NPM - 无法安装 socket.IO [英] NPM - Can't install socket.IO

问题描述

我正在尝试使用 npm 在 windows 上安装 socket.io，以便在 nodeJS 服务器上使用.

I am trying to install socket.io on windows with npm for use on a nodeJS server.

首先，当我输入npm install socket.IO"时，我在日志中出现了一个关于 python 和 node-gyp 的错误.我安装了python 2.7.3并设置了环境变量.

First, when I typed "npm install socket.IO" i had an error in the log saying something about python and node-gyp. I installed python 2.7.3 and set the environment variables.

现在我遇到了一个新错误，它与visual studio有关(VS与npm有什么关系?与编译器有关?).

Now I got a new error, which has something to do with visual studio (what the hell does VS have to do with npm ? Is it about the compiler? ).

错误和这里一样 npm 安装某些软件包(sqlite3、socket.io)在 Windows 7 上失败并显示错误 MSB8020但是，当我在答案中使用该选项而不是错误时，它会告诉我有关可能的数据丢失 (c4267) 的一些信息，但不会记录任何错误.

The error is the same as here npm install for some packages (sqlite3, socket.io) fail with error MSB8020 on Windows 7 But when I use the option in the answer instead of the error it tells me something about a possible data loss (c4267) but doesn't log any error.

然后当我启动我的应用程序时，它告诉我仍然找不到模块 socket.io这可能来自什么?

Then when I start my app, it tells me cannot find module socket.io still What could this come from ?

哦，当我执行 npm config get root 时，它告诉我未定义"是否与它有关?我应该全局安装模块还是本地安装模块?

Oh and also when i do npm config get root it tells me "undefined" could it have anything to do with it ? Should I install the modules globally or locally ?

推荐答案

Socket.IO 的依赖树中至少有一个包是 C/C++ 插件，需要在安装时在系统上编译.而且，由于它是一个依赖项，如果安装不成功，Socket.IO 也不会.

At least one of the packages in Socket.IO's dependency tree is a C/C++ addons which needs to be compiled on your system as it's installed. And, since it's a dependency, if it doesn't succeed in installing, neither will Socket.IO.

为了启用跨系统编译，Node.js 使用 node-gyp 作为它的构建系统.您需要将其安装为全局包:

To enable cross-system compilation, Node.js uses node-gyp as its build system. You'll need to have it installed as a global package:

npm install -g node-gyp

以及安装其依赖项.删减版:

• Python 2
• C/C++ 编译器/构建工具
  • 对于 Windows，Microsoft Visual Studio 2013(C++ 或 Windows 桌面)(速成版)
    • 对于 64 位，可能需要 Windows 7 64 位 SDK

    然后，您应该能够将 Socket.IO 作为本地包安装，以便您可以要求它:

    Then, you should be able to install Socket.IO as a local package so you can require it:

    npm install socket.io
