AttributeError: 'module' object has no attribute 'Consumer'

How to Reproduce

While doing a POST operation on /admin/spamfilter/external, Trac issued an internal error.

I added public / private keys for Mollom and pressed Apply changes.

Running the latest version of TracSpamFilter, 1.0.6 r14092.

>>> import oauth2
>>> oauth2.VERSION
'0.7.0'

[Ryan J Ollos]

I had oauthlib-0.7.2 and python-oauth2-0.7.0 also installed. I removed those with pip uninstall.

>>> import oauth2
>>> dir(oauth2)
['Client', 'Consumer', 'Error', 'HTTP_METHOD', 'MissingSignature', 'OAUTH_VERSION', 'Request', 'SIGNATURE_METHOD', 'Server', 'SignatureMethod', 'SignatureMethod_HMAC_SHA1', 'SignatureMethod_PLAINTEXT', 'Token', '__builtins__', '__doc__', '__file__', '__name__', '__package__', '__path__', '__version__', '_version', 'base64', 'binascii', 'build_authenticate_header', 'build_xoauth_string', 'escape', 'generate_nonce', 'generate_timestamp', 'generate_verifier', 'hmac', 'httplib2', 'parse_qs', 'random', 'setter', 'sha', 'sha1', 'time', 'to_unicode', 'to_unicode_if_string', 'to_unicode_optional_iterator', 'to_utf8', 'to_utf8_if_string', 'to_utf8_optional_iterator', 'urllib', 'urlparse']
>>> oauth2.__version__
LooseVersion ('1.5.211')

Now I can successfully add the Mollom keys.
