Twitter API を使用してツイートを取得しています。これが私のコードです。エラーが発生しました (「JSON オブジェクトをデコードできませんでした」)。

import json
import urllib
def main():
    f1 = open('tweet-stream.json')
    count = 0
    for line in f1:
        d = json.loads(line)
        lang =  d['user']['lang']
        status_count = d['user']['statuses_count']
        print 'Language: ' + lang + 'Status Count' + str(status_count)

if __name__ == "__main__":
    main()

これは端末に着いているワット・イムです

Traceback (most recent call last):
  File "parseJSON.py", line 14, in <module>
    main()
  File "parseJSON.py", line 8, in main
    d = json.loads(line)
  File "/usr/lib/python2.7/json/__init__.py", line 326, in loads
    return _default_decoder.decode(s)
  File "/usr/lib/python2.7/json/decoder.py", line 360, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "/usr/lib/python2.7/json/decoder.py", line 378, in raw_decode
    raise ValueError("No JSON object could be decoded")
ValueError: No JSON object could be decoded

これは、JSON ファイルに保存されたツイートの 1 つです。
