AttributeError: module 'pandas_datareader.data' has no attribute 'get_data_google'`

When importing from yahoo using yfinance or datareader, the DataFrame's index tag is named 'Date'. The problem seems to point to what should be named 'date'.
I have made the modification of this name in the DataFrame and the problem continues. How can I fix this problem?. Thanks in advanced.
