pyinstaller 打包总是出现 pyads.structs 模块缺失的问题

我用 2.7.18 版本的 32 位 python 写了一个与 ads 进行通讯的程序，但是在使用 pyinstaller 打包后运行时总是出现：

Traceback (most recent call last):
File "connect.py",line 7,in <module>
File "Lib\site-packages\PyInstaller\loader\pyimod03_importers.py",line 395,in load_module
File "site-packages\pyads\__init__.py",line 8,in <module>
ImportError:No module named structs
[6236]Failed to execute script connect

的问题，下面是我打包使用的 spec 文件：

# -*- mode: python ; coding: utf-8 -*-

block_cipher = None


a = Analysis(['connect.py'],
pathex=['E:\\code_for_work\\working\\connect_software'],
binaries=[],
datas=[],
hiddenimports=[
'pynput.keyboard._win32',
'pynput.mouse._win32',
'pyads',
'pyads.structs',
'pyads.ads',
'pyads.connection',
'pyads.pyads_ex',
'pyads.constants',
'pyads.symbol',
'pyads.structs',
'six.moves',
'importlib.util'
],
hookspath=[],
runtime_hooks=[],
excludes=[],
win_no_prefer_redirects=False,
win_private_assemblies=False,
cipher=block_cipher,
noarchive=False)
pyz = PYZ(a.pure, a.zipped_data,
cipher=block_cipher)
exe = EXE(pyz,
a.scripts,
a.binaries,
a.zipfiles,
a.datas,
[],
name='connect',
debug=False,
bootloader_ignore_signals=False,
strip=False,
upx=True,
upx_exclude=[],
runtime_tmpdir=None,
cOnsole=True )

我在 hiddenimports 中放了 pyads.structs ，但没有用
warn 文件：

This file lists modules PyInstaller was not able to find. This does not
necessarily mean this module is required for running you program. Python and
Python 3rd-party packages include a lot of conditional or optional module. For
example the module 'ntpath' only exists on Windows, whereas the module
'posixpath' only exists on Posix systems.

Types if import:
* top-level: imported at the top-level - look at these first
* conditional: imported within an if-statement
* delayed: imported from within a function
* optional: imported within a try-except-statement

IMPORTANT: Do NOT post this list to the issue-tracker. Use it as a basis for
yourself tracking down the missing module. Thanks!
