 I only write the scripts for building standalone executable files on windows, [Nuitka script](scripts/nuitka_build.bat) and [pyinstaller script](scripts/pyinstaller_build.bat).
 
-The version after 0.5.4a doesn't support Nuitka build since 0.5.4a import google.cloud package and it contains `pkg_resources.get_distribution` which is not supported by Nuitka due to this [Nuitka issue #146](https://github.com/Nuitka/Nuitka/issues/146). You can manually remove the codes include the google.cloud package and build it. I will consider remove the codes to support Nuitka build in the future version.
