v0.16.0 version installation issue

[bcostm]

I’ve tried to install yotta v0.16.0 and I got this error:

Can you help ? Thanks.

it looks like you're using easy_install. Try easy_install pip, then using pip to install yotta?

I tried with pip and I have the same errors...

[bcostm]

I discovered that the error does not come with the installation but when I type yotta --version or yotta --help. Do you have the same thing ?

OK thanks for the clarification. I can reproduce the problem, and I think #760 should work around it, but the root cause remains a mystery: for some reason when pkg_resources is resolving yotta's dependencies it's choking on pyasn1 (a dependency of requests[security]). I can reproduce this without yotta by running:

python -c "import pkg_resources; pkg_resources.require('requests[security]')"

However nothing related to that dependency has changed recently, so I don't know why this problem was first reported today.

(actually, looks like it was setuptools 20.6.6 which broke things, pip install setuptools==20.4 will revert to the previous published version, which works)

Fixed by https://github.com/ARMmbed/yotta/releases/tag/v0.16.1

Thanks for the patch for I still have the same problem after installing the v0.16.1.

But I tried pip install setuptools==20.4 after the v0.16.1 was installed and now it is ok.

OK thanks for reporting back.

setuptools v20.6.7 has now also been released, which reverts the underlying bug.
