Hello @amramtamir, what is your CLI installation method?

[amramtamir]

Hi,
brew install azure-cli

@marstr, can you please take a look?

Investigating now

I need more information, @amramtamir! When I run brew install azure-clion my Mac running 10.14.4, all seems well. Is there anything special about your machine? Have you installed Python on your machine outside of using Homebrew?

[amramtamir]

Hi @marstr ,
Nothing special on my Mac - I used brew to install python.
I also tried to:
reinstall azure-cli, python, brew, Six package.

This might help? https://stackoverflow.com/questions/27630114/matplotlib-issue-on-os-x-importerror-cannot-import-name-thread

A comment below the top answer says updating your version of six might help

[amramtamir]

Hi @marstr
It seems to work!
I have done these steps:
opened python from the terminal
import six
print six.file

the output showed that the six.pyc and six.py was on my home path
I ran rm -rf six.*
and the "az" command is now working :)

This is troublesome to me, as my hope was that using a Virtualenv in the Homebrew installer would isolate us from these sorts of problems.

@lmazuel, my take away from this is that in addition to invoking the python inside of the virtualenv, I should be invoking it with the -s flag. Do you think that's the right conclusion?

[lmazuel]

@marstr venv should not load any system or user system directory by default, so that option should be useless. If you're able to show me an example with venv and user directory where "-s" makes a difference I'm curious :)
That being said, it seems the story is more subtle:
pypa/pip#4141
pypa/pip#5702

I'm going to close this out as a one-off error for now. However, if other people stumble on this and it needs a fix from us, I'm happy to open it back up.
