我是nodejs的新手。当我要安装 blueimp-file-upload-expressjs 时，出现以下错误。

D:\WorkShop\Express\zipzap>npm install blueimp-file-upload-expressjs --save
npm WARN deprecated lodash-node@2.4.1: This package is discontinued. Use lodash@^4.0.0.

如何安装和使用这个插件？也无法理解实际的错误是什么。我正在做nodejs。那为什么它要求 python 路径？

Answer 1

@Dipankar Naskar: then why is it asking for python path??

因为 Node.js 是用 GYP 构建的— 用 Python 编写的跨平台构建工具。另外一些其他构建步骤也是用 Python 实现的。因此需要Python来从源代码构建 Node 。

@Dipankar Naskar: How to install it and use this plugins?

这是几乎情况的解决方案。

Node.js 的配置步骤现在应如下所示:

安装VC++ Build Tools Technical Preview ，选择自定义安装，然后选择 Windows 8.1 和 Windows 10 SDK。

💡 [Windows 7 only] requires .NET Framework 4.5.1

安装Python 2.7或3.6，并将其添加到您的PATH，npm config set python python2.7

启动cmd，npm config set msvs_version 2015 --global(这代替了每次npm install [package name] --msvs_version=2015。)

太多了 npm install 🎉

注意:对于您的问题，您只需安装Python，将其添加到您的PATH，npm config set python python2.7。
