index_name isn't usable in currency_hist_df about akshare

[albertandking]

TypeError Traceback (most recent call last)
in
1 import akshare as ak
----> 2 currency_hist_df = ak.currency_hist(index_name="usd/jpy", start_date="2005/01/01", end_date="2020/01/17")
3 print(currency_hist_df)

TypeError: currency_hist() got an unexpected keyword argument 'index_name'

I already upgraded akshare. Without index_name the code runs well.

I have checked the interface, it's work well.
Please update to lastest version.

I am so sorry for that, I had fixed the example error in documentation!
