卸载和安装sass包对于手动过程很有效，但对于自动部署/CI/CD，你需要更通用的方法。对我来说，适用于不同环境的Continuos部署是:

在部署前使用rimraf删除旧的node_modules rimraf node_modules 更新npm包中的sass包。Json &提交到源代码控制。

对于下一次部署，它将自动刷新所有环境的sass。

我，只是为了添加我在Windows上，我通过删除我用户的node_module文件夹中的node-sass条目来解决我的问题(C:/users/$username/node_modules/node_sass)

重建和删除node_sass之前什么都没有做，现在我的问题解决了!

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.

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.

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。

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

对我来说，当我运行npm安装时，它审计了已安装的包，并显示“发现1个高严重漏洞”，并通过运行

npm audit fix

成功了。如果能帮助到别人就发布。

更新:共享错误日志:

它确实要求我这么做

Run `npm rebuild node-sass` to download the binding for your current environment.
