**類型錯誤：“模塊”對象不可調用**-uwsgi-flask-python

Question

這是我的文件結構：

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

運行文件

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

配置文件

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;
    }

}

當我跑

uwsgi --ini uwsgi.ini -w run

我得到：

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

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

然后我轉到應用程序路線並獲得：

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

我相信callable 有問題，嘗試設置 callable = views 或 callabe = app.views 如 Flask( name ) 所示，但沒有成功。

NGINX 錯誤日志拋出：

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？

編輯：實際上，更改 callable = 視圖會導致另一個錯誤：

類型錯誤：“模塊”對象不可調用

現在我相信這是一個與 python 相關的問題......

Edit2：我在虛擬環境下運行。

Edit3：只是為了澄清，該應用程序在使用python run.py運行時確實有效。

Edit4：當我運行 uwsgi 命令時的詳細信息。

Edit5: nginx 信息。

Answer 1

將views.py從cm移到應用程序的根目錄並正常工作。

Answer 2

此答案的一般解決方案是運行和故障排除

uwsgi --ini uwsgi.ini -w run

而是調試您從 run.py 獲得的錯誤。 試一試並解決任何問題 -

python run.py

Flask 給你這個 TypeError 因為任何遵循這種模式的文件：

from app import views

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

有問題，無論有沒有 UWSGI 都不會運行。 UWSGI 隱藏了 TypeError 背后的真正根本原因。
