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

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？也不能理解实际的错误是什么。我正在开发nodejs。那么为什么它会询问python路径？？

Answer 1

@Dipankar Naskar:那为什么它会询问python路径？

因为Node.js是用Python语言编写的跨平台GYP构建工具构建的。还有一些其他的构建步骤是用Python实现的。因此，从源代码构建节点需要使用Python。

@Dipankar Naskar:如何安装和使用这个插件？

这是几乎情况下的解决方案。

现在，Node.js的配置步骤应如下所示：

安装VC++ Build Tools Technical Preview，选择自定义安装，然后选择Windows8.1和Windows10SDK。

Windows7只需要.NET Framework 4.5.1

安装Python2.7或Python3.6，并将其添加到PATH npm config set python python2.7中

启动cmd，npm config set msvs_version 2015 --global (每次都是这样代替npm install [package name] --msvs_version=2015 )。

如此多的npm install

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