python - Heroku 应用程序无法运行，产生两个错误：错误 7 和错误 98

Question

我正在尝试仅使用 Plotly Go 情节来运行 Heroku 应用程序的第一遍。我可以在本地运行它，但是当我尝试在 Heroku 上运行它时出现此错误。

我的 Python 文件 (app.py) 如下所示：

import plotly.graph_objects as go
import numpy as np
import matplotlib.pyplot as plt
import pandas as pd
import plotly.graph_objects as goimport dash
import dash_core_components as dcc
import dash_html_components as html

# Read data from excel and create figure.

app = dash.Dash()
server = app.server
app.layout = html.Div([
    dcc.Graph(figure=fig1)
])

app.run_server(debug=True, use_reloader=False)

我的 Procfile 看起来像这样：

web: gunicorn app:server

我的Requirements.txt 看起来是这样的：

我用谷歌搜索，错误 98，地址已在使用中并尝试了这个：

但是在我在 CMD 上运行“neststat”命令后什么也没发生。

我试过这个：

但它说，“ps 不被识别为内部或外部命令”。我有 Windows 10。

任何帮助将不胜感激。
