**TypeError: 'module' object is not callable** - uwsgi - flask - python

Question

This is my file structure:

|--cm
|  |--bin
|  |--include
|  |--lib
|  |--app
|  |  |--views.py
|  |  |--all Flask webapp folders
|  |--uwsgi.ini
|  |--run.py

run.py

from app import views

if __name__ == "__main__":
    views.application.run()

part of views.py:

application = Flask(__name__)
application.debug = True
WTF_CSRF_ENABLED = True

uwsgi.ini

[uwsgi]
master = true
processes = 1
socket = /var/www/KRAKEN/public/cm/socket.sock
chmod-socket = 666
plugin = python

nginx.conf

server {
        listen 80;
        server_name server.me www.server.me;
        root /var/www/KRAKEN/public/;
        error_log /var/www/KRAKEN/public/nginx.error.log;
        location / {
           index index.php index.html index.htm;
        }

    location /cm {
        include uwsgi_params;
        uwsgi_param SCRIPT_NAME /cm;
        uwsgi_pass unix:///var/www/KRAKEN/public/cm/socket.sock;
    }

}

When i run

uwsgi --ini uwsgi.ini -w run

I get:

*** Starting uWSGI 2.0.12 (32bit) on [Mon Mar 14 15:45:13 2016] ***

spawned uWSGI worker 1 (pid: 32489, cores: 1)

Then i go to the app route and get:

unable to load app 0 (mountpoint='') (callable not found or import error)

I believe there is something wrong with the callable , tried setting callable = views or callabe = app.views as shown in Flask( name ) but with no success.

The NGINX error log throws:

2016/03/14 17:19:22 [error] 1434#0: *355 upstream prematurely closed connection while reading response header from upstream, client: 190.228.175.122, server: server.me, request: "GET /cm/ HTTP/1.1", upstream: "uwsgi://unix:///var/www/KRAKEN/public/cm/socket.sock:", host: "www.server.me"

Tips?

EDIT: actually, changing callable = views rendered another error:

TypeError: 'module' object is not callable

Which now I belive is a more python related issue...

Edit2: i'm running under a virtual env.

Edit3: just to clarify, the app does work when run with python run.py .

Edit4: detail when i run the uwsgi command.

Edit5: nginx info.

Answer 1

将views.py从cm移到应用程序的根目录并正常工作。

Answer 2

A general solution to this answer is instead of running and troubleshooting

uwsgi --ini uwsgi.ini -w run

Is to instead debug the errors you get from run.py. Give this a shot and resolve any issues -

python run.py

Flask is giving you this TypeError because whatever file that is following this pattern:

from app import views

if __name__ == "__main__":
    views.application.run()

has an issue and wouldn't run with or without UWSGI. UWSGI is hiding the real root cause behind a TypeError.
