Question

我正在尝试使用此存储库（https://github.com/schirinos/nutrient-db）来解析USDA的营养数据库。但是，我无法克服一些问题

python3 Nutritiondb.py -e> Nutritions.py

上面的代码行抛出以下错误

traceback (most recent call last):

File "nutrientdb.py", line 355, in <module>

main()

File "nutrientdb.py", line 332, in main

nutrients.refresh(path + 'FOOD_DES.txt', 'food_des')

File "nutrientdb.py", line 278, in refresh

for line in f:

File "/Users/benyam/anaconda3/lib/python3.6/codecs.py", line 321, in 
decode

(result, consumed) = self._buffer_decode(data, self.errors, final)

UnicodeDecodeError: 'utf-8' codec can't decode byte 0x91 in position 
4009: invalid start byte

我已经使用python 2.7（原始文件的默认设置）创建了Nutritions.json，并尝试将文件加载到json中，并引发以下错误：

Traceback (most recent call last):

File "<stdin>", line 2, in <module>
File
File
"/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/
json/__init__.py", line 339, in loads

return _default_decoder.decode(s)

File "/Library/Frameworks/Python.framework/Versions/2.7/lib/
python2.7/json/decoder.py", line 364, in decode
obj, end = self.raw_decode(s, idx=_w(s, 0).end())

 File
 "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7
 /json/decoder.py", line 382, in raw_decode
 raise ValueError("No JSON object could be decoded")
 ValueError: No JSON object could be decoded

我现在的问题是，如何确定解析器内部导致此问题的代码行，即Nutritiondb.py？还有什么解决办法？
