我从以下Github存储库运行app.py：https://github.com/fu-malaria/fu-malaria。该文件可以在flask文件夹中找到。当我运行它时，程序打印以下内容并挂起。
* Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)
* Restarting with stat
libdc1394 error: Failed to initialize libdc1394
* Debugger is active!
* Debugger PIN: 347-063-980
我有x11Forwarding。 libdc1394 error可以忽略。但是，我完全无法调试程序挂起的原因。有任何想法吗？我也粘贴了app.py。

答案 0 :(得分：0)
您使用命令行启动应用程序，但是您是否在端口5000上打开该计算机的Web浏览器？
听起来您正在远程连接到该计算机，因此您需要修改app.run（）参数：
if __name__ == '__main__':
app.run(debug=True, host='0.0.0.0')
再次运行app.py文件时，您应该在print语句中看到地址更改：
python app.py
* Running on http://0.0.0.0:5000/ (Press CTRL+C to quit)
* Restarting with stat
* Debugger is active!
* Debugger pin code: 142-103-744
此时只需在端口5000上运行Flask WSGI应用程序的计算机上指向Web浏览器
运行WSGI应用程序的远程计算机的示例URL为192.168.1.15：
http://192.168.1.15:5000
