python.exe Syntax issue - NPM

Question

I am having trouble when running Npm install. I get the following error:

gyp ERR! stack Error: Command failed: C:\Users\userxxx\AppData\Local\Programs\Python\Python37-32\python.EXE -c import sys; print "%s.%s.%s" % sys.version_info[:3];
gyp ERR! stack   File "<string>", line 1
gyp ERR! stack     import sys; print "%s.%s.%s" % sys.version_info[:3];

gyp ERR! command "C:\\Program Files\\nodejs\\node.exe" "C:\\Program Files\\nodejs\\node_modules\\npm\\node_modules\\node-gyp\\bin\\node-gyp.js" "rebuild"

I have added to my Path system variable the following:

C:\Python27\

In my user Path variable I have the following for Python:

C:\Users\userxxx\AppData\Local\Programs\Python\Python37-32\Scripts\
C:\Users\userxxx\AppData\Local\Programs\Python\Python37-32\
C:\Users\userxxx\AppData\Local\Programs\Python\Python37\Scripts\
C:\Users\userxxx\AppData\Local\Programs\Python\Python37\

Not sure what is going on here so any help appreciated!

I am seeing this problem on a fresh installation of node-js LTS 10.15.3. — rajah9

If the offending npm package is node-sass, there is now version 5.0.0 available, which runs on python3. npmjs.com/package/node-sass — wasserholz

The command you are attempting to run uses Python 2 syntax. It is incompatible with Python 3, so if you try to use that, you should get a syntax error.

Either upgrade the script to Python 3 (about time already), or fix the execution path so that it can be run with the obsolescent Python version.

Two solution we can try in this case

Downgrade Python to 2.x.
Install the packages using npm install --ignore-scripts

NOTE: This will cause npm to stop running scripts defined in the package.json
