How to explicitly set carriage return when executing json.dump?

Question

My python script creates a json file. And I have to support this python file running on windows and linux. The problem is the rollback carriage return on windows and linux. When I run this code in windows, it outputs CRLF json. And it outputs LF json when I run this on linux.

So, how to explicitly set carriage return when doing json dump in python3.5? i couln

import json
fpath = "hoge.json"
data = {"AGE": 12, "HOGE": [{"GUA": 3}]}
with open(fpath, 'wt', encoding="utf-8") as outfile:
    json.dump(data, outfile, indent=4, sort_keys=True, ensure_ascii=False)
