peewee.OperationalError: no such function: json

Question

Python版本：3.8.3

Peewee 版本：3.13.3

我想创建一个包含 JSONField 的对象，

db = SqliteExtDatabase('../db.sqlite', pragmas=(('journal_mode', 'wal'), ('foreign_keys', 1)))

class Msg(BaseModel):
    id = AutoField()
    detail = JSONField()

def insert_msg(detail: dict):
    msg = Msg.create(detail=detail)
    msg.save()

但是当我调用方法 insert_msg({"name":"abc"}) 时，出现错误

您需要安装 sqlite json1 扩展。以下是一些可能有帮助的链接：
