Flask wsgi python Import Error: no module named catalog

Question

我一直在按照 DigitalOcean and Flask 的教程设置一个在 ubuntu amazon lightsail 上运行的 flask wsgi python 应用程序，但我收到以下错误：

错误

[Tue Jul 25 16:09:14.573839 2017] [wsgi:error] [pid 19081:tid 140056986322688] [remote 65.102.85.13:26759]     from catalog import app as application

这是我当前的文件结构

drwxr-xr-x  ..
drwxr-xr-x  catalog
drwxr-xr-x  catalog.egg-info

和

我的 python.wsgi 文件 导入系统

import logging
logging.basicConfig(stream=sys.stderr)
sys.path.insert(0, "/var/www/catalog")

from catalog import app as application
application.secret_key = 'super_secret_key'

我的/etc/apache2/sites-enabled/catalog.config

我的setup.py文件

from setuptools import setup

setup(
    name='catalog',
    packages=['catalog'],
    include_package_data=True,
    install_requires=[
        'flask',
    ],
)

我可以获得我的虚拟环境 运行，但是我的浏览器 IP 仍然出现 500 内部服务器错误。我不明白为什么找不到模块，发生了什么？

Answer 1

通过将主应用程序文件更改为 __init__.py
