Python env variable exists and specify path to C:\Program Files (x86)\Python36-32\python.exe.
npm config set python 'C:\Program Files (x86)\Python36-32\python.exe' or npm install --python= 'C:\Program Files (x86)\Python36-32\python.exe' give the same result.

node v8.9.0
npm 5.5.1
$ python -V
Python 3.6.1
