我是nodejs的新手。 当我要安装blueimp-file-upload-expressjs时，会出现以下错误。
D:\WorkShop\Express\zipzap>npm install blueimp-file-upload-expressjs --save

如何安装并使用此插件？也无法理解什么是实际错误。 我正在研究nodejs。那为什么要求python路径？
答案 0 :(得分：0)
@Dipankar Naskar：那为什么要求python路径？
因为Node.js是用GYP构建的 - 用Python编写的跨平台构建工具。还有一些其他构建步骤在Python中实现。因此，从源代码构建节点需要Python。
@Dipankar Naskar：如何安装它并使用这个插件？
这是几乎情况下的解决方案。
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。
[仅限Windows 7]需要.NET Framework 4.5.1
安装Python 2.7或3.6，并将其添加到PATH，npm config set python python2.7
启动cmd，npm config set msvs_version 2015 --global（每次都代替npm install [package name] --msvs_version=2015。）
SO MUCH npm install
注意：对于您的问题，您只需安装Python，将其添加到PATH，npm config set python python2.7。
