使用py2exe打包时不包含密钥环模块

Question

我正在使用Windows上的python 2.7和keyring-3.2.1创建一个应用程序.在我的eclipse上的python代码中,我使用了

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

工作正常,因为我在密钥环中存储json响应.但是,当我使用py2exe将python代码转换为exe时,它会在制作dist时显示导入错误密钥环.请建议如何在py2exe中包含密钥环.

platform_.py代码是:

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():
    """
    Use freedesktop.org Base Dir Specfication to determine storage
    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代码是:

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():

    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)

您报告的问题是由于包含无效模块的环境,可能是由于一个版本的密钥环安装不正确而导致的.您需要确保已删除旧版密钥环的残余内容.特别是,请确保您的站点包中没有名为keyring\util\platform.*的文件.

但是,在这之后,您将遇到另一个问题.密钥环以编程方式加载其后端模块,因此py2exe不会检测它们.

要解决这个问题,您需要在py2exe选项中添加一个"包"声明,以明确包含该keyring.backends包.我setup.py使用Python 2.7 调用以下脚本将'app.py'(导入密钥环)转换为exe:

from distutils.core import setup
import py2exe

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

生成的app.exe将导入并调用密钥环.
