Error: ImportError while deploying Flask app in wsgi file

Question

我不知道我到底错过了什么。这是我到目前为止所拥有的：

wsgi

/opt/tools/apps/scheduler/scheduler.wsgi

其内容

from scheduler import app as application

init.py

/opt/tools/apps/scheduler/scheduler/__init__.py

我关注了 & Link2 但运气不好。此应用程序在一台主机上正常工作（比如 host-1），我正在尝试将它部署在 host-2 上。

由于您的应用程序将运行作为守护程序，因此根目录将设置为 /。

确保您的项目目录添加到 python PATH 或让 wsgi 运行应用程序在正确的路径中。

你的 scheduler.wsgi 应该是这样的：

# insert application path in python path
import sys
sys.path.insert(0, "/opt/tools/apps/scheduler")

# launch app
from scheduler import app as application

还要确保 apache user/group (www-data) 可以访问项目：

chown -R www-data:www-data /opt/tools/apps/scheduler
