Python 在 json.dumps 报错

[{"found_year":found_year,"jg_type":jg_type,"area":area,"source_gw_link":source_gw_link},{"company_news":json.dumps(OrderedDict (sorted(company_news.items())),encoding="Utf-8",ensure_ascii=False)}, {"name":name,"sex":sex,"company":company,"position":position,"role" :role, "edu_experience":json.dumps(OrderedDict (sorted(edu_experience.items())),encoding="Utf-8",ensure_ascii=False),"work_experience": json.dumps(OrderedDict (sorted(work_experience.items())),encoding="Utf-8",ensure_ascii=False)}, {"lingyu":lingyu,"jiguan":jiguan,"lunci":lunci,"jieduan":jieduan,"jieshao":jieshao,"money_type":money_type,"touzianlie":json.dumps(OrderedDict (sorted(tzanli.items())),encoding="Utf-8",ensure_ascii=False)},{"person_news":json.dumps(OrderedDict(sorted(person_news.items())),encoding="Utf-8",ensure_ascii=False)}])
File "/usr/lib64/python3.4/json/__init__.py", line 237, in dumps
**kw).encode(obj)
TypeError: __init__() got an unexpected keyword argument 'encoding'

因为我在 json.dumps 插入数据的时候是 unicode 这样写 但是报错是这样的
