Error while running gulp, Missing binding, node-sass couldn't find a binding

When I run the gulp command, I get this error:

throw new Error(errors.missingBinary());
      ^

Error: Missing binding C:\Program Files (x86)\EasyPHP-Devserver-17\eds-www\Project\node_modules\node-sass\vendor\win32-x64-48\binding.node
Node Sass could not find a binding for your current environment: Windows 64-bit with Node.js 6.x

Found bindings for the following environments:
  - Windows 64-bit with Node.js 6.x
  - Windows 64-bit with Node.js 14.x

This usually happens because your environment has changed since running `npm install`.
Run `npm rebuild node-sass` to download the binding for your current environment.

I have tried npm rebuild node-sass and uninstalling and reinstalling node-sass and all node_modules many times.

I am in the node version: 6.10.2, npm:6.14.14, gulp CLI version 1.2.2, Local version 3.9.1. Windows 10, x64. Please help.
