pywt`_ctw`模块上的pyinstaller ImportError

Question

使用Pyinstaller _cwt编译程序时，Pywt未正确导入模块。我验证了_cwt.py它存在于我的pywt根目录中（在路径上的站点包中）并且_cwt.pyd在pywt\_extensions目录中。我可以从Python成功导入pywt。下面是一个最小（非）工作示例，用于说明ImportError回溯。

程序 pywt_test.py

# -*- coding: utf-8 -*-
try:
    import sys, traceback
    import pywt
    print pywt.__version__
except ImportError:
    type_, value_, traceback_ = sys.exc_info()
    e_msg = traceback.format_exception(type_, value_, traceback_)
    with open('pywt_error_log.txt','w') as f:
        f.write(''.join(e_msg))

pyinstaller规范文件 pywt_test.spec

 # -*- mode: python -*-

 block_cipher = None


 a = Analysis(['pywt_test.py'],
         pathex=['C:\\Users\\user', 'C:\\Users\\user'],
         binaries=[],
         datas=[],
         hiddenimports=[],
         hookspath=[],
         runtime_hooks=[],
         excludes=[],
         win_no_prefer_redirects=False,
         win_private_assemblies=False,
         cipher=block_cipher)
 pyz = PYZ(a.pure, a.zipped_data,
         cipher=block_cipher)
 exe = EXE(pyz,
      a.scripts,
      a.binaries,
      a.zipfiles,
      a.datas,
      name='pywt_test',
      debug=False,
      strip=False,
      upx=False,
      console=True)

pyinstall编译命令：pyinstaller pywt_test.spec。

命令运行： pywt_test.exe

内容pywt_error_log.txt：

Traceback (most recent call last):
  File "pywt_test.py", line 10, in <module>
  File "c:\users\user\appdata\local\temp\pip-build-3zvqo7\pyinstaller\PyInstaller\loader\pyimod03_importers.py", line 389, in load_module
  File "site-packages\pywt\__init__.py", line 16, in <module>

  File "pywt\_extensions\_pywt.pyx", line 1, in init pywt._extensions._pywt (pywt\_extensions\_pywt.c:32588)
 ImportError: No module named _cwt

我尝试将其添加_cwt到pathex，hiddenimports等中。没有一个可以更改错误。

如何获得_cwtPyinstaller以及整个pywt软件包？

版本，以供参考：

• y：0.5.1
• Pyinstaller的：3.2.1
• Python：Windows 7 64位（Anaconda）上的2.7.12 64位

只需将其添加到隐藏的导入中即可：

 ...
 hiddenimports=['pywt._extensions._cwt'],
 ...
