Nuitka: Failed to acquire lock Local

Question

I tried to use Nuitka to pack my python project.

I executed this command in my anaconda environment.

python -m nuitka --standalone --show-memory --show-progress --follow-imports --nofollow-import-to=util --output-dir=out --include-data-dir=mdf=mdf --windows-icon-from-ico=./blur.ico --enable-plugin=numpy,pyside2 blur_exe.py

It seems everything went well during PASS 1 and PASS 2 stage. But I ran into issue at last in the Backend C stage.

Nuitka-Scons:INFO: Backend C compiler: cl (cl 14.2).

I thought it might because some folder was opened. So I closed the related programs and tried again. But errors were still there.

Answer 1

Well, I restarted my laptop, and tried packing once again. The error is gone.
