Install and enable the external add-on in centos aarch64

Hi,

I am trying to install and enable the add-on using api in the centos 7.6.1810 aarch64. The add-on can be installed into add-on folder and no error reported when enabling it. However, the status of the add-on just keep false. I tried enable and disable the internal add-on, and it works fine. May i know how to solve it, please?

This is the script i used to print out all add-on and enable my external add-on.

Running Blender with --debug --debug-python might give more info. If not perhaps look into the enable function in addon_utils.py and try to figure out where exactly it fails.
