python", you can set the PYTHON env variable.

確保你已經安裝了Python並設置了指向安裝位置的環境變量。

Socket.io安裝正確。

沒有正確安裝的是一些可選的依賴項。

npm WARN optional dep failed, continuing ...

爲什麼有的DEPS沒有被正確安裝的原因是很清楚

gyp ERR! stack Error: Can't find Python executable "python", you can set the PYTHON env variable.

所以你必須，如果你想安裝這些可選的依賴關係（你可能想）在你的系統中安裝Python。

安裝Python 2.7和運行

npm config set python C:\Python27\python.exe --global
