Flask and wsgi, ImportError: cannot import name app
大家好,做了一个flask的小应用,配置在digital ocean上,按照digital ocean的配置说明配置后链接描述,访问站点时报500错误。看了下apache的日志,错误原因如下,还请帮忙看看。
日志报错:

我之前在do上部署Flask应用 用的是gunicorn。详情可以看我的博客:http://defshine.github.io/deploy-flask-app-on-do.html
我试着在本地机器上,按照楼主的方式部署了一下,恰巧也遇到这个错误。
最终发现问题时在wsgi的那个文件中
推荐 楼主检查
sys.path.insert(0,"/var/www/qianshan/")
这个路径/var/www/qianshan/ 是项目的路径吗?
比如的项目放在 /home/xin/workspace/python/flaskapp这里那我的配置就是:
import sys
import logging
logging.basicConfig(stream=sys.stderr)
sys.path.insert(0,"/home/xin/workspace/python/flaskapp/")
from app import app as application
application.secret_key = 'Add your secret key'
把init.py中
if name == 'main':
app.run()
这两句删除.
另新建一个文件runsvr,py, 内容如下:
from init import app
if name == 'main':
app.run()
平时调试的时候
用python runsvr.py来运行
