Nuitka: Issue about "Can't perform this operation for unregistered loader type"

My script runs correctly and output what I wanted. But I packed my python scripts to exe file, it raised “Can’t perform this operation for unregistered loader type” when I run the exe file.

my nuitka command: python -m nuitka --mingw64 --standalone --show-progress --recurse-all --enable-plugin=numpy --include-package=openpyxl --include-package=markupsafe --include-package=jinja2 --follow-imports --output-dir=exeFiles mytest.py

my envirionmnet: Windows 7 I installed all the packages(nuitka, jinja2,…) by pip

python -m nuitka --version 0.6.8.4 Python: 3.6.8 (tags/v3.6.8:3c6b436a57, Dec 23 2018, 23:31:17) [MSC v.1916 32 bit (Intel)] Executable: C:\Program Files (x86)\Python36-32\python.exe OS: Windows Arch: x86
