Is this extension suitable for CKAN2.10.3 (new version)?

[hongjie123]

The version of ckan I am using is 2.10.3. After installing the ckanext cloudstorage extension, restarting ckan cannot run properly, and the error is as follows:

error1：
File "/usr/lib/ckan/default/src/ckanext-cloudstorage/ckanext/cloudstorage/storage.py", line 12, in
from pylons import config
ModuleNotFoundError: No module named 'pylons'

error4：

raise AttributeError(f"module '{name}' has no attribute '{name}'")
AttributeError: module 'ckan.plugins' has no attribute 'IRoutes'

How can I solve the above problem?
Is it because the version of ckan is incompatible with the version of cloudstorage?

CKAN == 2.10.3
Python == 3.8.10
