Hi,

I’m trying to debug Ansible modules.  
I usually do this, for example.  
(args.json is parameters file)

`  
python ./ansible/lib/ansible/modules/source\_control/subversion.py ./args.json

`

I tried to debug for “yum” module.  
But, this error occurred.  
What is error for?

`  
python ./ansible/lib/ansible/modules/packaging/os/yum.py ./args.json

`

`  
Traceback (most recent call last):

File “./ansible/lib/ansible/modules/packaging/os/yum.py”, line 1667, in   
main()  
File “./ansible/lib/ansible/modules/packaging/os/yum.py”, line 1663, in main  
module\_implementation.run()  
File “./ansible/lib/ansible/modules/packaging/os/yum.py”, line 1601, in run  
my = self.yum\_base()  
File “./ansible/lib/ansible/modules/packaging/os/yum.py”, line 458, in yum\_base  
my = yum.YumBase()  
AttributeError: ‘module’ object has no attribute ‘YumBase’  
`

Ansible version is

`

# ansible --version

ansible 2.10.0.dev0  
config file = None  
configured module search path = [u’/root/.ansible/plugins/modules’, u’/usr/share/ansible/plugins/modules’]  
ansible python module location = /root/ansible/lib/ansible
