Import error on running apache server for python web application

Question

I am doing my project on linux server configuration and using ubuntu on amazon lighsail. i was having python2.7.5 and python 3 installed i changed it to python 3 by changing alias as my application is on python3.

My wsgi server is configured as below

#!/usr/bin/python
import sys
import logging
logging.basicConfig(stream=sys.stderr)
sys.path.insert(0,"/var/www/FlaskApp/")

from FlaskApp import app as application
application.secret_key = 'Add your secret key'

My config file is as below

<VirtualHost *:80>
    ServerName 52.24.125.53
    ServerAdmin abc@gmail.com
    WSGIScriptAlias / /var/www/FlaskApp/flaskapp.wsgi
    <Directory /var/www/FlaskApp/FlaskApp/>
        Order allow,deny
        Allow from all
    </Directory>
    Alias /static /var/www/FlaskApp/FlaskApp/static
    <Directory /var/www/FlaskApp/FlaskApp/static/>
        Order allow,deny
        Allow from all
    </Directory>
    ErrorLog ${APACHE_LOG_DIR}/error.log
    LogLevel warn
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

As i try to access by ip address it shows internal error 500

Below is the error log

you need to check module name in your app

I think that you imported the module name "from flask import flask".

(or)

you need to install flask

pip install Flask
