Error on the "Install the Ansible Galaxy roles" step of Trellis installation (Newbie)


I tried to make my first installation of Trellis, Bedrock and Sage following the docs and i have a problem during the Trellis installation during step 4 (“Install the Ansible Galaxy roles”).

The result to the command:
$ ansible-galaxy install -r requirements.yml

is this error message:

ERROR! Unexpected Exception: ‘ImportError’ object has no attribute 'message’
the full traceback was:

Traceback (most recent call last):
File “/Library/Frameworks/Python.framework/Versions/3.5/bin/ansible-galaxy”, line 73, in
mycli = getattr(import(“ansible.cli.%s” % sub, fromlist=[myclass]), myclass)

During handling of the above exception, another exception occurred:

I have installed ansible and i’m using Os X 10.11.3.

Thanks for your help!

Ansible only works with Python 2 and from your traceback it looks like 3.5 is being used? Maybe it’s the default on OS X 10.11 now. My guess is that you need to install Python 2.x.

I got a similar error on OX El Capitain:

Hi. in my case I have Python 2.x running, but I got the error that I put bellow, any thoughts?

Sorry, but I’m not really sure. This is more of a Python issue on your local machine than an Ansible or Trellis issue. You could try re-installing Python through Homebrew.

As long as you have python (not python3) installed via homebrew,I would venture a guess that either

  1. Homebrew is not at the “top” of your PATH environment variable. Fix this within ~/.profile or ~/.bash_profile with the line like: export PATH=/usr/local/bin:/usr/local/sbin:$PATH, or
  2. pip setuptools may be an old version, which can be remedied (and everything else listed & updated) with:
    $ pip list --outdated
    $ pip install --upgrade pip setuptools
    $ pip freeze --local | grep -v '^\-e' | cut -d = -f 1 | xargs pip install -U

I didn’t install any Python version, Python is default in my machine:

~ python
Python 2.7.10 (default, Oct 23 2015, 19:19:21)
[GCC 4.2.1 Compatible Apple LLVM 7.0.0 (clang-700.0.59.5)] on darwin

Well then…get homebrew fully setup and install (at least) python & ansible installed with brew install. Then tell us what happens.

Stay away from sudo installs/updates into your system if you can help it. Leave that to Apple.

It’s now fixed but in a wird way. After a long digg, i finally managed to upgrade the python setuptools with this:

pip install --upgrade setuptools --user python

the wird stuff is that I got the same setuptools version (1.1.6) but now everything works fine with the Ansible Galaxy roles…

thanks for you support!


Thanks everybody for your answers!

I’ll try a few things based on your feedback and get back to you if i solve it… or not :wink:

Yes, that fixed it for me. Thanks!

Congratulations, that’s great news!

I would like to strongly suggest to you (and anyone else reading this thread) to get homebrew onto any Macintosh you plan on using Trellis with.

Updating OS X system components is a no win, zero sum game. At best, if you are lucky, you will likely need to run these upgrade commands again when a new OS update comes out. At worst, you break system functionality and sometimes are almost forced to do global/sudo installs of ansible, npm, etc.

A few years ago, I did not use homebrew and had horrible experiences with OS X updates overwriting multiple ruby packages. I would never wish a forced OS X re-install to anyone working on deadlines

based on your feedback, after a long struggle, Google searching, reading online tutoriels and fiddling in the Terminal, i managed somehow to pass successfully that step 4 of the Trellis install!

i resolved my problem by:

  • uninstalling Python 3.5 (and Ansible which i had previously installed in it), leaving only the Python version of El Capitan
  • installing pyenv via homebrew
  • installing Python 2.7.11 and 3.5.1 via pyenv
  • setting Python 2.7.11 as global via pyenv
  • re-installing Ansible via pip in the Python 2.7.11 managed by pyenv

Once everything correctly installed, it just worked (and i learned a few tricks, still a newbie though).

Next step: configuring the WordPress sites, wish me luck :wink:


I ran into a similar issue on vagrant up, after I upgraded pip. I upgraded setuptools but was unable to upgrade asnisble. Wrote the ansible upgrade command like this and it worked fine.
sudo -H pip install --upgrade ansible --user python

It was working for me… until I install Homebrew… Now I’m stuck with this same issue, not sure how to proceed.

Do you know if the python/pip that you now have is via homebrew? You might want to start with which pip to make sure it is within a homebrew directory (/usr/local/bin/) and then follow the 3 pip list/install/freeze commands from my April 30 post. Separately, you can update all of homebrew with these three commands: brew update; brew upgrade --all; brew doctor

Yes it’s good!

Everything is up to date.

The freeze command brings an error message :slight_smile:

Did you copy/paste the whole last line?
pip freeze --local | grep -v '^\-e' | cut -d = -f 1 | xargs pip install -U

That last OSError line is a concern as is referencing the OS (and not homebrew) system. I don’t even have a a thought as to a direction to point you in with that one. :confused:

Yes I did :wink:

I did a “doctor” and I have unlinked directories apparently, trying some fixes… Not sure where I’m going ^^°

Currently reading this :

So the Freeze is still bringing an error message BUT the ansible galaxy role has been installed and vagrant up is working now :slight_smile:

Maybe after a sudo pip upgrade?
