Trouble using pyinstaller "No module named '

I trying to use pyinstaller to generate my binary file in python. In my program I use flask_socketio. I try to generate my binary file with that command:

pyinstaller server_websocket.py

Here is the command's result:

[28442] Failed to execute script 'server_websocket' due to unhandled exception!

I work on ubuntu 18.04 with Flask-SocketIO==4.3.1

CodePudding user response：

I finally find the solution. For people who facing the same trouble:

Here is the command I use for create the binary file:

pyinstaller --hidden-import _ssl --hidden-import engineio.async_gevent --hidden-import engineio.async_eventlet  --hidden-import ssl ./server_websocket.py -y

I also need to modify the socketIO call:

app = Flask(__name__)
app.config['SECRET_KEY'] = 'secret!'
socketio = SocketIO(app,     async_mode='gevent')

And import that:

from engineio.async_drivers import gevent
