false positive on pkg_resources.get_distribution

[powersj]

Steps to reproduce

The following Python code

from pkg_resources import get_distribution
print get_distribution('requests').version
print dir(get_distribution('requests'))

Produces the following output:

2.13.0
['EQEQ', 'PKG_INFO', '__class__', '__delattr__', '__dict__', '__doc__', '__eq__', '__format__', '__ge__', '__getattr__', '__getattribute__', '__gt__', '__hash__', '__init__', '__le__', '__lt__', '__module__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', '__weakref__', '_compute_dependencies', '_dep_map', '_get_metadata', '_key', '_parsed_pkg_info', '_provider', '_reload_version', '_version', '_warn_legacy_version', 'activate', 'as_requirement', 'check_version_conflict', 'clone', 'egg_name', 'extras', 'from_filename', 'from_location', 'get_entry_info', 'get_entry_map', 'has_version', 'hashcmp', 'insert_on', 'key', 'load_entry_point', 'location', 'parsed_version', 'platform', 'precedence', 'project_name', 'py_version', 'requires', 'version']

Current behavior

Pylint however complains:

E:  2, 6: Instance of 'str' has no 'version' member (no-member)

This looks identical to #36 but I was not sure what I am doing differently.

Expected behavior

No error message

pylint --version output

$ pylint --version
No config file found, using default configuration
pylint 1.6.5,
astroid 1.4.9

Same root cause as in #490. BTW. I think that it may not yet be shipped in latest public release. Do you mind checking it with pylint and astroid from master branches?

[powersj]

@rogalski Looks like using the versions from source did resolve this. Here are the specific versions used:

$ pylint --version
No config file found, using default configuration
pylint 1.7.0,
astroid 1.5.0
Python 2.7.13 (default, Jan 19 2017, 14:48:08)
[GCC 6.3.0 20170118]

We'll try to release shortly the new version, so this should work soon!
