.exe file gives error when I try to run it-CodePudding

I have a python-flask hangman game, that I tried to wrap into a single executable file using pyinstaller with the following command line:

pyinstaller -w -F --add-data "templates:templates" --add-data "static:static" hangman.py

It seemed to work fine, and created build, dist, as well as the .spec file However, when I try to run the executable, I get the following error:

flask_sqlalchemy/__init__.py:800: UserWarning: SQLALCHEMY_TRACK_MODIFICATIONS adds significant overhead and will be disabled by default in the future.  Set it to True to suppress this warning.

I am relatively new to programming, so please don't mind any wrong use of technical terms.

CodePudding user response：

Try to turn off the reloader like this :

app.run(debug=True, use_reloader=False)

[Edit] it seems like some other application is using the same port. Check it by

netstat -tulpn

To get more information, you can use also :

tasklist

When you got the pid, I'd suggest stop it manually

You can also kill it via command kill:

Taskkill /PID THE_PORT /F
