** TypeError：＆＃39; module＆＃39;对象不可调用** - uwsgi - flask - python

Question

这是我的文件结构：

|--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()

views.py：

的一部分

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;
    }

}

当我跑步时

uwsgi --ini uwsgi.ini -w run

我明白了：

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

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

然后我转到app路线并获取：

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

我认为可调用有问题，尝试设置callable = views或callabe = app.views，如Flask（ name ）所示，但没有成功。

NGINX错误日志抛出：

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"

提示？

编辑：实际上，更改callable = views会再次出现错误：

TypeError：＆＃39; module＆＃39;对象不可调用

现在我相信这是一个与python相关的问题......

Edit2：我在虚拟环境下运行。

Edit3：只是为了澄清一下，当使用 python run.py 运行时，该应用程序可以正常工作。

Edit4：运行uwsgi命令时的详细信息。

Edit5：nginx info。

Answer 1

将views.py从cm移动到app root dir并运行。

Answer 2

此答案的一般解决方案是运行和故障排除

uwsgi --ini uwsgi.ini -w run

改为调试您从 run.py 获得的错误。试一试并解决任何问题 -

python run.py

Flask 给你这个 TypeError 因为任何遵循这种模式的文件：

from app import views

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

有问题，无论有没有 UWSGI 都无法运行。 UWSGI 隐藏了 TypeError 背后的真正根本原因。
