node.js - 如何在 Ubuntu(Amazon EC2 实例)上安装 websocket-node？

Question

我一直在寻找，但我找到的解决方案都没有帮助。我想做的就是

npm 安装 websocket

我在此找到的大多数帖子都表明人们缺少 make、gcc、g++ 或 python，但我拥有所有这些。我的python是v2.7.6。

为了解决上述 npm 失败的问题，我已经做到了，

sudo npm --websocket:verbose --nodedir=/home/ubuntu/node install -g websocket

但是当我尝试时，我得到:

ubuntu@ip-172-31-20-33:~$ sudo npm --websocket:verbose --nodedir=/home/ubuntu/node install -g websocket

> websocket@1.0.8 install /usr/local/lib/node_modules/websocket
> node install.js

[websocket v1.0.8]
    Native code compile failed!!
    Please note that this module DOES NOT REQUIRE the native components
    and will still work without them, though not quite as efficiently.

    On Windows, native extensions require Visual Studio and Python.
    On Unix, native extensions require Python, make and a C++ compiler.
    Start npm with --websocket:verbose to show compilation output (if any).
websocket@1.0.8 /usr/local/lib/node_modules/websocket

有人知道发生了什么吗？

我注意到 websocket-node 更新已经有一段时间了。我想知道 websocket-node 是否与 node v0.13.0-pre 不兼容？我什至应该使用 v0.13.0-pre 吗？

最终，我只想能够从同一端口上的同一 node.js 实例运行 http/https 和 ws/wss。 websocket Node seems able to handle fine ，但不清楚如何处理 ws 模块(它适用于只做普通的旧 ws)。

任何有关如何使用 ws 的指示都与找出 websocket 出了什么问题一样好。

Answer 1

看来问题确实是与 Node v0.13.0-pre 不兼容。我得到了源代码并安装了 Node v0.10.32 然后做了

sudo npm --websocket:verbose --nodedir=/home/ubuntu/node-v0.10.32 install -g websocket

和 websocket 安装正确。
