我目前面临将 tinyDB python 包导入 python 的问题。

这些是我在 raspbian 中安装 tinyDB 的步骤。1.运行命令：sudo pip3 install tinydb

输出显示：要求已经满足（使用 --upgrade 升级）：/usr/local/lib/python3.4/dist-packages 中的 tinydb

这意味着 tinydb 包已成功安装，并且 setup.py 已安装。

这是我在 python 中导入 tinydb 的代码。

代码：

    from tinydb import TinyDB, Query

    db = TinyDB('/home/pi/Desktop/book/book.json')
    table = db.table('name')
    table.insert({'value': True})
    table.all()
    [{'value': True}]

但是，将 tinydb 导入 python 时，会出现此错误： ImportError: cannot import name 'TinyDB'

更新：

修复了模块未找到错误但现在有另一个错误。错误：

Traceback (most recent call last):
