Python: 使用pyinstaller打包exe时报错JSONDecodeError: Expecting value: line 1 column 1 (char 0)

环境win7,python3.6,pyinstaller3.5 and 3.4,在用pyinstaller打包的时候会报错。

_raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)
_

已通过Python3.5解决
