我正在使用Twitter的流API（通过tweepy）来收集符合某些条件的推文，但是当我使用json.loads()来解析创建的jsonl文件时，我得到以下错误：
File "twitter_time_series.py", line 19, in <module>
tweet = json.loads(line)
File "C:\Program Files\Anaconda3\lib\json\__init__.py", line 319, in loads
return _default_decoder.decode(s)
File "C:\Program Files\Anaconda3\lib\json\decoder.py", line 339, in decode
obj, end = self.raw_decode(s, idx=_w(s, 0).end())
File "C:\Program Files\Anaconda3\lib\json\decoder.py", line 357, in raw_decode
raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 2 column 1 (char 1)
我无法确定为什么，与其他类型的jsonl文件一样（如获取推特时间线等），这不会发生。谁可以帮助我？谢谢！
我正在使用基本的流推文：
auth = get_twitter_auth()
twitter_stream = Stream(auth, CustomListener(query_fname))
twitter_stream.filter(track=['curiosity'], async=True)
并加载json：
fname = sys.argv[1]
with open(fname, "r") as f:
for line in f:
tweet = json.loads(line)
我使用python 3.5和tweepy版本3.3.0，这是json文件的一行：

在for循环中，您可以尝试：
tweet = json.loads(line.decode())
或删除for循环并尝试：
tweets = json.load(f)
写入文件时，在Listener类中，您可以尝试：
def on_data(self, data):
with open('filename.json', 'a', newline='\n') as f:
f.write(data)
我也在Windows机器上遇到过这个问题。这是因为Windows使用CR LF行结束而Linux使用LF。
如果您尝试阅读一条推文，我认为它不会出现错误，您可以在此处看到：
json.decoder.JSONDecodeError: Expecting value: line 2 column 1 (char 1)
这很可能是json python包中的错误，而不是TwitterAPI。
见：The modern way: use newline=''
更多在线结尾：On Wikipedia，一如既往。
我刚才遇到了同样的问题。
我尝试使用json分析器测试json字符串，发现有一些错误的格式。
例如，False应为“False”，None应为“None”。
我的意思是首先你应该检查json字符串的格式是否正确，一种方法是在专门转换json格式的网站上测试它。
希望答案对你有所帮助。
