pip install blockstack fails osx 10.11.4 about stacks.js HOT 8 CLOSED

updating python and pip got past these errors:

brew install python
pip install --upgrade pip

but now I see:

ImportError: No module named utilitybelt

from stacks.js.

Can you post more details about the 'utilitybelt' error? Thanks!

FYI, I'm seeing a similar problem,.. with slightly different version numbers... under OS X 10.11.5
So although the "sudo pip install blockstack" succeeds,
running blockstack on my OS X failed :(... but then succeeded (jump to EOF). :)

What ultimately worked for me was to do this:

sudo rm -rf /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/six*
sudo pip install six
Successfully installed six-1.10.0

yeah. success

A lot of these problems should be fixed in the new stable release (i.e. we don't rely on Twisted any longer). A new version of blockstack has been pushed to pip. Please re-open if you're still seeing problems.

Just for fun, I've returned on a fresh system a year later,.. I am now on a freshly installed (not upgrade) 10.12.4. I just installed Brew. Then did the OS X installations, with no errors, from https://blockstack.org/docs.

BUT,.. running 'Blockstack',.. I get this:

So no... the new release doesn't appear to be an improved experience.
Just sayin.

@koppenhoefer thanks for sending the feedback! We're in the process of updating docs on our website (I just created this issue). The Blockstack Core README has the most recent installation guide.

From the log, I see that you're having issues with the fastecdsa installation. From the README, here are the instructions for macOS:

For macOS:

$ brew install gmp libffi openssl
$ sudo pip install --upgrade pip
$ sudo pip install blockstack --upgrade

Can you kindly try them out and see if this works? We're happy to help you with any issue. Apologies that you're having trouble. Blockstack Core packs a lot of complexity in it and getting it running smoothly on various distributions is a non-trivial issue. We're trying our best and have recently rolled out Azure images, AWS images, and docker images to try and make the process easier. Your feedback can help us improve more!

@muneeb-ali thanks for your swift and useful message.

YES, I confirm that your instructions fixed the issue for me. Thank-you!
