my procfile:我的档案:
web: gunicorn app:server
and my requirements.txt和我的要求.txt
dash_core_components==1.5.1
dash==1.6.1
dash_html_components==1.0.2
pandas==0.25.2
plotly==4.2.1

and my app.py和我的 app.py
if __name__ == '__main__':
app.run_server(debug=True)
The app runs perfectly locally该应用程序在本地完美运行
Seems to be a weird error message, atleast to me because this is the structure of my project似乎是一个奇怪的错误信息,至少对我来说,因为这是我项目的结构
Procfile
app.json
app.py
dataset1
dataset2
requirements.txt
I'm not sure why its failing to find the app application when its right there我不知道为什么它就在那里时找不到应用程序
NOTE: I don't have a folder named app and deleted app.json注意:我没有名为 app 的文件夹并删除了 app.json
我通过将此行添加到我的 app.py 解决了这个问题
server = app.server
