In case the answer(s) provided doesn't work for you, here are some tips you can follow in order to mitigate related problems for windows OS.
NOTE: If you already tried installing the build tools via npm command with no success, it is probably a good idea to delete everything before applying any of the tips below.
You can find the build tools here and just delete the folders (but I don't know if they are installed somewhere else):
C:\Users\'yourUser'\.windows-build-tools\
C:\Users\'yourUser'\AppData\Roaming\npm\node_modules\windows-build-tools
After ensuring that the folders specified above are deleted, then you can try applying any of the following tips.
First Tip:
Run CMD or PowerShell as Administrator
Install node-gyp using the following command: npm install -g node-gyp
Download and install windows build tools manually from this link: Windows_Build_tools
Download and install Python 2.7
Register Microsoft Visual Studio version to npm using the following command: npm config set msvs_version <your msvs_version e.g. 2017>
Register the path of python executable file to npm using the following command: npm config set python <the path to python executable file>
Second Tip (RECOMMENDED)
Run CMD or PowerShell as Administrator
Install windows-build-tools with the python-path directly using the following command: npm --add-python-to-path='true' install --global --production windows-build-tools
You can run the following command: npm config set python <the path to python executable file>, in order to be sure that npm is pointing to the correct path of python executable file.
In order to use this command, you can find the python path here (i.e. after running the command in the previous step): C:\Users\<your_user_name>\.windows-build-tools\python27
More information or description about node-gyp can be found here: node-gyp
More information about possible windows build tools issues can be found in the following links:
https://github.com/felixrieseberg/windows-build-tools/issues/47
https://github.com/felixrieseberg/windows-build-tools/issues/56
Additional Note: Some people tend to have spaces in their project path names whereas, some tools don't handle spaces in path names well. You can get more info here: https://github.com/nodejs/node-gyp/issues/809
Hope this solves your problem.

Any error that points to a syntax error while executing python code is due to the version of python (python v3 or v2) executable that executes the python script file. In this case specifically, npm is trying to build few node modules because binaries for those modules are not published on internet. Hence when an incorrect version of python compiler (or interpreter as some would say) is loaded and used to build python code, you will see syntax error.
The fix to such problem is not to uninstall python, because you may need both versions of python for different purposes. Simply add python v2 path before python v3 if you have both or if you do not have python then install python v2 and add the location to environment variable as shown below. Hope this solves the issue.
Node.js is built with GYP — cross-platform built tool written in Python. Also some other build steps are implemented in Python. So Python is required for building node from source.
But you also need Python for building native addons.
