Question

我在这里遵循了一个教程：https://tinyfox.rocks/2019/03/18/Install-Python-Dash-App-on-an-Ubuntu-Server/来设置一个Web服务器，该服务器将把我在Dash中制作的图表暴露给外部用户（只有1个，并且被认为是dev，而不是生产版本），而Im则有问题。

错误是： ModuleNotFoundError：没有名为“ pandas”的模块，引用：http://192.168.1.55:8080/

位于虚拟目录中我的app.py中

/etc/apache2/sites-available/FlaskApp.conf

   ServerName 192.168.1.55
   ServerAdmin youremail@email.com
   WSGIScriptAlias / /var/www/FlaskApp/FlaskApp.wsgi

#!/usr/bin/python3.6

import sys
import logging
logging.basicConfig(stream=sys.stderr)
sys.path.insert(0, "/var/www/FlaskApp/deribit-charting/")

from app import app
application = app.server

冻结点显示：

pandas==0.25.0

和app.py文件开始如下：

import dash
import dash_core_components as dcc
import dash_html_components as html
import plotly.graph_objs as go

app = dash.Dash(name='app')
server = app.server

现在，app.py导入一个调用

的db.py文件。

import config
import pandas as pd
import datetime as dt
from sqlalchemy import and_
from sqlalchemy.orm import sessionmaker, Session
from sqlalchemy.ext.declarative import declarative_base
import sqlalchemy as db

我认为这才是真正的问题所在。这意味着我的应用程序的一部分实际上正在加载，但是找不到熊猫。我没有类似pipenv或docker的东西。该服务器是为此1个应用程序构建的。
