为什么得到“ JSONDecodeError：期望值：第1行第1列（字符0）”？

Question

JSONDecodeError：预期值：第1行第1列（字符0）

我对Python比较陌生，不知道为什么会这样。我的数据集是一个JSON文件，其中包含有关YELP评论的信息

我的代码：

import json

import pandas as pd


readLimit = 1e3


def loadJSON(fileLocation):
    data = []
    with open(fileLocation) as file:
        for index, line in enumerate(file):
            if index > 1e3:
                break
            data.append(json.loads(line))
    return pd.DataFrame(data)

data = loadJSON("yelp_dataset.json")
print(data.info())

弹出的错误消息：

     16     return pd.DataFrame(data)
