MongoDB node.js驱动程序安装是否需要Python？

Question

我试图在Windows 10上为Nodejs安装mongodb驱动程序,并获得有关Python的以下错误.

Python是预先评估的吗？而且它也只期望Python版本2.5到3.0.在Python之上它一直要求其他MS Visual Studio 2008或MS SDK/.Net安装？是否需要所有这些作为预先评估.

C:\Jay\M101JS>npm install mongodb

更新:

安装Python 2.7和Visual Studio Express(免费)后再次尝试,现在得到以下错误,

C:\Jay\MongoDb\M101JS>npm install mongodb

Answer 1

是的,Python是必需的.

您需要安装2.7版.您还需要将PYTHON环境变量设置为例如c:\python27\python.exe(确保可以从命令行运行env p)

您需要安装Visual Studio(C++),免费的Express版本可以.

在您的Visual Studio版本上降级,您必须将此参数添加到您的npm install命令:

npm install --msvs_version=<version>其中<version>可以是2012,2013或2015例如.

引入了node-gyp依赖性,Node.js MongoDb驱动程序使用该依赖性.可以在此处找到Windows的安装说明(显示的详细信息略多于此答案).
