这有点旧，但是我遇到了要求，所以这是我想出的解决方案。
问题：
我们的开发团队维护着许多要迁移到AngularJS / Bootstrap的.NET Web应用程序产品。VS2010不能轻易地用于自定义构建过程，而我的开发人员通常会在产品的多个版本上进行工作。我们的VCS是Subversion（我知道，我知道。我正在尝试迁移到Git，但我讨厌的营销人员要求很高），并且一个VS解决方案将包含几个单独的项目。我需要我的员工采用一种通用的方法来初始化其开发环境，而不必在同一台计算机上多次安装相同的Node包（gulp，bower等）。
TL; DR：
需要“ npm install”来安装全局Node / Bower开发环境以及.NET产品的所有本地必需的软件包。
仅在尚未安装全局软件包的情况下才应安装。
必须自动创建指向全局包的本地链接。
解决方案：
我们已经有一个由所有开发人员和所有产品共享的通用开发框架，因此我创建了一个NodeJS脚本来在需要时安装全局软件包并创建本地链接。脚本位于相对于产品基本文件夹的“ .... \ SharedFiles”中：

现在，如果要为开发人员更新全局工具，则更新“ packages”对象并签入新脚本。我的开发人员将其签出并使用“ node npm-setup.js”运行它，或者通过正在开发的任何产品的“ npm install”运行它来更新全局环境。整个过程需要5分钟。
此外，要为新开发人员配置环境，他们必须首先仅安装Windows版NodeJS和GIT，重新启动计算机，签出“共享文件”文件夹和任何开发中的产品，然后开始工作。
.NET产品的“ package.json”在安装之前会调用以下脚本：
{
"name" : "Books",
"description" : "Node (npm) configuration for Books Database Web Application Tools",
"version" : "2.1.1",
"private" : true,
"scripts":
{
"preinstall" : "node ../../SharedFiles/npm-setup.js links",
"postinstall" : "bower install"
},
"dependencies": {}
}
笔记
编辑1/29/16
npm-setup.js上面更新的脚本已被修改如下：
var packages现在，“版本”中的软件包是npm install在命令行上传递给“软件包”的值。进行了更改，以允许从注册的存储库以外的其他位置安装软件包。
如果该软件包已经安装但不是要求的软件包，则将删除现有软件包并安装正确的软件包。
由于未知原因，npm在执行安装或链接时会定期抛出EBUSY错误（-4082）。将捕获此错误，并重新执行命令。该错误很少再次发生，并且似乎总是可以清除。
"preferGlobal": true在package.json内设置模块。
