can not import finplot

[gitlong]

installed finplot 1.9.0, using python3.8, when compiling showed following error.

Traceback (most recent call last):
File "/Users/kevin/Desktop/Pandas/masterpandasfinance/chap5timeseriesstock.py", line 65, in
import finplot as fplt
File "/Users/kevin/Documents/pythonlearn/lib/python3.8/site-packages/finplot/init.py", line 2824, in
any(sanctioned in code.lower() for sanctioned in 'ru be'.split()):

any(sanctioned in code.lower() for sanctioned in 'ru be'.split()):
AttributeError: 'NoneType' object has no attribute 'lower'

Then I installed lower version of finplot 1.8.3 and 1.7 showing other errors:
Traceback (most recent call last):
File "/Users/kevin/Desktop/Pandas/masterpandasfinance/chap5timeseriesstock.py", line 65, in

TypeError: call() missing 1 required positional argument: 'value'

Please help me.

Ah, this is a bug which happens when the python environment can't detect a default locale. I put a fix in commit dbf1cad. To patch your code do this:

git clone https://github.com/highfestiva/finplot.git
cp finplot/finplot/__init__.py /Users/kevin/Documents/pythonlearn/lib/python3.8/site-packages/finplot/

The next version will contain this fix. GL!
