Flask==2.0.1
Flask_PyMongo==2.3.0
numpy==1.21.2
pandas==1.3.2
pymongo==3.12.0

最后是我的 app.py 代码

from flask import Flask, render_template
from logging import debug
from flask_pymongo import PyMongo
from werkzeug.utils import append_slash_redirect, redirect
from script import api_call
import easygui

app = Flask(__name__)


@app.route('/')
def home():
    return render_template('index.html')

@app.route("/script")
def script():
    api_call()
    easygui.msgbox("Database Updated Successfully!", "Success")
    return redirect("/")

@app.route("/heatmap")
def heatmap():
    return render_template('heatmap.html')
       

if __name__ == '__main__':
    app.run()

【问题讨论】：

这个问题记录在另一个包中描述了问题在于tkinter——由easygui调用——在Heroku上不可用：github.com/pyppeteer/pyppeteer/issues/215我不知道任何允许您创建 GUI 的 Web 服务，除非您以某种方式登录到远程系统并以这种方式查看它？
好的，我正在使用easygui在数据库更新时显示一条消息。我会尝试删除它并重新部署。
现在看来 Heroku 很难找到我的渲染模板。
您可能想要编辑问题以发布当前日志输出。 render_template 的导入看起来没问题。

标签： heroku heroku-cli

【解决方案1】：

这是 easygui 和尝试导入 tkinter 的问题。之后渲染模板无法正常工作。我很想重组文件，一切都很好。谢谢！
