这是我在网络服务器上使用 uwsgi 时遇到的错误
*** Operational MODE: single process ***
ModuleNotFoundError: No module named 'app'
unable to load app 0 (mountpoint='') (callable not found or import error)
*** no app loaded. going in full dynamic mode ***
*** uWSGI is running in multiple interpreter mode ***
spawned uWSGI master process (pid: 15225)
spawned uWSGI worker 1 (pid: 15230, cores: 1)
我用了这教程来处理 Flask 中的登录。这与我使用的任何 Flask 项目都不同，因为没有名为 app.py 的文件，而是添加了
app = Flask(__name__)
if __name__ == "__main__":
app.run()
里面有，这让我很困惑，我花了一整天才弄清楚如何部署它，但我无法完成。解决这个问题的每个指南要么使用docker，要么使用app.py构建
我也能够通过在终端中使用命令 flask run 在本地使用它来运行它。但无法使用 uwsgi 并将其添加到守护进程。
希望有人能帮忙。我正在尝试使用 uwsgi uwsgi.ini 在我的服务器上启动它
我的 uwsgi.ini
[uwsgi]

pidfile = basic_flask_template.pid
master = true
