在MAC OSX上使用PY2APP打包密钥环模块时出错

Question

我在python中创建一个需要存储密钥的应用程序.我使用密钥环模块来存储密钥.我使用python-2.7和osx 10.8.5与密钥环3.2(easy_install密钥环).代码在eclipse上正常运行,但是当我使用py2app将代码转换为应用程序时,它显示错误的MYAPP错误打开控制台终止

import keyring
keyring.set_password("title","section","keys")
res= keyring.get_password("title","section")

我在键入"python setup.py py2app"时包含终端响应废料,同时通过py2app制作dist

我无法在本地尝试此操作，这是我的最佳猜测：

尝试导入应用程序中实际需要的所有位，包括“正常”执行期间不会发生的异常

import keyring
import keyring.set_password as _unused_1
import keyring.backend
import keyring.backend.PasswordSetError as _unused_2

您可能还需要在运行时使用其他一些包，要检查它，请执行以下操作：

$ python2.7
Python 2.7.5 (default, Sep  6 2013, 09:55:21) 
[GCC 4.8.1 20130725 (prerelease)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> before = sys.modules.keys()
>>> import keyring
>>> middle = sys.modules.keys()
>>> keyring.set_password("a", "b", "c")
Please set a password for your new keyring
Password: 
Password (again): 
Please input your password for the keyring
Password: 
>>> after = sys.modules.keys()
#
# now the interesting bits
#
>>> set(after).difference(set(middle))
set(['struct', 'crypt', 'base64', 'binascii', 'keyring.crypt', 'encodings.base64', 'encodings.base64_codec', '_struct'])
#
# and this
#
>>> set(middle).difference(set(before))
set(['cStringIO', 'heapq', 'logging.threading', 'sre_compile', '_collections', 'logging.cStringIO', '_sre', 'getpass', 'atexit', 'keyring.backend', 'logging.os', 'operator', 'Crypto.Cipher.AES', 'logging.traceback', 'keyring.os', '_heapq', 'logging.time', 'keyring.ConfigParser', 'logging.weakref', 're', 'keyring.getpass', 'sre_constants', 'imp', 'logging.codecs', 'collections', 'logging.thread', 'keyring.imp', 'keyring.logging', 'keyring.keyring', 'string', 'keyring.util.re', 'time', 'Crypto', 'termios', 'keyring.util.escape', 'logging', 'logging.atexit', 'keyring.util', 'logging.sys', 'keyring.abc', 'Crypto.Cipher', 'ConfigParser', 'keyring.util.string', 'keyring.getpassbackend', 'keyword', 'thread', 'strop', 'traceback', 'keyring', 'weakref', 'threading', 'itertools', 'keyring.Crypto', 'keyring.sys', 'sre_parse', 'logging.warnings', 'keyring.core'])

您会看到有多少模块是由于 引入的import keyring，而且还有更多模块是由于 引入的keyring.set_password(...)。

现在，大部分应该是自动的py2app，但一些运行时依赖项可能会被忽略。

这背后的原因是py2app当它决定包含哪些模块时会做一些棘手的事情。假装keyring.set_password()该阶段实际上并未运行。事实上，如果它确实有并且set_password必须有副作用，您会期望py2app打包一个普通的或修改的模块吗？
