Question

with open(filepath) as filedata:
    decks = json.load(filedata)

我使用上面的代码尝试加载由Scrapy Spider创建的JSON文件。我最近重新使用刮刀来获取更新的JSON文件，并且当我尝试加载新文件时，格式应该相同但上面的行通过以下错误。（请注意，这不会附加到任何现有文件）。

    Traceback (most recent call last):
  File "/Users/tonysitu/Documents/workspace/Mtg/ArchetypeAnalysis/analyze/deck_stats.py", line 215, in launcher
    standard = constructFormat()
  File "/Users/tonysitu/Documents/workspace/Mtg/ArchetypeAnalysis/analyze/deck_stats.py", line 98, in constructFormat
    decks = json.load(deckData)
  File "/Users/tonysitu/anaconda3/lib/python3.4/json/__init__.py", line 268, in load
    parse_constant=parse_constant, object_pairs_hook=object_pairs_hook, **kw)
  File "/Users/tonysitu/anaconda3/lib/python3.4/json/__init__.py", line 318, in loads
    return _default_decoder.decode(s)
  File "/Users/tonysitu/anaconda3/lib/python3.4/json/decoder.py", line 346, in decode
    raise ValueError(errmsg("Extra data", s, end, len(s)))
ValueError: Extra data: line 120 column 835 - line 306 column 945 (char 99352 - 254693)

我已经使用网络上的各种应用程序验证了JSON文件，但没有一个引发错误。此外，所有词典都由一组[]括号括起来。我没有改变我的刮刀，数据格式似乎与我以前工作的JSON文件相同。我不确定导致错误的原因。我会很感激任何建议，但我想避免使用json.loads（）并逐行浏览文件。

Answer 1

解决了，错误是由于我的框架命名空间中的错误而不是实际的JSON文件。请参阅上面的评论。
