我的代码：

import datetime
from flask import Flask, render_template, request
from pymongo import MongoClient

app = Flask(__name__)
client = MongoClient(<connectionlink>)
app.db = client.blog

@app.route("/", methods=["GET", "POST"])
def index():
    if request.method == "POST":
        entry_content = request.form.get("content")
        formatted_date = datetime.datetime.today().strftime("%d-%m-%Y")
        app.db.entries.insert_one({"content":entry_content, "date":formatted_date})
        
    entries_with_date = [
        (
            entry["content"],
            entry["date"],
            datetime.datetime.strptime(entry["date"], "%d-%m-%Y").strftime("%b %d")
        )
        for entry in app.db.entries.find({})
    ]
    return render_template("index.html", entries=entries_with_date)

错误：

数据库和应用程序似乎都工作正常，但当我将flask debug设置为1并运行应用程序时，我得到了这个错误。从我在traceback上读到的内容来看，似乎是py-env问题，但我真的不知道该怎么办。
