解决pyinstaller打包后运行，出现ModuleNotFoundError: No module named 'pywt._extensions._cwt'

终于把打包问题解决了，Python打包方法——Pyinstaller CentOS下踩坑记录

美滋滋，赶紧发给同事试一下

居然报错

莫非环境原因？本地试一下，同样的错误。。。

搜到了这个https://blog.csdn.net/zyc121561/article/details/79562935

需要添加hiddenimport

查一下官方文档

--hidden-import MODULENAME, --hiddenimport MODULENAME

Name an import not visible in the code of the script(s). This option can be used multiple times.

不需要修改package中的配置，直接在打包时候引入参数就可以

pyinstaller -F --hidden-import=pywt --hidden-import=pywt._extensions._cwt app.py

放到服务器上试一下，又报错

ImportError: libxcb.so.1: cannot open shared object file: No such file directory

理论上，应该使用--add-binary，可是实际测下来--add-data也可以

pyinstaller -F --add-binary '/usr/lib64/libxcb.so.1:.' --hidden-import=pywt --hidden-import=pywt._extensions._cwt app.py
pyinstaller -F --add-data /usr/lib64/libxcb.so.1:. --hidden-import=pywt --hidden-import=pywt._extensions._cwt app.py

　　

搞定
