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

问题描述

我试图在具有npm的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，当我键入"npm install socket.IO"时，日志中出现错误，提示有关python和node-gyp的信息.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，这与Visual Studio有关(VS与npm有什么关系?与编译器有关吗?).

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? ).

错误与此处相同

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 这可能是什么?

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时，它会告诉我未定义"，这与它有什么关系吗? 我应该在全局还是本地安装模块?

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依赖树中的至少一个软件包是 C/C ++插件，该插件在安装时需要在您的系统上进行编译.而且，由于它是一个依赖项，如果安装失败，那么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 作为其构建系统.您需要将其作为全局软件包安装:

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

以及已安装其依赖项.精简版:

• Python 2
• C/C ++编译器/构建工具
  • 对于Windows，Microsoft Visual Studio 2013(C ++或Windows桌面)(Express版)
    • 对于64位，可能需要Windows 7 64位SDK
    • Python 2
    • C/C++ Compiler / Build Tools
      • For Windows, Microsoft Visual Studio 2013 (C++ or Windows Desktop) (Express edition)
        • For 64-bit, may need Windows 7 64-bit SDK

        然后，您应该能够将Socket.IO作为本地软件包安装，这样您就可以require了:

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

        npm install socket.io
