I just recently came to know abt the module flask for creating website using python and After learning abt it i just made a project of my own. Initially while i tried running this project everything was good i was able to access the local application created in the localhost:5000 by the flask module, but recently when i tried running the same project i wasn't able to access localost:5000. I didn't change anything in the code and i tried re-running the code and restarting chrome multiple times but still i wasn't able to fix the problem.
It would be really helpful if y'all say a good fix to the above mentioned problem.
Thanks in Advance

我最近才开始了解使用Python创建网站的模块烧瓶,在了解了它之后,我做了一个自己的项目。最初,当我尝试运行这个项目时,一切都很好,我能够通过flask模块访问在本地主机:5000中创建的本地应用程序,但是最近,当我尝试运行相同的项目时,我无法访问本地主机:5000。我没有更改代码中的任何内容,我多次尝试重新运行代码并重新启动Chrome,但仍然无法解决该问题。如果你们都说能很好地解决上述问题,那将是非常有帮助的。提前谢谢你

I can recommend some points that usually work for me while reviving some old flask projects.

我可以推荐一些通常对我有用的点子,同时恢复一些旧的烧瓶项目。



  • I usually run Flask applications with pipenv. Check if you have been using it. If it was on pipenv, Pipfile and Pipfile.lock files must be present. In that case, jump to the virtual environment and try running the application there.

    我通常使用pipeenv运行FlaskTM应用程序。检查一下你是否一直在使用它。如果它位于Pipenv上,则必须存在管道文件和管道文件.lock文件。在这种情况下,跳转到虚拟环境并尝试在那里运行应用程序。



  • Check whether local variables like FLASK_APP and FLASK_ENV are set or whether they conflict with the running of the application.

    检查是否设置了FLAASK_APP和FLAASK_ENV等局部变量,或者它们是否与应用程序的运行冲突。



  • Check for updates and if the code is compatible with the version of Flask.

    检查是否有更新,以及代码是否与Flask版兼容。



  • Try checking for other services running on the localhost:5000. If it is, try running the Flask application on some other port.

    尝试检查在本地主机:5000上运行的其他服务。如果是,请尝试在其他端口上运行FlaskTM应用程序。



  • Check for internal conflicts with the Flask application. This may happen due to outdated dependencies.

    检查与烧瓶应用程序的内部冲突。这可能是由于过时的依赖项造成的。



  • Lastly, try updating the system and modules. Check for any outdated third-party modules used in the application and try updating them.

    最后,尝试更新系统和模块。检查应用程序中使用的任何过时的第三方模块,并尝试更新它们。




It would have been more helpful if you would have provided the error. These are some general debugging that I hope will get your application running.

如果您提供了该错误,则会更有帮助。这些是一些常规调试,我希望它们能让您的应用程序运行起来。
