create_android_makefiles fails - No Module named GN-scraper

[barak14]

• Project: Android makefile creation
• Version: NodeJS mobile 0.3.4 (latest git master)
• Mobile device: AOSP
• Mobile OS and version: Android Pie 9
• Development Node.js: 12.9.0
• Development platform: WSL2 Ubuntu 20.04

I can successfully build the node libraries using the android-configure and then build but when I attempt to run
tools/create_android_makefiles I receive the following output and it fails to complete:

user@pc:~/sources/nodejs-mobile$ tools/create_android_makefiles

I have run the lunch command for my target
I have tried Python2 and Python3 (3 fails at ForEachFormat). Is there something missing that I can't see :)
The python files seem to be there and when I run this a pyc file is created for each of these files under v8_gypfiles
