在MAC上使用PY2APP打包keyring模块时出错

Question

我正在用python制作一个需要存储密钥的应用程序。我使用keyring模块来存储密钥。我使用的是python-2.7和OSX10.8.5以及keyring 3.2( easy_install keyring)。代码在eclipse上运行良好，但当我使用py2app将代码转换为应用程序时，它显示了MYAPP错误打开控制台终止错误

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

在通过py2app创建dist时，我在输入"python setup.py py2app“时包含了终端响应碎片。

Answer 1

我不确定你是否解决过这个问题，但我在我的Mac上遇到了类似的问题(使用pythonv2.7.6和py2app v0.9)：脚本从命令行(即python scriptname.py)运行得很好，但当我使用py2app将其转换为.app时，它失败了。

控制台消息使我得出结论，py2app还不够聪明，不能包含keyring.backends模块中的子模块。因此，我显式地将所有内容都导入到那里，它终于起作用了：

import keyring.backends.file
import keyring.backends.Gnome
import keyring.backends.Google
import keyring.backends.kwallet
import keyring.backends.multi
import keyring.backends.OS_X
import keyring.backends.pyfs
import keyring.backends.SecretService
import keyring.backends.Windows
import keyring

我希望这对你有帮助！

我没有可能在本地尝试，以下是我最好的猜测：

尝试导入应用程序中实际需要的所有代码，包括在“正常”执行过程中不会发生的异常

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

在运行时，您可能还需要一些其他包，以进行检查，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'])

您可以看到有多少模块是由于import keyring而引入的，但也有一些模块是由于keyring.set_password(...)而引入的。

现在，对于py2app，大部分操作应该是自动完成的，但是可以忽略一些运行时依赖项。

这背后的原因是，py2app在决定包含哪些模块时会做一些棘手的事情。假设keyring.set_password()实际上并没有在这个阶段运行。事实上，如果是这样的话，set_password肯定会有副作用，你会期望py2app打包一个普通的或修改过的模块吗？

Answer 3

在setup.py中包含packages='keyring.backends'，以包含所有密钥环的包。
