python - 为 python Web 应用程序运行 apache 服务器时导入错误

Question

我正在 linux 服务器配置上做我的项目，并在 amazon lighsail 上使用 ubuntu。 我安装了 python2.7.5 和 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 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>

当我尝试通过 ip 地址访问时，它显示内部错误 500

错误日志如下

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 有问题。我是新手，请帮助解决问题。

Answer 1

您需要检查应用中的模块名称

我认为您导入了模块名称“from flask import flask”。

(或)

你需要安装flask

pip install Flask
