node-sass runs an install script to download the required binary. If there are no environment variables, .npmrc variables or process arguments set then the binary is determined by using the current process platform, architecture and Node ABI version. Therefore, if you run node install in one application and then try to run node-sass in an application with a different platform/architecture/ABI, the binary won't have been downloaded. The solution is to manually download the binary or to fix the binary version using an environment variable (SASS_BINARY_NAME) or a .npmrc variable (sass_binary_name)

你可以在node-sass\lib\extensions.js中的getBinaryPath函数中看到这个逻辑

这招对我很管用: 纱线添加—force node-sass@4.14.1或纱线添加—force node-sass

在创建AspNetCore应用程序时，我在Visual Studio 2015 Community Edition中遇到了类似的错误:

Node Sass could not find a binding for your current environment: Windows 32-bit with Node.js 5.x
Found bindings for the following environments:
  - Windows 64-bit with Node.js 6.x
This usually happens because your environment has changed since running `npm install`.
Run `npm rebuild node-sass` to build the binding for your current environment.
    at module.exports ([..]\node_modules\node-sass\lib\binding.js:15:13)

您可以从上面的错误中看到，原因是nodejs绑定的版本不匹配。

Node Sass无法找到当前环境的绑定: Windows 32位，带有Node.js 5.x 为以下环境找到绑定: —Windows 64位，Node.js 6.x

我找到的解决办法是

安装windows版本的nodejs， 在外部网络工具中添加节点js (C:\Program Files\nodejs)的路径(参见Rob Scott的回答) 将nodejs路径移到$(path)上方。

我也有同样的问题。我在这里找不到任何合适的解决方案，所以我找到了自己的:

受到@ robb - scott解决方案和其他建议的启发，我们可以安装两个版本的Node.js，我去了C:\Program Files (x86)\nodejs，发现除了VS默认安装之外，我还安装了一个Node.js版本。

我的解决办法很简单:

进入工具>选项>项目和解决方案> Web包管理>外部Web工具 单击添加一个条目(右上角按钮块的最左边) 输入C:\Program Files (x86)\ nodejs，按Enter确认 把它放在清单的最上面 享受

可能Node.js在PATH变量中没有设置好，但这是我的工作非常快速的解决方案，我的2美分:)

我已经尝试了所有我能找到的方法。

我注意到那个文件夹有一些奇怪的行为。当我试图从VS终端“cd”到“node_sass”文件夹时，它告诉“文件夹未找到”，但在Finder中看到。

chmod从VS终端找不到文件夹，即使有'sudo'命令。

我已经从本地MacOs终端chmod-ed，刚刚与节点重建。
