Node.js: Python not found exception due to node-sass and node-gyp

The error message means that it cannot locate your python executable or binary.

In many cases, it's installed at c:\python27. if it's not installed yet, you can install it with npm install --global windows-build-tools, which will only work if it hasn't been installed yet.

Adding it to the environment variables does not always work. A better alternative, is to just set it in the npm config.

npm config set python "C:\Python27\python.exe"

so this happened to me on windows recently. I fix it by following the following steps using a PowerShell with admin privileges:

1. delete node_modulesfolder
2. running npm install --global windows-build-tools with administrative privilege. (in my case need restart - and restart without ask!!!)
3. reinstalling node modules or node-sass with npm install

You need to follow the below steps to fix the error:

    1: DELETE node_modules
    2: npm install node-sass@<version-as-per-below-table>
    3. npm install

Every node-sass version corresponds to a specific Node.JS build.

Below is a quick guide for minimum and maximum support supported version of node-sass (Check updates to below table here) :

---
