可执行python文件输出致命错误消息

Question

我编写了一个python脚本，可以与网页进行通信并进行在线订购。除此之外，我还添加了一些GUI，使用户可以选择订单的日期。这是python脚本

但是，我希望将其作为.exe文件运行，只需从桌面双击即可。因此，我已经从git安装了pyinstaller并在cmd（pyinstaller.exe --onefile --windowed --icon=app.ico LunchOrder.py）中运行了简单的代码行。不幸的是，.exe并没有什么作用，它只是弹出"Fatal error detected"消息，而没有任何GUI（我已将其写入脚本本身）。任何帮助，将不胜感激！

Answer 1

[在这里，我将告诉您将.py转换为.exe的更好方法。首先确保您的python已添加到系统PATH，我认为是。如果未查看有关如何将python添加到PATH的一些教程，则可以打开cmd并输入：

pip install pyinstaller

[此后，转到存在LunchOrder.py的路径并在其中打开cmd，在Windows中，您只需在地址栏中键入cmd（清除adressbar后输入），否则打开cmd并导航至您的LunchOrder.py文件所在的路径，只需键入：

pyinstaller -w -F -i "icon.ico" LunchOrder.py

这应该使文件夹dist进入您的.exe文件。确保将.exe复制到dist文件夹并在其中运行。否则您可能仍然会收到致命错误消息。您可以删除所有其他已生成的其他文件，例如build和LunchOrder.spec。如果仍然给您错误，请尝试使用此方法https://www.youtube.com/watch?v=OZSZHmWSOeM
