Initialization/Installation Problem

[pfliegster]

Hello,

Running under Ubuntu 16.04LTS, Python 2.7.12, pip 9.0.0; I'm having a problem running the "fusesoc init" command in the installation instructions. I suspect that something got screwed up during installation. Here are the errors I receive:

VirtualBox:~/fusesoc$ fusesoc init
Traceback (most recent call last):
  File "/usr/local/bin/fusesoc", line 5, in <module>
    from pkg_resources import load_entry_point
  File "/usr/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 2927, in <module>

    working_set = WorkingSet._build_master()

    return cls._build_from_requirements(__requires__)
  File "/usr/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 650, in _build_from_requirements
    dists = ws.resolve(reqs, Environment())
  File "/usr/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 834, in resolve
    raise VersionConflict(dist, req).with_context(dependent_req)
pkg_resources.ContextualVersionConflict: (attrs 16.2.0 (/usr/local/lib/python2.7/dist-packages), Requirement.parse('attrs<16.1.0'), set(['okonomiyaki']))
VirtualBox:~/fusesoc$

In fact, running any of the fusesoc commands seem to fail similarly, so I think something went wrong during my install or update (the output from the sudo pip install -e . phase says I have fusesoc 1.5).

Another note: when running the "sudo pip ..." commands, it kept giving me an error about permissions and suggested I use the "sudo -H ..." -H flag option. Which I did, so perhaps something got out of whack here. Any help correcting my install is greatly appreciated :-)

Actually, this isn't your fault, or really my fault either :)

It's the stupid pip package manager that fails to install the correct version of one of the dependencies. You will hopefully get around this by running sudo pip install -I attrs==16.0.0. There is some more info here

Let me know if that works

Excellent! Thank you very much Olof! That fixed my problem.
