pandas DataReader error on all data sources
#1
I have previously used the DataReader in pandas with various data sources.

Now Google and Yahoo are more or less deprecated, however I can't get data from any source.

The error I get:

NotImplementedError: data_source='morningstar' is not implemented 
Here it's 'morningstar', but I have tried others, ie. 'fred', 'google','quandl' etc.

Anyone who has problems? According to the pandas documentation this should be up running and even with new sources compatible.


oops mistake, shouldn't have been posted to homework.

Can I delete or move the post, or do we need an admin here?

Thanks a lot! I hadn't thought about checking my version of pandas-datareader and sure enough it was 0.2 or so.

Installing with pip directly didn't upgrade it for me. Though uninstalling and reinstalling worked for me. If anyone else has trouble I just did:

pip uninstall pandas-datareader
pip install pandas-datareader
I have it up running again now.
