python 3.x - Pdfminer, can not read LTText after pyinstaller

Question

I make an app that can read PDF using pdfminer.

Application is OK when development.
After that, I package to .exe file using pyinstaller. But read result is not the same with it in development.
In detail, it can not read **LTText LTTextBoxHorizontal so I can not get extracted text.
Any one know about this issue, please help me.

Answer 1

Pyinstaller lib owner just answered me. It fixed by adding --additional-hooks-dir.

Please see here for detail.

Maybe they will fix in pyinstaller to support pdfminer also in next release.
