keyring module is not included while packaging with py2exe

问题

I am making an app using python 2.7 on windows and keyring-3.2.1 . In my python code on eclipse, I used

import keyring
keyring.set_password("service","jsonkey",json_res)
json_res= keyring.get_password("service","jsonkey")

is working fine as I am storing json response in keyring. But, when I converted python code into exe by using py2exe, it shows import error keyring while making dist. Please suggest how to include keyring in py2exe.

Traceback (most recent call last):
  File "APP.py", line 8, in <module>

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

platform_.py code is :

from __future__ import absolute_import

import os
import platform

def _data_root_Windows():
    try:
        root = os.environ['LOCALAPPDATA']
    except KeyError:
        # Windows XP
        root = os.path.join(os.environ['USERPROFILE'], 'Local Settings')
    return os.path.join(root, 'Python Keyring')

def _data_root_Linux():
    """

    location.
    """
    fallback = os.path.expanduser('~/.local/share')
    root = os.environ.get('XDG_DATA_HOME', None) or fallback
    return os.path.join(root, 'python_keyring')

# by default, use Unix convention
data_root = globals().get('_data_root_' + platform.system(), _data_root_Linux)

platform.py code is:

import os
import sys

# While we support Python 2.4, use a convoluted technique to import
#  platform from the stdlib.
# With Python 2.5 or later, just do "from __future__ import absolute_import"
#  and "import platform"
exec('__import__("platform", globals=dict())')
platform = sys.modules['platform']

def _data_root_Windows():
    try:
        root = os.environ['LOCALAPPDATA']
    except KeyError:
        # Windows XP
        root = os.path.join(os.environ['USERPROFILE'], 'Local Settings')
    return os.path.join(root, 'Python Keyring')

def _data_root_Linux():

回答1:

The issue you're reporting is due to an environment that contains invalid modules, perhaps from an improper installation of one version of keyring over another. You will want to ensure that you've removed remnants of the older version of keyring. In particular, make sure there's no file called keyring\util\platform.* in your site-packages.

After doing that, however, you'll encounter another problem. Keyring loads its backend modules programmatically, so py2exe won't detect them.

To work around that, you'll want to add a 'packages' declaration to your py2exe options to specifically include the keyring.backends package. I invoked the following setup.py script with Python 2.7 to convert 'app.py' (which imports keyring) to an exe:

from distutils.core import setup
import py2exe

setup(
    console=['app.py'],
    options=dict(py2exe=dict(
        packages='keyring.backends',
    )),
)

The resulting app.exe will import and invoke keyring.
