错误“ImportError：无法从‘bson’导入名称‘_get_object_size’”

Question

运行以下文件时，我收到错误“ImportError：无法从 'bson' 导入名称 ' get_object_size' (C:\Users\Dell\AppData\Local\Programs\Python\Python310\lib\site-packages\bson_ init。 py）”

代码：`from Flask import Flask, request, jsonify fromflask_pymongo import PyMongo # from bson.objectid import ObjectId

app = Flask(__name__)
app.config['MONGO_URI'] = connectionstring
mongo = PyMongo(app)

# Create a new to-do item
@app.route('/api/todo', methods=['POST'])
def create_todo():
    # data = request.json

    # Create a new to-do item in the database
 new_todo = {
        # 'task': data['task'],
        # 'due_date': data['due_date'],
        # 'completed': False
        "task": "study",
        "date": 18,
        "completed": False
    }

 result = mongo.db.todos.insert_one(new_todo)
 print(result,"has been created")`

我正在使用 Flask 环境创建一个待办事项列表。

Answer 1

卸载 pymongo 和 bson 并仅安装 pymongo，pymongo 会自动安装 bson

pip uninstall pymongo

pip uninstall bson

pip install pymongo
