NativeScript 4 not working on CircleCI - setup script for macOS does not install python's six package

I have a simple CircleCI configuration which runs on MacOS that will checkout some test code, install NS dependencies as described in the docs and then builds the project for iOS.

This works perfectly when I use nativescript@3 but always fails when using nativescript@4 with the following error:

You are missing the nativescript-cloud extension and you will not be able to execute cloud builds. 
Your environment is not configured properly and you will not be able to execute local builds.
[...]
Exited with code 127

Any ideas what NS4 needs extra from NS3 ?

I’ve created PRs to address this issue in both repos. Thanks again for the help!

Hey @surdu , Thanks for providing the logs. Based on it I think the problem is that you do not have the python “six” package installed. Can you try installing it with pip install six and see if this will resolve the issue?
