在为python Web应用程序运行apache服务器时导入错误

Question

我在linux服务器配置上做我的项目，在亚马逊轻轨上使用ubuntu。我安装了python2.7.5并安装了python 3我通过更改别名将其更改为python 3，因为我的应用程序在python3上。

我的wsgi服务器配置如下

#!/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'

我的配置文件如下

<VirtualHost *:80>
    ServerName 52.24.125.53
    ServerAdmin [email protected]
    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>

当我尝试通过IP地址访问时，它显示内部错误500

以下是错误日志

我已经在python3和python2.7.5包上安装了所有模块。但仍然显示导入错误。我认为它与wsgi的问题。我是新手，请帮助解决问题。

Answer 1

您需要在应用中检查模块名称

我认为您导入了模块名称“from flask import flask”。

（要么）

你需要安装烧瓶

pip install Flask
