Node gyp error even after setting the environment variable

I have set my environment variable as PYTHON=D:\Program Files\Python36-32\python.exe, but still I get the below error. This is while doing npm install node-gyp --save. I am not able to find a solution for it. My python version is python-3.5.6

gyp ERR! configure error gyp ERR! stack Error: Can't find Python executable "D:\Program Files\Python36-32\python.exe", you can set the PYTHON env variable. gyp ERR! stack at PythonFinder.failNoPython (C:\Program Files\nodejs\node_modules\npm\node_modules\node-gyp\lib\configure.js:454:19) gyp ERR! stack at PythonFinder.

Any help would be appreciated. Need a perfect solution for removing this error.

Thanks
