问题
My goal is to utilize puppet to initialize an instance of errbot, as well as pre-configure plugins via a script.
I followed their user guide found here:
http://errbot.io/en/latest/user_guide/provisioning.html#reading-stored-values
However I keep getting this error : "rejected by strategy 'SpecificBackendLocator'"
Here is my output(I do have my log variable in my config.py set to DEBUG):
/opt/errbot$ /opt/errbot/bin/errbot --storage-get core

{}
What I have tried:
I have tried using both the 'shelf', and 'memory' storage types
I have run in both python2.7 and 3.4
I have searched through all errbot related questions on this forum, I have searched through the github repo, as well as googled the error I am getting.
I have not been able to find anything that helps me resolve the issue.
I am not sure is this is more of an issue with the errbot module, or if it is how it is being run in my python environment. Any push in the right direction would be appreciated.

So far so good, then I make sure to issue the following command with sudo:

So the --storage-get function is working as expected. However, when I try --storage-set/merge:

Storage does not appear to have been opened yet
I get this error "Storage does not appear to be open yet.
I found this link by googling the error:
http://errbot.io/en/latest/_modules/errbot/storage.html
but I am having trouble understanding what I need to change so that I can merge, or set config values.
回答1:
rejected by strategy 'SpecificBackendLocator' is a misleading warning from yapsy saying that a plugin is not what it is looking at the moment while looping over all the plugins, it is a normal behavior.
The entry you are getting for core is {}, empty. Simply your Errbot instance has not store anything yet there.
For example check out this session:

I did exactly what you did and it works for me.
Is there anything special in your config ?
