我只是第一次将我的应用程序推送到 heroku,但是当我访问该页面时不断收到“应用程序错误”。我对 heroku 不熟悉,似乎在帮助/开发中心链接中找不到任何参考。
去heroku日志我得到这个:

我不太确定这些都是什么意思。但我假设它与gunicorn连接有关?有人可以帮助指出这个问题以及我该如何解决这个问题?
注意:没有 ImportError: No module named xxxxx --> xxxxx 是我的应用程序的名称。这也是我在 procfile 中使用的(例如 xxxxx:app)。这是问题吗?
编辑:这是一个 Flask 应用程序,所以这是我拥有的当前结构
-static
--css
--img
--js
-templates
--index.html
--layout.html
-.gitignore
-Procfile
-requirements.txt
-app.py
我的档案:
web: gunicorn app:app
Edit2:这是我的 app.py 文件
from flask import Flask, render_template
app = Flask(__name__)
@app.route('/')
def main():
return render_template("index.html")
@app.route('/projects')
def projects():
...
