使用ModuleNotFoundError进行PyGObject hello world的py2app回溯

Question

我试图使用py2app将一个测试程序(一个"hello world")捆绑成一个macOS应用程序。

我得到的错误是：

/Applications/hello.app/Contents/MacOS/hello
Traceback (most recent call last):
  File "/Applications/hello.app/Contents/Resources/__boot__.py", line 101, in <module>
    _run()
  File "/Applications/hello.app/Contents/Resources/__boot__.py", line 84, in _run
    exec(compile(source, path, "exec"), globals(), globals())
  File "/Applications/hello.app/Contents/Resources/hello.py", line 5, in <module>
    import gi
  File "<frozen zipimport>", line 259, in load_module
  File "gi/__init__.pyc", line 40, in <module>
  File "<frozen zipimport>", line 259, in load_module
  File "gi/_gi.pyc", line 14, in <module>
  File "gi/_gi.pyc", line 10, in __load
  File "imp.pyc", line 342, in load_dynamic
ModuleNotFoundError: No module named 'gi._error'
2021-06-08 10:19:34.605 hello[41423:3966514] hello Error
make: *** [go] Error 255

该程序在py2app之外运行得很好，它是：

$ cat hello.py
cmd output started 2021 Tue Jun 08 10:20:44 AM PDT
#!/usr/bin/env python3

"""Just say hi."""

import gi
gi.require_version("Gtk", "3.0")
from gi.repository import Gtk  # noqa

window = Gtk.Window(title="Title")
button = Gtk.Button(label='Hello World!')
button.show()
button.connect("clicked", Gtk.main_quit)
window.add(button)
window.show()
window.connect("destroy", Gtk.main_quit)
Gtk.main()

我的setup.py看起来像这样：

$ cat setup.py
cmd output started 2021 Tue Jun 08 10:21:27 AM PDT
"""
This is a setup.py script derived from https://stackoverflow.com/questions/5608080/how-to-specify-py2app-icon .

Usage:
    python3 setup.py py2app
"""

from setuptools import setup

app = ['hello.py']
options = {
    'iconfile': 'icon/hello.png',
}

setup(
    app=app,
    options={'py2app': options},
    setup_requires=['py2app'],
)

下面是我一直在使用的Makefile，其中包括创建图标文件：

$ cat Makefile
cmd output started 2021 Tue Jun 08 10:22:25 AM PDT
go: clean
    ./hello.py
    pbmtext 'hello!' | pnmtopng > icon/hello.png
    python3 setup.py py2app
    (cd dist && tar cflS - hello.app) | (cd /Applications && tar xvfp -)
    /Applications/hello.app/Contents/MacOS/hello

clean:
    rm -rf build dist
    rm -f icon/hello.png

我在macOS Big Sur (11.4)上使用自制的Python3.9.5和py2app==0.24。py2app是用pip安装的。

我怀疑这种情况需要一个“配方”，但我在py2app文档中没有看到用于PyGObject的配方。

我已经在谷歌上搜索了几个小时了，但没有任何收获。

有人有什么建议吗？

谢谢!

奇怪的是，重启操作系统有帮助，还有已经尝试过的：

options = {
    'iconfile': 'icon/hello.png',
    'packages': ['gi'],
}

现在我得到了一个不同的错误--一个段错误。但我想我可能扫清了一个障碍。
