解決pyinstaller打包后運行，出現ModuleNotFoundError: No module named 'pywt._extensions._cwt'

終於把打包問題解決了，Python打包方法——Pyinstaller CentOS下踩坑記錄

美滋滋，趕緊發給同事試一下

居然報錯

Traceback (most recent call last):

莫非環境原因？本地試一下，同樣的錯誤。。。

 

搜到了這個https://blog.csdn.net/zyc121561/article/details/79562935

需要添加hiddenimport

 

查一下官方文檔

--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，直接在打包時候引入參數就可以

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

 

放到服務器上試一下，又報錯

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

理論上，應該使用--add-binary，可是實際測下來--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
