解决pyinstaller 打包后运行exe程序出现的"ModuleNotFindError"

作者博客地址：http://www.yooongchun.cn/

在用pyinstaller打包python程序
pyinstaller版本为：3.3.1
python 版本：3.6.1
系统版本：Windows-10-10.0.16299-SP0

---

我的python程序名为：data_processing_gui.py
程序在python环境下正常运行。
打包使用的格式为：pyinstaller -F -p <导入的包路径> myprogram.py
完整打包命令为：

 pyinstaller -F -p C:UsersfanyuAnaconda3Lib;C:UsersfanyuAnaconda3Libsite-packages;C:UsersfanyuAnaconda3Libsite-packagesPyQt5Qtin;C:UsersfanyuAnaconda3Libsite-packagespydicom;C:UsersfanyuAnaconda3Libsite-packages
adiomics;C:UsersfanyuAnaconda3Libsite-packagespywt;C:UsersfanyuAnaconda3Libsite-packagespywt\_extensions;C:UsersfanyuAnaconda3Libsite-packages	ensorflow;C:UsersfanyuAnaconda3Libsite-packagesSimpleITK;C:UsersfanyuAnaconda3Libsite-packagesPIL;C:UsersfanyuAnaconda3Libsite-packagespandas;C:UsersfanyuAnaconda3Libsite-packages
rrd;C:UsersfanyuAnaconda3Libsite-packages
umpy -i C:UsersfanyuDesktopworkpackageimagedoctor.ico data_processing_gui.py
pause

打包过程无报错，打包完成后运行程序提示出错信息：

 Traceback (most recent call last):

ModuleNotFoundError: No module named 'pywt._extensions._cwt'

最后在Stackoverflow上发现了一个类似问题，最终解决了问题
解决方案是：

首先，使用pyinstaller 打包生成".spec" 文件

接下来，使用文本编辑器打开".spec"文件，在 hiddenimport=[] 部分添加缺少的module，我的程序中缺少的是 pywt 模块，因而添加：

hiddenimport=[
"pywt","pywt._extensions._cwt"]

然后使用pyinstaller 生成新的exe程序：

pyinstaller my.spec

最终，问题解决。
