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)
    at Object.<anonymous> ([..]\node_modules\node-sass\lib\index.js:14:35)

    at Object.<anonymous> ([..]\node_modules\gulp-sass\index.js:187:21)
    at Module._compile (module.js:397:26)

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。

在删除node_modules或清理缓存(这会花费时间)之前，尝试运行

NPM重建node-sass——force

在项目文件夹中。就像我的一样，你的问题得到解决的几率很高。如果不成功，试试下面的方法:

npm cache clean --force 
rm -rf node_modules 
npm install 
npm rebuild node-sass

npm start

Windows 10 This was a fun one for me... In order to resolve it I had to do all of the following.. 1.) Apparently node-sass isn't supported by some of the more recent versions of Node.js so I had to Uninstall Node-v 12.14.1, and delete the nodejs directory in C:/Program Files. 2.) Reinstall a earlier version of Node (for me 10.16.2 worked). NOTE: I had initially downloaded the x86 version so if your System is x64 download the x64 verison... 3.) From here I had to delete my entire project and re-clone it. After this things ran fine.

除了Abdelsalam Megahed的简短回答，其中包含了大部分解决方案……(也就是说，先看他的答案，然后做这件事)

在遵循Abdelsalam建议的四个简短步骤之后，我运行npm run dev并收到以下消息:

Failed to load C:\path\tsconfig.json: Missing baseUrl in compilerOptions

最后一步是编辑tsconfig。在"compilerOptions":下添加"baseURL": "."，像这样:

"compilerOptions": {
    "baseUrl": ".",
    etc etc etc

问题到这里就解决了。

注意:可能需要硬重置CtrlF5页面来查看更改(即使没有恶魔)。

对我有用:

只需删除node-sass文件夹并运行npm install。

删除“node_modules”文件夹。 重新安装依赖项。(npm)
