Windows环境下npm install常见错误

Windows环境下npm install安装包依赖时,常出现一些错误,下面为个人解决办法:

错误一

缺少python环境:

G:\nodejs\moviesite\node_modules\bcrypt>if not defined npm_config_node_gyp (node
"D:\Program Files\nodejs\node_modules\npm\bin\node-gyp-bin\\..\..\node_modules\
node-gyp\bin\node-gyp.js" rebuild ) else (rebuild)

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

错误二

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

如图:

需要安装Microsoft Visual Studio Express 2013 for Windows Desktop 
(版本应该不限制,我安装的是上边的版本)

安装成功,但是出现了警告,警告不影响bcrypt的使用
