Question

当我尝试使用this tip在Digital Ocean上运行我的应用程序时，出现错误，无法解决。尝试了一切，并寻找不同的解决方案。在我进入第5步的最后

sudo systemctl start Flask_app

我收到：

simfree@SimFree:~$ sudo systemctl status Flask_app

这是我的文件夹中的一棵树：

Flask_app
    |-main.py
    |-wsgi.py
    |-Flask_app.ini

在我使用

时有效

uwsgi --socket 0.0.0.0:5000 --protocol=http -w wsgi:app

所以这个问题肯定没有与wsgi.py文件链接。

这是我的wsgi.py文件（所需的所有文件）：

from main import app
if __name__ == "__main__":
    app.run()

这是我的Flask_app.ini文件：

[uwsgi]
module = wsgi:app
master = true
processes = 5
socket = Flask_app.sock
chmod-socket = 660
vacuum = true
die-on-term = true

和Flask_app.service：

[Unit]
Description=uWSGI instance to serve Flask_app
After=network.target

[Service]
User=simfree
Group=www-data
WorkingDirectory=/home/simfree/Flask_app
Environment="PATH=/home/simfree/Flask_app/parseenv/bin"
ExecStart=/home/simfree/Flask_app/parseenv/bin/uwsgi --ini Flask_app.ini

[Install]
WantedBy=multi-user.target

如您所见，我拥有所需的一切。花大量时间寻找解决方案，但没有任何帮助。您知道什么会发生此问题吗？非常感谢。
