【问题描述】：
我正在尝试将多个 .json 合并到一个 json 文件中
代码：
import glob, json
read_files = glob.glob("*.json")
output_list = []
for f in read_files:
with open(f, "rb") as infile:
output_list.append(json.load(infile))
all_items = []
for json_file in output_list:
all_items += json_file['value']
textfile_merged = open('merged.json', 'w')
json.dump({ "value": all_items }, textfile_merged)
textfile_merged.close()
我收到以下错误
> Traceback (most recent call last): File "D:\JSON\merge.py", line 7,

其中一个文件不是有效的 JSON。
