Common errors with NPM install under Windows environment

When the NPM install package is dependent on the Windows environment, some errors often occur, and the following is a personal workaround:

Error One

Missing python environment:

安装python解决，python(v2.7 recommended, v3.x.x is not supported)
Download: Http://www.python.org/ftp/python/2.7.3/python-2.7.3.msi

Error Two：

在此解决方案中一次生成一个项目。若要启用并行生成，请添加“/m”开关。 
MSBUILD : error MSB3428: 未能加载 Visual C++ 组件“VCBuild.exe”。要解决此问题， 
1) 安装 .NET Fram 
ework 2.0 SDK；2) 安装 Microsoft Visual Studio 2005；或 3) 如果将该组件安装到了 
其他位置，请将其位置添加到系统 
路径中。 [G:\nodejs\moviesite\node_modules\bcrypt\build\binding.sln] 
gyp ERR! build error

Need to install Microsoft Visual Studio Express for Windows Desktop
(The version should not be limited, I installed the above version)

The installation was successful, but there was a warning that the warning did not affect the use of bcrypt
