-----------------

Running ansible 1.6 on a mac

Default python is 2.7.6 in /usr/local/bin/python .  That one can import httplib2.

[kbroughton@mb-kbroughton:lynx-ansible/21ct-ansible + (develop)] which python

/usr/local/bin/python

ansible seems to use /usr/bin/python, but that also can import httplib2

[kbroughton@mb-kbroughton:/21ct-ansible + (develop)] /usr/bin/python

Python 2.7.5 (default, Aug 25 2013, 00:04:04) 

[GCC 4.2.1 Compatible Apple LLVM 5.0 (clang-500.0.68)] on darwin

Type "help", "copyright", "credits" or "license" for more information.

>>> import httplib2

>>>

The play is run against localhost (my mac) but even the 3 controller openstack nodes have httplib2 installed (though in dist-packages not site-packages because it is ubuntu).

any ideas?

Do you have 'localhost' defined in your inventory?  If so, have you specified ansible_python_interpreter=/usr/local/bin/python along with it in your inventory?

You do mention that /usr/bin/python has access to httplib2, but that could be due to something such as setting PYTHONPATH somewhere that would allow /usr/bin/python to load httplib2 that it wouldn't otherwise have access to, and as a result ansible is running without access to PYTHONPATH maybe...

The code that determines if you have httplib2 is somewhat simple:

HAS_HTTPLIB2 = True

try:

    import httplib2

except ImportError:

    HAS_HTTPLIB2 = False

And later if HAS_HTTPLIB2 is False, it fails with the message you are seeing.

Perhaps try running:

/usr/bin/python -c "import httplib2; print httplib2.__file__"

/usr/local/bin/python -c "import httplib2; print httplib2.__file__"

As well as looking at:

echo $PYTHONPATH

httplib2 is getting picked up from the same place for either python install.

[kbroughton@mb-kbroughton:Contents/MacOS] /usr/bin/python -c "import httplib2; print httplib2.__file__"

/usr/local/lib/python2.7/site-packages/httplib2/__init__.pyc

[kbroughton@mb-kbroughton:Contents/MacOS] /usr/local/bin/python -c "import httplib2; print httplib2.__file__"

/usr/local/lib/python2.7/site-packages/httplib2/__init__.pyc

PYTHONPATH is pointing there

[kbroughton@mb-kbroughton:Contents/MacOS] echo $PYTHONPATH 

/usr/local/lib/python2.7/site-packages:/Users/kbroughton/vcp/git/mentat/ansible/lib:

But i'm not sure how to force pip to install it to the location that ansible has access to.

[kbroughton@mb-kbroughton:Contents/MacOS] export PYTHONPATH=''

[kbroughton@mb-kbroughton:Contents/MacOS] echo $PYTHONPATH 

[kbroughton@mb-kbroughton:Contents/MacOS] pip install httplib2

Requirement already satisfied (use --upgrade to upgrade): httplib2 in /usr/local/lib/python2.7/site-packages

Cleaning up...

[kbroughton@mb-kbroughton:Contents/MacOS] 

I suppose that pip belongs to the homebrew installed python, and i don't have pip installed for /usr/bin/python.

Setting ansible_python_interpreter=/usr/local/bin/python in the hosts file fixes the problem.

I've often found that using python from homebrew causes more problems than it solves.

You can probably do something like:

sudo PYTHONPATH="" /usr/bin/easy_install httplib2

On Mac, usually one of the first things I do is:

sudo /usr/bin/easy_install pip

Unfortunately that will try to squash pip provided by homebrew installed python as they both use /usr/local/bin/pip as their destination.

If you want to use python from homebrew, then your inventory modification is probably the right change to make.

Either that , or don't target localhost explicitly, remove localhost from your inventory and use local_action or delegate_to: localhost, which does some magic (implicit localhost) and uses the python binary used to invoke ansible as ansible_python_interpreter.
