python nginx.py -p 80 -k accepts无法获取值

[spritluo]

我执行python nginx.py -p 80 -k accepts返回结果为空
ERROR:
[2018-08-16 00:54:29] ERROR
Traceback (most recent call last):
File "nginx.py", line 186, in main

File "/usr/lib/python2.7/site-packages/qiueer/python/filecache.py", line 38, in get_val_from_json
resobj = str(alllines[1]).strip()

不知道问题出在哪里，能帮忙解答一下吗
