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

Solution 1:
so this happened to me on windows recently. I fix it by following the following steps using a PowerShell with admin privileges:
deletenode_modules folder
running npm install --global windows-build-tools with administrative privilege. (in my case need restart – and restart without ask!!!)
reinstalling node modules or node-sass with npm install
This is exactly the right answer. npm install --global windows-build-tools installs Python 2.7, and installs it globally (so you don’t have to re-install on a per-project basis). It fixes the “can’t install SASS” problem. NOTE: On windows, you must run your npm command prompt as “Administrator”.

Solution 2:

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
