WARNING: The Python 'six' package not found.

after installing NativeScript on my macos using ruby -e "$(curl -fsSL https://www.nativescript.org/setup/mac)" I ran into error while typing tns doctor which tells me WARNING: The Python 'six' package not found. and when I trying to install six by pip install six I get the message : Requirement already satisfied: six in /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python (1.4.1) so there is six installed but yet it wont let me move on because of it

Just reproduced the issue on brand new macOS High Sierra.

Here is what happens: tns doctor fails because six is not found. This happens because python -c "import six" fails. On the other side pip install six says Requirement already satisfied.

Here is how I was able to workaround it:

sudo pip install --upgrade pip
pip install --user --upgrade matplotlib
pip install six

@obiwankenoobi what is your OS perhaps El Capitan? If so try this solution

pip install --ignore-installed six
